POV-ray on Quad Xeon and Opteron

Posted on July 14, 2014 by Dr Donald Kinghorn

POV-ray is an open source ray tracing package with a long history. It has been a favorite system performance testing package since itís inception because of the heavy load it places on the CPU. It has had an SMP parallel implementation since the mid 2000ís 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!

Hyper-Threading may be Killing your Parallel Performance

Posted on July 2, 2014 by Dr Donald Kinghorn

Hyper-Threading, hyperthreading, or just HT for short, has been around on Intel processors for over a decade and it still confuses people. Iím 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.

Install CUDA and PGI Accelerator with OpenACC

Posted on June 27, 2014 by Dr Donald Kinghorn

Iím 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. Weíll 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

Posted on June 18, 2014 by Dr Donald Kinghorn

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

Posted on June 2, 2014 by Dr Donald Kinghorn

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.

NVIDIA HPC future directions

Posted on April 8, 2014 by Dr Donald Kinghorn

Where is NVIDIA heading with High Performance Computing hardware? Ever since Intel announced Xeon Phi Knights Landing as a stand-alone processor integrated at the board level as a full compute unit, I've been wondering what NVIDIA would do along these lines. It just makes sense that they would do something similar since getting the GPU off of the PCIe bus and tightly integrated with plentiful system memory would be a huge step forward for usability and performance. Here's my guess about where NVIDIA is heading.

Compute Performance: Ivy Bridge-E vs. Haswell

Posted on March 13, 2014 by Dr Donlad Kinghorn

How does the Ivy Bridge-E Core i7-4960X (Extreme edition) do against the Haswell Core i7-4770 running the Linpack benchmark? The Ivy Bridge-E 4960X is a great processor -- 6 cores, 4GHz max turbo clock, 4 memory channels, 40 PCIe lanes, big price tag ... However, the humble Haswell 4770 has it's AVX2 and FMA3 secret weapons which are really effective on linear/matrix algebra type of numerical computing problems. ...

New Apple Mac Pro vs Genesis Workstation PC

Posted on March 7, 2014 by William George

By now, most folks have seen Appleís updated Mac Pro - or as I like to call it, the trash can. I kid, I kid! In all seriousness, though, we are often asked how our workstations - like the Genesis line - compare to the hardware Apple has put in the new, miniature Mac Pro. Read on to find out...

The Peak Mini NVIDIA Tesla edition --preview

Posted on February 6, 2014 by Dr Donald Kinghorn

The NVIDIA Tesla accelerator is a well established work-horse for many useful and important High Performance Computing applications and we are happy to be able to provide Tesla acceleration for our "Peak" systems. The developer ecosystem around CUDA is well established, however, at Puget Systems we believe there is new round of developer interest on the horizon that will be catalyzed by the soon to be released 6.x series of the CUDA platform, advances with openACC, new libraries, new hardware, and perhaps significantly, NVIDIA's acquisition of The Portland Group and their excellent compilers and tools for working with Tesla. So, I've loaded up a Peak mini with a Tesla K40 and I'm ready to give Tesla programming a fresh look.

Xeon Phi Developers Starter Kit

Posted on January 14, 2014 by Dr Donald Kinghorn

If you are thinking about getting a system for doing development work targeting the Intel Xeon Phi and you hesitated because of the additional cost of the Intel developer tools you would need then, you should get a system with the "Xeon Phi developers starter kit". The savings on the Intel tools can completely offset the cost of the base system. It's a serious bargain!

How to Select a Traverse Laptop

Posted on December 3, 2013 by Brett Nordquist

Unlike desktop computers that sport large cases, ample power, and generally remain stationary, laptops can be confusing to contrast and compare. Desktop computers are typically much easier to upgrade than laptops so when youíre selecting a laptop, itís a good idea to ensure it includes the level of performance you require from day one. For example, the graphics card thatís used to power games or render complex 3D objects can be simple to upgrade in a desktop computer, whereas you may not have many, if any options to upgrade the graphical performance on your laptop. Swapping out CPUs and drives can be done, but again, you usually have fewer options than with a desktop PC.

Webcams and Privacy

Posted on July 1, 2013 by Chris Stephens

You are staring at the screen, right now, reading this ultra interesting blog post. Did you know that someone could be staring back? There is no doubt that more and more of our customers are turning to laptops for their computing needs. Many people take issue with the integrated webcam and microphone that is on nearly every commercially produced laptop. We get several requests a month to physically remove the cameras and microphones from our laptop orders.
