Note: JupyterHub with JupyterLab Install using Conda

Posted on April 17, 2020 by Dr. Donald Kinghorn

This is a quick note about setting up a JupyterHub server and JupyterLab using conda with Anaconda Python.

HPC Parallel Performance for 3rd gen Threadripper, Xeon 3265W and EPYC 7742 (HPL HPCG Numpy NAMD)

Posted on April 9, 2020 by Dr. Donald Kinghorn

On March 19, 2020 I did a webinar titled,
“AMD Threadripper 3rd Gen HPC Parallel Performance and Scaling ++(Xeon 3265W and EPYC 7742)”
The “++(Xeon 3265W and EPYC 7742)” part of that title was added after we had scheduled the webinar. It made the presentation a lot more interesting than the original Threadripper only title! This is a follow up post with the charts and plots of testing results presented in that webinar.

Threadripper 3990x vs 3970x Performance and Scaling (HPL, Numpy, NAMD plus GPUs)

Posted on March 6, 2020 by Dr. Donald Kinghorn

Is 32-cores enough? I had some testing time again on an AMD Threadripper 32-core 3970x and thought it would be interesting to compare that to the 64-core 3990x. In this post I take a comparative look at parallel performance and scaling for HPL Linpack, Python numpy and the NAMD molecular dynamics program.

Threadripper 3990x 64-core Parallel Scaling

64 cores is a lot of cores! How well will parallel applications scale on that many cores? The answer, of course, is, it depends on the application. In this post I look at Amdhal’s Law parallel scaling for HPL Linpack, Python numpy and the NAMD molecular dynamics program.

Note: How To Install JupyterHub on a Local Server

This note describes installing and configuring JupyterHub and JupyterLab on a “bare-metal” server.

AMD Threadripper 3990x 64-core Linpack and NAMD Performance (Linux)

Posted on February 7, 2020 by Dr. Donald Kinghorn

64 cores! The latest AMD Threadripper is out, the 3990x 64-core. I’ve spent the last couple of days running benchmarks and have some results showing raw numerical compute performance using my standard CPU testing applications HPL Linpack and the molecular dynamics program NAMD. The 3990x is a great processor with exceptional performance. Especially for NAMD! (There were some difficulties and disappointments during the testing and I report those here too.)
