This post is a short HowTo on passing Linux kernel boot options during OS installation and persisting them for future system starts
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!
Ryzen 7950x Zen4 AVX512 Performance With AMD AOCCv4 HPL HPCG HPL-MxP
This post is a first-look at performance of the Ryzen7 7950x CPU using the latest AMD compiler release with support for Zen4 arch including AVX512 vector instructions. Performance is tested using the HPC standard benchmarks, HPL (High Performance Linpack), HPCG (High Performance Conjugate Gradient) and the newer HPC Top500 benchmark, HPL-MxP (formerly HPL-AI).
Install Golang In Your Home Directory And Configure VScode
Learning go (Golang) is one of my resolutions for 2023. It looks like a great cross platform compiled language with a straightforward simple syntax with modern features. I have multi-OS projects in mind where I expect it to be ideal. So, I’ll get started …
How To Create A Docker Container For AMD AOCCv4 Compiler Plus Spack Build Tools
AMD has recently released version 4.0 of their AOCC compiler which includes support for AVX512 on the Zen4 architecture. This post details building a Docker image containing the Spack package manager/build system together with AMD AOCCv4.0.0 compilers. This will be used as the build image for multi-stage Dockerfiles that will be used to compile scientific applications and benchmarks with targeted Zen3/4 optimizations. It is the first step in that process.
Ubuntu 22.04 Server Autoinstall ISO
This post is a follow up to How-To: Make Ubuntu Autoinstall ISO with Cloud-init written in Sept. 2021. We will look at changes needed for Ubuntu 22.04.
NVIDIA RTX4090 ML-AI and Scientific Computing Performance (Preliminary)
This post presents preliminary ML-AI and Scientific application performance results comparing NVIDIA RTX 4090 and RTX 3090 GPUs. These are early results using the NVIDIA CUDA 11.8 driver.
AMD Ryzen 7950X Scientific Computing Performance – 7 Optimized Applications
This post presents scientific application performance testing on the new AMD Ryzen 7950X. I am impressed! Seven applications that are heavy parallel numerical compute workloads were tested. The 7950X outperformed the Ryzen 5950X by as much as 25-40%. For some of the applications it provided nearly 50% of the performance of the much larger and more expensive Threadripper Pro 5995WX 64-core processor. That’s remarkable for a $700 CPU! The Ryzen 7950X is not in the same platform class as the Tr Pro but it is a respectable, budget friendly, numerical computing processor.
WSL2 vs Linux (HPL HPCG NAMD)
We’ve been curious about the performance of WSL for scientific applications and decided to do a few relevant benchmarks. This is also a teaser for some hardware-specific optimized application containerization that I’ve been working on!
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.
