We have had some customers report that the power LED on the on the Fractal Design Define R4 is too bright for their liking. This is a video that will show you how to disable the power LED. This video also shows you how to remove an angled acrylic fan holder.
The first computer I purchased arrived at my home with two operating systems: DOS and Windows 3.1. Most full-fledged programs ran in DOS, including nearly every game in the early 1990s. Besides pool, the game I played most during my college years was called Links Golf which ran in DOS. Without Links I’m convinced my GPA would be at least a half grade higher. I offset my Links addiction by installing WordPerfect for DOS which allowed me to write reports from home instead of the school’s computer lab
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!
As powerful as modern PCs are, sometimes it feels like a waste having just a single person using a PC at a time. By using various server virtualization technologies including virtual machines and PCI passthrough, we created a multi-headed gaming PC that allows up to four users to game on one physical PC at the same time.
Hyper-Threading, hyperthreading, or just HT for short, has been around on Intel processors for over a decade and it still confuses people. I’m not going to do much to help with the confusion. I just want to point out an example from some testing I was doing recently with the ray-tracing application POV-ray that surprised me. Hyper-threading dramatically lowered the performance on a multi-core test system running Windows when running POV-ray in parallel.
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.
Does your clock constantly drift to an inaccurate time/date? Our guide will help you hunt down the source of the problem and fix it!
Virtual desktops with NVIDIA GRID offer a great way to provide users with tons of computing performance without the need for each user to have their own individual PC. We took the time to setup and use a virtual desktop for a variety of applications to see if we think virtual desktops will be the future of computing or if they will simply be another niche technology.
With up to 64 cores and 1TB of memory, the new workstations from Puget Systemsoffer not only extreme performance, but also excellent cooling and quiet operation. Puget Systems has been providing quad socket workstations for years now. Today, we refresh that product with a new duo of quad socket workstations that offer even more capacity, better
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.
Puget Systems builds custom workstations, servers and storage solutions tailored for your work.
