NVIDIA CUDA install on CentOS 6.6 [SOLVED]

If you have done a fresh install of CentOS 6.6 or “updated” to it from a 6.5 install and you are setting up NVIDIA CUDA 6.5 you may be having trouble with a failed build of the nvidia-uvm kernel module. Read on for a fix …

POV-ray on Quad Xeon and Opteron

POV-ray is an open source ray tracing package with a long history. It has been a favorite system performance testing package since it’s inception because of the heavy load it places on the CPU. It has had an SMP parallel implementation since the mid 2000’s and is often used as a multi-core CPU parallel performance benchmark on both Linux and Windows.

So lets try it on our Quad socket many-core systems!

Install CUDA and PGI Accelerator with OpenACC

I’m going to walk you through a basic install and configuration for a development system to do CUDA and OpenACC GPU programming. This is not a detailed howto but if you have some linux admin skills it will be a reasonable guide to get you started. We’ll do a basic NVIDIA GPU programming setup including CentOS 6.5, CUDA development environment and a PGI compiler setup with OpenACC. The most interesting part may be the OpenACC setup. OpenACC is a relatively new option for GPU programming and allows for a directive (pragma) based coding model.

Quad Xeon vs Opteron, Zemax OpticStudio

We take a look at Quad Xeon and Quad Opteron performance and parallel scaling with Zemax OpticStudio including an analysis using Amdahl’s Law. Based on this analysis we then make performance predictions for other processors.

NVIDIA GPU Starter DevKit with OpenACC

NVIDIA Tesla K20 plus PGI Accelerator compilers with OpenACC in a package deal with a system. Yes, it’s official. If you’ve wanted to do some development work with OpenACC on Tesla, this is a nice way to get started with a heavily discounted K20 and PGI compiler package pre loaded on a Peak Mini.
