Getting to Know PADT: High Performance Computing (HPC) IT Support Services

 This post is the twelfth installment in our review of all the different products and services PADT offers our customers. As we add more, they will be available here.  As always, if you have any questions don’t hesitate to reach out to info@padtinc.com or give us a call at 1-800-293-PADT.

The fact of the matter is, to be blunt, that building, maintaining, and optimizing systems for high-performance computing (HPC) is different than any other part of the IT world.  That is why most companies engaged in simulation who use HPC often struggle with their computers and networks. There is nothing wrong with their IT departments, they simply don’t have the manpower or the experience to support HPC systems. And that is why PADT offers IT support services tailored towards the needs of simulation users.  We bridge that gap between the unique needs of HPC for simulation and customer’s existing IT infrastructure.

We started offering this service simply because customers asked us to. As part of  ANSYS technical support duties, we kept getting calls from customers who were just not getting good performance out of some very expensive computer hardware. After looking into it we often found that they had the wrong hardware, it was configured wrong for HPC, or there was unnecessary overhead on the system.  In each case, we got together with the customer’s IT department and the users to understand the problem and implement fixes.

PADT’s IT team can offer a variety of services, including, but not limited to:

  • Implementing data management software
  • Performance benchmarking
  • Troubleshooting and Debugging Systems
  • High-performance Network design and installation
  • Making things run faster
  • System tuning
  • System design and configuration
  • Upgrading existing hardware
  • Installing software packages
  • Setting up queuing and monitoring tools

Focused on Performance

Most computer systems and the IT infrastructure that supports them, in the commercial world, are focused on security first, operating cost second, then performance.  And these are the right priorities. But in the HPC world, those same systems and infrastructure have to be focused on performance, with robustness second.  Security is important, but you solve that problem by isolating the systems and controlling access. PADT’s IT team gets this and because we run a large HPC infrastructure for our own simulation consulting business, they know how to set things up right and keep them tuned for performance.

A Partnership Between Users, IT, and PADT

Our deep knowledge of scientific computing and the hardware it runs on is only one part of our success in this area. The other is knowing how to be that translator between IT and the users of demanding numerical software packages.  We understand why IT can or can not open certain ports, and why the user needs those ports. We get the desire to establish a company-wide policy using remote drives that use RAID 1. We also know that doing that kills HPC performance. That starts the conversation on why users need local drives in RAID 0 for their number crunching.

The examples go on and on and involve memory, network fabric, different versions of MPI for each solver, and much more.  Often times just being able to explain these issues in terms everyone can understand is the greater value PADT can add.  And then our IT experts will be there with the customer’s IT experts at 11:30 PM installing those GPU cards and configuring them.

Maximize the Return on your HPC Investment

The cold hard reality is that companies spend large sums on advanced hardware, software, and infrastructure. Why not spend a little more to make sure you are getting the most from that sizeable investment.  PADT is here to help, to work with your IT and users, to get the most out of the tools you have.   Please don’t hesitate to call us at 480.813.4884 or send an email to info@padtinc.com to learn more.

Getting to Know PADT: Cube Simulation Computers

This post is the seventh installment in our review of all the different products and services PADT offers our customers. As we add more, they will be available here.  As always, if you have any questions don’t hesitate to reach out to info@padtinc.com or give us a call at 1-800-293-PADT.

“It is done running already? What machine did you run that on? Your desktop? How do I buy one?”  That serious of questions from an ANSYS customer of PADT’s is how CUBE Computers became one of our product offerings.  We offer a complete line of six standard systems to meet the needs of the most demanding, and cost-conscious, users.

The problem is that in the world of advanced numerical simulation, most off-the-shelf computers just don’t perform like they should. They are expensive and are weighed down with unnecessary accessories and slowed down by poor configuration.  Because PADT has been building our own computers for over twenty years for the sole purpose of running simulation models, we know how to configure boxes that are optimized for that sweet spot everyone is looking for.  Our engineers and IT staff work with customers to find the right standard system, or to customize a unique system that is ideal.

We break our standard models into three families: Workstations, Servers, and Cluster Appliances.  Although each type can be heavily customized, we have pre-configured the following systems to make it easy for users to quickly get what they need:

Each machine comes with maintenance and support that is also tuned to the customer’s needs – from basic parts only warranty to same-day on-site support. You can also have us install the system and your simulation software.  Whatever you need, we can deliver.

Over one hundred customers, many who have purchased multiple systems from us over the years, have worked with PADT’s team to obtain an optimized computer system that maximizes the return on their simulation investment. Reach out to our CUBE Computer System team and http://www.directics.com/altera-fpga/ let them help you ” Discover What You Need.”

Combining ANSYS Simulation with HPC

Engineering simulation has become much more prevalent in engineering organizations than it was even 5 years ago.  Commercial tools have gotten significantly easier to use whether you are looking at tools embedded within CAD programs or the standalone flagship analysis tools.  The driving force behind these changes are to ultimately let engineers and companies understand their design quicker with more fidelity than before.

Engineering simulation is one of those cliché items where everyone says “We want more!”  Engineers want to analyze bigger problems, more complex problems and even do large scale design of experiments with hundreds of design variations – and they want these results instantaneously.   They want to be able to quickly understand their designs and design trends and be able to make changes accordingly so then can get their products optimized and to the market quicker.

ANSYS, Inc. spends a significant amount of R&D in helping customers get their results quicker and a large component of that development is High Performance Computing, or HPC.  This technology allows engineers to solve their structural, fluid and/or electromagnetic analyses across multiple processors and even across multiple computing machines.  Engineers can leverage HPC on laptops, workstations, clusters and even full data centers.

PADT is fortunate to be working with Nimbix, a High Performance Computing Platform that easily allowed us to quickly iterate through different models with various cores specified.  It was seamless, easy to use, and FAST!

Let’s take a look at four problems: Rubber Seal FEA, Large Tractor Axle Model, Quadrocopter CFD model and a Large Exhaust CFD model.  These problems cover a nice spectrum of analysis size and complexity. The CAD files are included in the link below.

Click here to download geometry files that were used in the following benchmarks

TRACTOR AXLE FEA

This model has several parts all with contact defined and has 51 bolts that have pretension defined.  A very large but not overly complex FEA problem.  As you can see from the results, even by utilizing 8 cores you can triple your analysis throughput for a work day.  This leads to more designs being analyzed and validated which gives engineers the results they need quicker.

SUMMARY

  • 58 Parts
  • 51 x Bolts with Pretension

RUBBER SEAL FEA

The rubber seal is actually a relatively small size problem, but quite complex.  Not only does it need full hyperelastic material properties defined with large strain effects included, it also includes a leakage test.  This will pressurize any exposed areas of the seal.  This will of course cause some deformation which will lead to more leaked surfaces and so on.  It basically because a pressure advancing solution.

From the results, again you can see the number of models that can be analyzed in the same time frame is signifcantly more.  This model was already under an hour, even with the large nonlinearity, and with HPC it was down to less than half an hour.

SUMMARY

  • 6 Parts
  • Mooney Rivlin Hyperelastic Material
  • Seal Leakage with Advancing Pressure Load
  • Frictional Contact
  • Large Deformation
  • 42K Elements, 58K Nodes

QUADROCOPTER DRONE CFD

The drone model is a half symmetry model that includes 2 rotating domains to account for the propellers.  This was ran as a steady state simulation using ANSYS Fluent.  Simply utilizing 8 cores will let you solve 3 designs versus 1.

EXHAUST CFD

The exhaust model is a huge model with 33 million elements with several complicated flow passages and turbulence.  This is a model that would take over a week to run using 1 core but with HPC on a decent workstation you can get that down to 1 day.  Leveraging more HPC hardware resources such as a cluster or using a cloud computing platform like Nimbix will see that drop to 3 hours.  Imagine getting results that used to take over 1 week that now will only take a few hours.  You’ll notice that this model scaled linearly up to 128 cores.  In many CFD simulations the more hardware resources and HPC technology you throw at it, the faster it will run.

As seen from the results leveraging HPC technology can be hugely advantageous.  Many simulation tools out there do not fully leverage solving on multiple computing machines or even multiple cores.  ANSYS does and the value is easily a given.  HPC makes large complex simulation more practical as a part of the design process timeline.  It allows for greater throughput of design investigations leading to better fidelity and more information to the engineer to develop an optimized part quicker.

Activating Hyperdrive in ANSYS Simulations

punch-it-chewie-ansysWith PADT and the rest of the world getting ready to pile into dark rooms to watch a saga that we’ve been waiting for 10 years to see, I figured I’d take this opportunity to address a common, yet simple, question that we get:

“How do I turn on HPC to use multiple cores when running an analysis?”

For those that don’t know, ANSYS spends a significant amount of resources into making the various solvers it has utilize multiple CPU processors more efficiently than before.  By default, depending on the solver, you are able to use between 1-2 cores without needing HPC licenses.

With the utilization of HPC licenses, users can unlock hyperdrive in ANSYS.  If you are equipped with HPC licenses it’s just a matter of where to look for each of the ANSYS products to activate it.

ANSYS Mechanical

Whether or not you are performing a structural, thermal or explicit simulation the process to activate multiple cores is identical.

  1. Go to Tools > Solve Process Settings
  2. The Solve Process Settings Window will pop up
  3. Click on Advanced to open up the Advanced Settings window
  4. You will see an option for Max number of utilized cores
  5. Simply change the value to your desired core count
  6. You will see below an option to allow for GPU acceleration (if your computer is equipped with the appropriate hardware)
  7. Select the GPU type from the dropdown and choose how many GPUs you want to utilize
  8. Click Ok and close
hyperdrive-ansys-f01
Go the proper settings dialog
hyperdrive-ansys-f02
Choose Advanced…
hyperdrive-ansys-f03
Specify the number of cores to use

Distributed Solve in ANSYS Mechanical

One other thing you’ll notice in the Advanced Settings Window is the option to turn “Distributed” On or Off using the checkbox.

In many cases Distributing a solution can be significantly faster than the opposite (Shared Memory Parallel).  It requires that MPI be configured properly (PADT can help guide you through those steps).  Please see this article by Eric Miller that references GPU usage and Distributed solve in ANSYS Mechanical

hyperdrive-ansys-f04
Turn on Distributed Solve if MPI is Configured

ANSYS Fluent

Whether launching Fluent through Workbench or standalone you will first see the Fluent Launcher window.  It has several options regarding the project.

  1. Under the Processing Options you will see 2 options: Serial and Parallel
  2. Simply select Parallel and you will see 2 new dropdowns
  3. The first dropdown lets you select the number of processes (equal to the number of cores) to use in not only during Fluent’s calculations but also during pre-processing as well
Default Settings in Fluent Launch Window
Default Settings in Fluent Launch Window
Options When Parallel is Picked
Options When Parallel is Picked

ANSYS CFX

For CFX simulations through Workbench, the option to activate HPC exists in the Solution Manager

  1. Open the CFX Solver Manager
  2. You will see a dropdown for Run Mode
  3. Rather than the default “Serial” option choose from one of the available “Parallel” options.
  4. For example, if running on the same machine select Platform MPI Local Parallel
  5. Once selected in the section below you will see the name of the computer and a column called Partitions
  6. Simply type the desired number of cores under the Partitions column and then either click “Save Settings” or “Start Run”
Change the Run Mode
Change the Run Mode
Specify number of cores for each machine
Specify number of cores for each machine

ANSYS Electronics Desktop/HFSS/Maxwell

Regardless of which electromagnetic solver you are using: HFSS or Maxwell you can access the ability to change the number of cores by going to the HPC and Analysis Options.

  1. Go to Tools > Options > HPC and Analysis Options.
  2. In the window that pops up you will see a summary of the HPC configuration
  3. Click on Edit and you will see a column for Tasks and a column for Cores.
  4. Tasks relate to job distribution utilizing Optimetrics and DSO licenses
  5. To simply increase the number of cores you want to run the simulation on, change the cores column to your desired value
  6. Click OK on all windows
hyperdrive-ansys-f09
Select the proper settings dialog
hyperdrive-ansys-f10
Select Edit to change the configuration
Specify Tasks and Cores
Specify Tasks and Cores

There you have it.  That’s how easy it is to turn on Hyperdrive in the flagship ANSYS products to advance your simulations and get to your endpoint faster than before.

CoresOnDemand: Helping Engineers Do Their Magic

CoresOnDemand-Logo-120hEngineers Do Magic

In the world of simulation there are two facts of life. First, the deadline of “yesterday would be good” is not too uncommon. Funding deadlines, product roll-out dates, as well as unexpected project requirements are all reliable sources for last minute changes. Engineers are required to do quality work and deliver reliable results in limited time and resources. In essence perform sorcery.

af-01

Second, the size and complexity of models can vary wildly. Anything from fasteners and gaskets to complete systems or structures can be in the pipeline. Engineers can be looking at any combination of hundreds of variables that impact the resources required for a successful simulation.

Required CPU cores, RAM per core, interconnect speeds, available disk space, operating system and ANSYS version all vary depending on the model files, simulation type, size, run-time and target date for the results.

Engineers usually do magic. But sometimes limited time or resources that are out of reach can delay on-time delivery of project tasks.

At PADT, We Can Help

PADT Inc. has been nostrils deep in engineering services and simulation products for over 20 years. We know engineering, we know how to simulate engineering and we know ANSYS very well. To address the challenges our customers are facing, in 2015 PADT introduced CoresOnDemand to the engineering community.

af-02

CoresOnDemand offers the combination of our proven CUBE cluster, ANSYS simulation tools and the PADT experience and support as an on demand simulation resource. By focusing on the specific needs of ANSYS users, CoresOnDemand was built to deliver performance and flexibility for the full range of applications. Specifics about the clusters and their configurations can be found at CoresOnDemand.com.

CoresOnDemand is a high performance computing environment purpose built to help customers address numerical simulation needs that require compute power that isn’t available or that is needed on a temporary basis.

Call Us We’re Nice

CoresOnDemand is a new service in the world of on-demand computing. Prospective customers just need to give us a call or send us an inquiry here to get all of their questions answered. The engineers behind CoresOnDemand have a deep understanding of the ANSYS tools and distributed computing and are able to asses and properly size a compute environment that matches the needed resources.

Call us we’re nice!

Two Halves of the Nutshell

The process for executing a lease on a CoresOnDemand cluster is quite straight forward. There are two parts to a lease:

PART 1: How many cores & how long is the lease for?

By working with the PADT engineers – and possibly benchmarking their models – customers can set a realistic estimate on how many cores are required and how long their models need to run on the CoresOnDemand clusters. Normally, leases are in one-week blocks with incentives for longer or regular lease requirements.

Clusters are leased in one-week blocks, but we’re flexible.

Part 2: How will ANSYS be licensed?

An ANSYS license is required in order to run on the CoresOnDemand environment.  A license lease can be generated by contacting any ANSYS channel partner. PADT can generate license leases in Arizona, Colorado, New Mexico, Utah & Nevada. Licenses can also be borrowed from the customer’s existing license pool.

An ANSYS license may be leased from an ANSYS channel partner or borrowed from customer’s existing license pool.

Using the Cluster

Once the CoresOnDemand team has completed the cluster setup and user creation (takes a couple of hours for most cases), customers can login and begin using the cluster. The CoresOnDemand clusters allow customers to use the connection method they are comfortable with. All connections to CoresOnDemand are encrypted and are protected by a firewall and an isolated network environment.

Step 1: Transfer files to the cluster:

Files can be transferred to the cluster using Secure Copy Protocol which creates an encrypted tunnel for copying files. A graphical tool is also available for Windows users (& it’s freeJ). Also, larger files can be loaded to the cluster manually by sending a DVD, Blu-ray disk or external storage device to PADT. The CoresOnDemand team will mount the volume and can assist in the copying of data.

Step 2: Connect to the cluster and start jobs

Customers can connect to the cluster through an SSH connection. This is the most basic interface where users can launch interactive or batch processing jobs on the cluster. SSH is secure, fast and very stable. The downside of SSH is that is has limited graphical capabilities.

Another option is to use the Nice Software Desktop Cloud Visualization (DCV) interface. DCV provides enhanced interactive 2D/3D access over a standard network. It enables users to access the cluster from anywhere on virtually any device with a screen and an internet connection. The main advantage of DCV is the ability to start interactive ANSYS jobs and monitor them without the need for a continuous connection. For example, a user can connect from his laptop to launch the job and later use his iPad to monitor the progress.

af-04

Figure 1. 12 Million cell model simulated on CoresOnDemand

The CoresOnDemand environment also has the Torque resource manager implemented where customers can submit multiple jobs to a job queue and run them in sequence without any manual intervention.

Customers can use SCP or ship external storage to get data on the cluster. SSH or DCV can be used to access the cluster. Batch, interactive or Torque scheduler can be used to submit and monitor jobs.

All Done?

Once the simulation runs are completed customers usually choose one of two methods to transfer data back. First is to download the results over the internet using SCP (mentioned earlier) or have external media shipped back (External media can be encrypted if needed).

After the customer receives the data and confirms that all useful data was recovered from the cluster, CoresOnDemand engineers re-image the cluster to remove all user data, user accounts and logs. This marks the end of the lease engagement and customers can rest assured that CoresOnDemand is available to help…and it’s pretty fast too.

At the end of the lease customers can download their data or have it shipped on external media. The cluster is later re-imaged and all user data, accounts & logs are also deleted in preparation for the next customer.

Five Key Differentiators

The things that make CoresOnDemand different than most other cloud computing providers are:

  1. CoresOnDemand is a non-traditional cloud. It is not an instance based cluster. There is no hypervisor or any virtualization layer. Users know what resources are assigned exclusively to them every time. No layers, no emulation, no delay and no surprises.
  2. CoresOnDemand utilizes all of the standard software designed to maximize the full use of hardware features and interconnect. There are no layers between the hardware and operating system.
  3. CoresOnDemand utilizes hardware that is purpose built and benchmarked to maximize performance of simulation tools instead of a general purpose server on caffeine.
  4. CoresOnDemand provides the ability to complete high performance runs on the compute specialized nodes and later performing post processing on a post-processing appropriate node.
  5. CoresOnDemand is a way to lease compute nodes completely and exclusively for the specified duration including software licenses, compute power and hardware interconnect.

CoresOnDemand is backed up by over 20 years of PADT Inc. experience and engineering know-how. Looking at the differentiating features of CoresOnDemand, it becomes apparent that the performance and flexibility of this solution are great advantages for addressing numerical simulation requirements of any type.

Announcing CoresOnDemand.com – Dedicated Compute Power when you Need It

CoresOnDemand-Logo-120hWe are pleased to announce a new service that we feel is remote solving for FEA and CFD done right: CoresOnDemand.com.  We have taken our   proven CUBE Simulation Computers and built a cluster that users can simply rent.  So you get fast hardware, you get it all to your self, and you receive fantastic support from the ANSYS experts at PADT.

It is not a time share system, it is not a true "cloud" solution.  You tell us how many nodes you need and for how long and we rent them to you. You can submit batch or you can configure the machines however you need them.  Submit on the command line, through a batch scheduler, or run interactive. And when you are done, you do not have to send your files back to your desktop. We've loaded NICE DCV so you can do graphics intense pre- and post-processing from work or home, over the internet to our head nodes.  You can even work through your iPad.

If you visit our Blog page a lot, you may have noticed the gray cloud logo with a big question mark next to it. If you guessed that was a hint that we were working on a cloud solution for ANSYS users, you were correct. We've had it up and running for a while but we kept "testing" it with  benchmarks for people buying CUBE computers. Plus we kept tweaking the setup to get the best user experience possible.  With today's announcement we are going live.

We created this service for a simple reason. Customers kept calling or emailing and asking if they could rent time on our machines.  We got started with the hardware but also started surveying and talking to users. Everyone is talking about the cloud and HPC, but we found few providers understood how to deliver the horsepower people needed in a usable way, and that users were frustrated with the offerings they had available. So we took our time and built a service that we would want to use, a service we would find considerable value in.

You can learn more by visiting www.CoresOnDemand.com. Or by reading the official press release included below. To get your started, here are some key facts you should know:

  1. We are running PADT CUBE computers, hooked together with infiniband. They are fast, they are loaded with RAM, and they have a ton of disk space. Since we do this type of solving all the time, we know what is needed
  2. This is a Bring Your Own License (BYOL) service. You will need to lease the licenses you need from whoever you get your ANSYS from.  As an ANSYS Channel partner we can help that process go smoothly.
  3. You do not share the hardware.  If you reserve a node, it is your node. No one else but your company can log in.  You can rent by the week, or the day.
  4. When you are done, we save the data you want us to save and then wipe the machines.  If you want us to save your "image" we can do that for a fee so next time you use the service, we can restore it to right where you were last time.
  5. Right now we are focused on ANSYS software products only. We feel strongly about focusing on what we know and maximizing value to the customers.
  6. This service is backed by PADT's technical support and IT staff. You would be hard pressed to find any other HPC provider out there who knows more about how to run ANSYS Mechanical, ANSYS Mechanical APDL, ANSYS FLUENT, ANSYS CFX, ANSYS HFSS, ANSYS MAXWELL, ANSYS LS-DYNA, ANSYS AUTODYN, ICEM CFD, and much more.

Press Release:

CoresOnDemand.com Launches as Dedicated ANSYS Simulation
High Performance Cloud Compute Resource 

PADT launches CoresOnDemand.com, a dedicated resource for users who need to run ANSYS simulation software in the cloud on optimized high performance computers.

Tempe, AZ – April 29, 2015 – Phoenix Analysis & Design Technologies, Inc. (PADT), the Southwest’s largest provider of simulation, product development, and 3D Printing services and products, is pleased to announce the launch of a new dedicated high performance compute resource for users of ANSYS simulation software – CoresOnDemand.com.  The team at PADT used their own experience, and the experience of their customers, to develop this unique cloud-based solution that delivers exceptional performance and a superior user experience. Unlike most cloud solutions, CoresOnDemand.com does not use virtual machines, nor do users share compute nodes. With CoresOnDemand.com users reserve one or more nodes for a set amount of time, giving them exclusive access to the hardware, while allowing them to work interactively and to set up the environment the way they want it.

The cluster behind CoresOnDemand.com is built by PADT’s IT experts using their own CUBE Simulation Computers (http://www.padtinc.com/cube), systems that are optimized for solving numerical simulation problems quickly and efficiently. This advantage is coupled with support from PADT’s experienced team, recognized technical experts in all things ANSYS. As a certified ANSYS channel partner, PADT understands the product and licensing needs of users, a significant advantage over most cloud HPC solutions.

“We kept getting calls from people asking if they could rent time on our in-house cluster. So we took a look at what was out there and talked to users about their experiences with trying to do high-end simulation in the cloud,” commented Eric Miller, Co-Owner of PADT. “What we found was that almost everyone was disappointed with the pay-per-cpu-second model, with the lack of product understanding on the part of the providers, and mediocre performance.  They also complained about having to bring large files back to their desktops to post-process. We designed CoresOnDemand.com to solve those problems.”

In addition to exclusive nodes, great hardware, and ANSYS expertise, CoresOnDemand.com adds another advantage by leveraging NICE Desktop Cloud Visualization (https://www.nice-software.com/products/dcv) to allow users to have true interactive connections to the cluster with real-time 3D graphics.  This avoids the need to download huge files or running blind in batch mode to review results. And as you would expect, the network connection and file transfer protocols available are industry standards and encrypted.

The initial cluster is configured with Intel and AMD-based CUBE Simulation nodes, connected through a high-speed Infiniband interconnect.  Each compute node has enough RAM and disk space to handle the most challenging FEA or CFD solves.  All ANSYS solvers and prep/post tools are available for use including: ANSYS Mechanical, ANSYS Mechanical APDL, ANSYS FLUENT, ANSYS CFX, ANSYS HFSS, ANSYS MAXWELL, ANSYS LS-DYNA, ANSYS AUTODYN, ICEM CFD, and much more. Users can serve their own licenses to CoresOnDemand.com or obtain a short-term lease, and PADT’s experts are on hand to help design the most effective licensing solution.

Pre-launch testing by PADT’s customers has shown that this model for remote on-demand solving works well.  Users were able to log in, configure their environment from their desktop at work or home, mesh, solve, and review results as if they had the same horsepower sitting right next to their desk.
