M.2 is a new form of connectivity that allows a SSD to connect directly to the PCI-E bus allowing for theoretical speeds as high as 2GB/s. However, M.2 drives are complicated in that they allow for a variety of physical dimensions, connectors, and even multiple logical interfaces. To help our customers understand the nuances of M.2 drives, we decided to publish this overview of M.2 SSDs.
We’ve been hearing from a regular stream of customers who are making the move from Mac OS X to Windows, and they often have questions about how to perform basic tasks on their new Puget Systems PC running Windows 7 or Windows 8.1. So we created this Start Guide to help them around their new desktop.
OpenFOAM is a collection of programs and libraries for computational fluid dynamics, CFD, and general dynamical modelling with many solver types. It can give linear scaling and excellent parallel performance on Quad socket many-core systems. Read on to see performance on a 40-core Xeon and 48-core Opteron system.
We recently published the article Multi-headed VMWare Gaming Setup where we used VMWare ESXI to run four virtual gaming machines from a single PC. The setup worked great and the article was very popular, but one limitation we found was that NVIDIA GeForce cards cannot be used as passthough devices in VMWare ESXI. We received feedback from some readers that GeForce cards should work in Linux with KVM (Kernel-based Virtual Machine) so we set out to make a GeForce-based multiheaded gaming PC using Ubuntu 14.04 and KVM.
M.2 is a new form of connectivity for SSD drives that allows them to connect directly to the PCI-E bus rather than going through a SATA controller. By bypassing the SATA controller a M.2 drive can have a theoretical maximum throughput as high as 2GB/s which is over three times faster than the 600MB/s SATA is limited to! Unfortunately, temperature and motherboard compatibility is a major issue with these M.2 drives.
I’ve been doing application performance testing on our quad socket systems and I am especially liking the quad Xeon box on our test bench. I realized that I haven’t published any LINPACK performance numbers for this system (that’s my favorite benchmark). I’ll show the results for the Intel optimized multi-threaded binary that is included with Intel MKL and do a compile from source using OpenMPI. It turns out that both openMP threads and MPI processes give outstanding, near theoretical peak performance. Building from source hopefully shows that it’s not just Intel “magic” that leads to this performance … although I guess it really is.
To the best of my knowledge, it’s been at least six years since we’ve written about life behind-the-scenes here at Puget Systems. So we’re going to kick off a whole new generation of newsletters – focused more on the people and less the technology – as we dive into this summer season of 2014. I hope you enjoy this little glimpse of what working at Puget Systems is really like, day to day.
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!
