"Speed of light", abbreviated as SOL, (compute-only) data from my Xeon Phi 7210 (KNL) DAP workstation.
[Note: The data acquired in these folders used the default environment variable KMP_AFFINITY=scatter, so no special environment variable was set before the compiled code was run.]
1. Unzip the SOL_ANIMATIONS_Dunham.zip file.
2. Within the extracted file folder are two folders, one for double precision and one for single precision. Move to one of these two folders. The instructions below assume you move to the double precision folder.
3. If you have Mathematica installed, simply double-click the AVX512doublefmaMASTER.nb and the Mathematica notebook should open.
If you do NOT have Mathematica installed, download the free CDF player at http://demonstrations.wolfram.com/download-cdf-player.html and install the CDF player for your Windows, Linux, or MacOS platform. When the CDF player is installed, navigate to the double precision folder mentioned in item 2. and double-click AVX512doublefmaMASTER.cdf (CDF = Computable Document Format) It is important that you double-click the .cdf version, not the .nb version.
4. Once the Mathematica notebook opens, locate the "Evaluation" menu at the top of notebook window. In the "Evaluation" drop-down menu, select "Evaluate Notebook".
[On the same Evaluation drop-down menu you should see that "Dynamic Updating Enabled" is already selected; that's the default. If it is not selected, select it. Dynamic Updating is required for the interactive manipulation near the middle of the notebook.]
5. Once you have selected "Evaluate Notebook", the notebook will take about 1-2 minutes to evaluate; the data from 25 files need to read in. [I don't recommend running the Mathematica notebook in .nb or .cdf formats on a Xeon Phi workstation--it will disappointingly slow because only one 1.3 GHz thread will run! Blame Wolfram, not Intel.]
You may see that the notebook window is scrolling down on its own. If you move your mouse to the right side of the notebook screen, but not all of the way into the window scroll bar, you will see the cell markers used within a standard Mathematica notebook. These cell markers will be thick black if the cell is still awaiting evaluation, and light blue if the cell has already been evaluated.
6. Find the interactive animation window near the middle of the notebook. You should be able to simple press the Play button (right-pointing arrowhead) and the animation will begin. You can press radio buttons that allow you to select a specific fma case (1 through 25) and a specific trial (1, 2, 3, 4, 5). The control panel for the animation needs to be somewhere on your screen; the animation stops if your move the control portion of the animation off screen.
