GTC23  Notes And Selected Sessions

NVIDIA GTC 2023 was outstanding! To say that about a virtual conference tells you how much I value it. This post is largely a catalog of the talks I found interesting along with titles that I think will be interesting to a larger audience and my colleagues at Puget Systems.

Problems With RTX4090 MultiGPU and AMD vs Intel vs RTX6000Ada or RTX3090

I was prompted to do some testing by a commenter on one of my recent posts. They had concerns about problems with dual NVIDIA RTX4090s on AMD Threadripper Pro platforms. I ran some applications to reproduce the problems reported above and tried to dig deeper into the issues with more extensive testing. The included table below tells all!

UPDATE v0.2 NVIDIA GPU Powerlimit Setup

This is just a short post to announce a more usable version of the NVIDIA GPU powerlimit setup script that I released a few months ago. This update to version 0.2 uses an interactive mode to set GPU powerlimits and optionally setup a systemd unit file to set these limits on subsequent reboots.

Molecular Dynamics Benchmarks GPU Roundup GROMACS NAMD2 NAMD 3alpha on 12 GPUs

We have a new collection of GPU accelerated Molecular Dynamics benchmark packages put together for GROMACS, NAMD 2, and NAMD 3-alpha10. (The benchmark packages will be available to the public soon.) In this post we present results for,
– 3 applications: GROMACS, NAND 2 and NAMD 3alpha10,
– 8 MD simulations,
– 12 different NVIDIA GPUs,
– 96 total results.

LTSP Configuration for Benchmark Platform of Diskless Workstations

In this post we look at using a testing Lab of Windows systems as a benchmarking platform for Linux scientific application using network boot with nfsroot and home mounts. Linux is boot on the systems “diskless” leaving the Windows installs untouched. LTSP turned out to be a great time saver for setting up the configuration.

NVIDIA GPU Power Limit vs Performance

This post presents testing data showing that power-limit reduction on NVIDIA GPUs have give significant benefits for both high wattage and lower wattage GPUs. Power-limit vs Performance data is presented for 1-4 A5000 and 1-4 RTX3090 GPUs.

NVIDIA GPU Powerlimit Systemd Setup Script

In this post I am referencing a Bash shell script I recently put together for setting up automatic NVIDIA GPU power-limit lowering at system boot. This allows a reliable way to configure and maintain multi-GPU systems for stable operation under heavy load.

Self Contained Executable Containers Using Enroot Bundles

NVIDIA Enroot has a unique feature that will let you easily create an executable, self-contained, single-file package with a container image AND the runtime to start it up! This allows creation of a container package that will run itself on a system with or without Enroot installed on it! “Enroot Bundles”.

NVIDIA 3080Ti Compute Performance ML/AI HPC

For computing tasks like Machine Learning and some Scientific computing the RTX3080TI is an alternative to the RTX3090 when the 12GB of GDDR6X is sufficient. (Compared to the 24GB available of the RTX3090). 12GB is in line with former NVIDIA GPUs that were “work horses” for ML/AI like the wonderful 2080Ti.
