What I Wish I Had Known

Posted on November 24, 2014 by Brett Nordquist

As part of my job at Puget Systems, I speak with many of our customers at various stages of ownership that range from about a week to a couple of years. These customers often share feedback that we use to improve our products and services. Occasionally customers share what they wish they had done differently when they were configuring their computers. I share this information with our sales team, and figured it might be helpful to those of you considering a new computer today. So in the vein of "If I could do it all over again..." here are a number of items our customers would change if they could turn back time:

Intel Xeon E5 v3 Haswell-EP Buyers Guide

Posted on October 3, 2014 by Dr Donald Kinghorn

The new Xeon E5 v3 Haswell processors are here, all 30+ of them! There is a bewildering variety of clock speeds, core counts, and power usage. There are processors in the new v3 familly ranging from the single socket E5-1620v3 with 4 cores at 3.5 GHz to the dual socket E5-2699v3 with 18 cores at 2.3GHz. How do you make a choice for a new system?! How do these new processors perform when you programs parallel scaling is less than perfect?

LAMMPS Optimized for Intel on Quad Socket Xeon

Posted on August 27, 2014 by Dr Donald Kinghorn

LAMMPS is a molecular dynamics program capable of running very large (billions of atom) dynamics simulations. It is modular with many contributed packages to add extra potential energy functions, atom types etc.. There was recently added a package, USER-INTEL, that adds some nice code optimizations for Intel Xeon hardware. We grabbed the latest source code and did a build with this new code and fired it up on our quad Xeon test system and got very good performance.

Changing Priorities

Posted on August 16, 2014 by Brett Nordquist

I'd never used a Dremel before. But I'd have to learn if I wanted a PC that stood out from all the nondescript beige boxes my friends owned. So I spent the afternoon tracing the pattern on side panel of my Lian-Li aluminum case using a stencil I'd found online. Had YouTube been around at the time, I would have searched to find a Dremel tutorial but it would be few more years before it existed.

Why quad Xeon? 95% of peak LINPACK on 40 cores!

Posted on July 29, 2014 by Dr Donald Kinghorn

Iíve 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 havenít published any LINPACK performance numbers for this system (thatís my favorite benchmark). Iíll 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 itís not just Intel ďmagicĒ that leads to this performance Ö although I guess it really is.

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.

Taking Sides

Posted on June 16, 2014 by Brett Nordquist

Several times a year my father would score Utah Jazz tickets, and being the oldest son, meant I was the one to accompany him to Salt Lake City to watch the games at the old Salt Palace arena. I sat next to my father for the hour-long drive from our home in northern Utah and knew we were getting close when I could see the arena that looked like a large wedding cake. For the next two hours Iíd cheer on the Jazz against their rivals such as the Portland Trailblazers or the Seattle Sonics. The Jazz were my team and my loyalty knew no bounds. I wore Jazz jerseys, collected player cards, and could tell you how many assists John Stockton needed to overtake Magic Johnson as the all-time assists leader.

My brief affair with the tablet

Posted on May 12, 2014 by Brett Nordquist

I recently returned from Las Vegas where I attended an Intel partner event. Over the course of three days, I was able to listen to many speakers give us their predictions for the future of computing. We were presented with demos of fancy all-in-one PCs, sleek new laptops as well as beefy workstations powered by quad Xeons. If Intel was building chips for it, we saw it or heard about it.

4 Things To Do At A Linux Event

Posted on April 28, 2014 by Chris Stephens

This weekend a few of us from Puget Systems made the trip to Bellingham, WA for LinuxFest 2014. Two days of total immersion into the world of Linux and open source. Having recently made the plunge by setting up a native install of Ubuntu on my primary work machine, I thought this would be a great event to soak in the culture and goings-on of the free and open-source software (FOSS) community.

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.

The Continual Rise of the SSD

Posted on April 2, 2014 by Brett Nordquist

Just over a year ago I wrote how Solid State Drives (SSD) were soaring in popularity. At that time we offered a number of SSD models from Intel. But due to production constraints, we were on the verge of adding a few Samsung SSDs to the mix. Around this same time we began fielding a number of requests for Samsung SSDs. Once considered a luxury item, SSDs have moved into the mainstream within the past two years. Our customers tend to be tech savvy and performance demanding to the core. So I wasn't surprised to find widescale adoption of SSDs as I dove into the sales data.

VMware User Group Conference

Posted on April 2, 2014 by Chris Stephens

I spent yesterday attending the Seattle stop of the VMware User Group (VMUG) Conference. It was a totally worthwhile event for catching up with all that is going on in the VMware world. If you didn't already know Puget Systems has been a VMware Partner for quite some time now, we even use a number of their products to run Puget Systems.

Traffic: Puget Systems vs. Netmarketshare

Posted on March 29, 2014 by Brett Nordquist

We thought it would be fun to compare a few of the statistics gathered by Netmarketshare to those we track through Google Analytics for visitors to Puget Systems. According to Netmarketshare, they are the standard in tracking technology usage market share. They have been collecting and analysing data since 1999 and, while not without controversy, are highly regarded in their approach to ranking the most popular operating systems and web browsers.
