Phoenix Business Journal: Climbing the steepest technology slope – 5 suggestions for better productivity software integration

Most companies invest a lot of money into software productivity tools and then expect the various tools to work together. The reality is that connecting different products is hard, and is a common cause why many implementations fail. In “Climbing the steepest technology slope: 5 suggestions for better productivity software integration” I make some suggestions based on real-world experience.

Phoenix Business Journal: Digital fingerprint: The emerging technology that will identify the world around us

The concept of digital fingerprints a technology that is finding its way into everything from food safety to tracking online fraud. It is so powerful that all technology companies should know what it is and understand how it plays in their products and services. I take a look at what it is and how to take advantage of it in “Digital fingerprint: The emerging technology that will identify the world around us.

Phoenix Business Journal: Cutting the cord and the freight train of change headed toward all of us

While looking at disconnecting my home from a cable provider, I came to the realization that millions of other consumers were doing the same thing. This would change Cable TV forever. And what about other technologies, like the ones our company is built on. In “Cutting the cord and the freight train of change headed toward all of us” I muse on what could happen and what we can do about it

Finding curve directions in ANSYS SpaceClaim   

As it so often does, another blog article idea came from a tech support question that I received the other day. “How do you view edge directions in ANSYS SpaceClaim?

You can do it in Mechanical, on the Edge Graphics Options Toolbar:

This will turn on arrows so that you can see the edge directions. The directions of the edges or curves affects things like mesh biasing factors and mass flow rate boundary conditions. You need to make sure that all your pipes in a thermal analysis, for instance, are flowing in the same direction.

(I have also had three tech support calls about weird spikes showing up in customers’ geometry. The Display Edge Direction is also how you turn those off.)

In ANSYS SpaceClaim, there is no way to just display the edge directions. The directions are controlled by which point you pick first while sketching, so if you are careful, you can make sure they are all consistent. But that doesn’t help when you read in CAD files.  So I thought I would share with you what I found, after a little bit of digging and playing. I discovered that the Move Tool behaves in a very specific way, a way that we can use for our need.

When you pick on the edge of a surface or solid, or even a straight sketched line, the red arrow of the Move Tool will point in the direction of the curve. These directions match what gets shown in Mechanical.

For splines, it’s a little bit different. If you just pick a spline with the Move Tool, the triad will align with the global coordinate system.

To see the spline direction, you first have to hover over the spline, to show the vertices of the spline.

Then you can pick an interior vertex, and the Blue arrow of the Move Tool will follow the spline direction.

This only works at the interior vertices, and not at the ends. At the ends, the Blue tool arrow will always point outward from the spline endpoints, so you won’t really know which is the correct spline direction.

I have also found that this technique does not work on sketched circles or arc because the tool always anchors to the center of the curve, and not to the curve itself.  You can, however, use the Repair>Fit Curves tool to convert arcs to splines, using only the Spline option. Then the Move tool will show those directions as described above.  For circles, you have to make one more step, and first, use the Split tool to split the circle into two arcs.  All that though is, in my opinion, more work than it’s worth.

I hope this helps make your lives just a little easier. Have a great day.

Spectre Side-Channel and Meltdown – How will living in this new reality affect the world of numerical simulation?

Literally, while I was sorting and running benchmarks and prepping the new benchmarks data originally titled. ANSYS Release 18.2 Ball Grid Array Benchmark information using two sixteen core INTEL® XEON® Gold 6130 CPU’s. I noticed that my news feeds had started to blow up with late breaking HPC news. The news as you may have guessed is the Spectre and Meltdown flaws that were recently published.

I thought to myself “Well this is just great the benchmarks that I just ran are no longer relevant.  My next thought was wait now I can show a real world example of exactly a percentage change. I have waited this long to run the ANSYS numerical simulation benchmarks on this new CPU architecture. I can wait a little longer to post my findings.” What now? Oh my more Late Breaking News! Research findings, Execution orders no barriers! Side channels used to get access to private address areas of the hardware! Wow this is a bad day. As I sat reading more news, then I drifted off daydreaming, then back to  my screen then the clock on the wall, great it is 2am already!, just go home…” Then thoughts immediate shifted and I was back thinking about indeed, how these hardware flaws impact the missing middle market? HPC numerical simulation!!! I dug in deep and pressed forward content with starting over on the benchmarks knowing after the patches released around Jan 9th will be a whole new world.

I decided to spare the ugly details related to the Spectre array bounds/brand prediction attack flaws. The out of order meltdown vulnerabilities! UGH! I seriously believe that someone has AI writing news articles written five or six different ways with each somehow saying the same thing. I also provide the links to the information and legal statements directly from a who’s who list of accountable parties:

Executive Summary:

  • * Remember every case is different so please do your run your own tests to verify how this new reality affects your hardware and software environment.*
    • Due to costs this machine has a single NVMe M.2 for the primary drive with a single 2TB SATA drive for its Mid-Term Storage area.
  • What was the impact for my benchmark?
    • Positive takeaway:
      • In all of the years of running the sp5 benchmark. I recorded the fastest benchmark time using this CUBE w32s, dual INTEL® XEON® Gold 6130 CPU workstation.
      • Using all thirty two cores 125.7 seconds for Solution Time (Time Spent Computing Solution).
        • Next, Coming in at 135.7 seconds the Solution Time metric after running the OS patches is my second fastest data point for the ANSYS sp5 benchmark.
          • ANSYS sp5 benchmark data – PADT, Inc. Currently from 2005 until this time.
      • The Solution Times continued to solve faster with each bump in cores.
      • Performance per dollar was maximized in this configuration.
    • Depending on number of cores used that I used for the ANSYS sp5 benchmark. I give the actual data below showing the percentage differences before and after:
      • Largest percentage difference:
        • Solution Time: -9.81% using four CPU cores.
        • Total Time: -7.87% using two CPU cores.
  • The need to turn the security screws down within your corporate enterprise network is now.
  • A rogue malicious agent needs to be on the inside of your corporate network to execute any sort of crafted attack. Much of these details are outlined in the Project Zero abstract.
  • Pay extra attention to just who you let on your internal network.
    • I reiterate the recommendations of many security professionals that you should already be restricting your internal company network and workstations to employee use. If you are not sure ask again.
  1. Spectre flaw:
    1. INTEL, ARM & AMD CPU’s are affected by the Spectre array bounds hardware attacks.
  2. Meltdown flaw:
    1. INTEL CPU’s and some ARM high performance CPU’s are affected by the “easier to exploit” Meltdown vulnerability.

I am also interested to see how continued insertion of code barriers and changed memory mappings affect my gaming performance. Haha! No, I am just kidding my numerical simulation performance benchmarks.

Clarifications & Definitions:

  • Unpatched Benchmark Data – No mitigation patches from Microsoft and NVidia addressing the Spectre and Meltdown flaws have been applied to the Windows 10 Professional OS running on the CUBE w32s that I use in this benchmark.
  • Patched Benchmark Data – I installed the batch of patches released by Microsoft as well as the NVDIA graphics card driver update released by NVIDIA addressing. NVIDIA indicates in their advisory that “their hardware their GPU hardware is not affected but they are updating their drivers to help mitigate the CPU security issue.” Huh? Installing now…
  • Solution Time – The amount of time in seconds that the CPU’s spent computing the solution. “The Time Spent Computing Solution”
  • Total Time – Total time in seconds that the entire process took. How the solve felt to the user also known as wall clock time.

The CUBE machine that I used in this ANSYS Test Case represent a fine balance based on price, performance and ANSYS HPC licenses used.

  • CUBE w32s, INTEL® XEON® Gold 6130 CPU, 128GB’s DDR4-2667MHz (1Rx4) ECC REG DIMM, Windows 10 Professional, ANSYS Release 18.2, INTEL MPI 5.0.1.3, 32 Total Cores, NVIDIA QUADRO P4000, Samsung EVO 960 Pro NVMe M.2, Toshiba 2TB 7200 RPM SATA 3 Drive.
  • Other notables, are you still paying attention?
    • My Supermicro X11Dai-N BIOS Settings:
      • BIOS Version: 2.0a
      • Execute Disable Bit: DISABLE
      • Hyper threading: ON

      • CPU C3 Report: DISABLE
      • CPU C6 Report: DISABLE
      • Enhanced Halt State: DISABLE
    • With a read performance of up to 3,200MB/s and write performance of up to 1,900 MB/s using the Samsung NVMe M.2 drive was to tempting to pass up as my solve and temp solve area location. The bandwidth from the little feller was to impressive and continued to impress throughout the numerical simulation benchmarks.

My first overall impressions of this configuration is Wow! this workstation is fast, quiet and as you will see number crunches its way right on through to being my fastest documented workstation benchmark in this class. This extremely challenging and I/O intensive ANSYS benchmark is no match for this solver! Thumbs up and cheers to happy solving!
