Supercomputing & High Density Racks

At ICC we’ve now deployed the ICC AXIS™ R-725a. Testing on the EPYC 7000 series in our lab showed an increase of ~.1GHz in performance per core on these high core count processors with liquid cooling vs. air. While that does not seem like a big number, it yields a massive performance increase across 32, 64, or 128 cores. ICCRead More

Linux System Load Averages

Helping to Understand the Mystery While load averages are a metric that are widely used for monitoring the health of a system. Quite a few organizations use this metric for capacity planing without fully understanding where the limits should be. But most admins are not sure how to read and or respond to a systems load average. They simply goRead More

The Super-binned 9990XE perfectly illustrates current and future issues with power draw and cooling

The 9990XE made headlines in April of this year for being an Auction-Only part as well as Intel’s fastest most powerful CPU to date. At International Computer Concepts we’ve tested a few of these at their Manufacturer’s settings (5.0GHz, Default voltages) and found that they are nearly impossible to keep stable without a beefier cooler (We normally use a 360mm radiator +Read More

Broadwell-E CPU Benchmarks

Broadwell-E has been released a few weeks ago to consumers, and we have had our hands on some samples previous to that. We would like to share some of the relevant specifications of the BW-E family and detail some of the early results we have seen with them.   CPU i7-6950X i7-6900K i7-6850K i7-6800K Cores/Threads 10/20 8/16 6/12 6/12 Core ClockRead More

ICC Blackhole HPC Workstations

High performance computing can be defined as aggregating computing power in a way that it can solve large scale problems in various fields such as science, business, etc. These can range from the Tianhe-2, the Chinese “Milky Way” supercomputer which has been built to be one of the most powerful supercomputers to run, among other things, physics and astronomy simulations.Read More

HPC Blast from the Past

“It’s awfully early, but I’ll go out on a limb.” These were the first words on the UNIVAC printout of the 1952 presidential prediction, the first time a computer was used to predict the outcome of a presidential election. Now a tradition of the presidential race and the election night broadcast, the UNIVAC, one of the world’s first commercial computers,Read More

Intel's Haswell Xeon E5-2600 V3: The New Server Solution?

At the end of August 2014, Intel took the wraps off its Haswell-E line of CPUs, a significant upgrade over last year’s Haswell thanks to a focus on sheer throughput and performance. Now, the chipmaker is rolling out the Xeon E5-2600 V3: here’s why you should take a look at this new CPU.  The Workhorse, Revisited Intel’s E5 lineup hasRead More

Lessons to Take Away While You're At SC12

An overview of Datanami’s top 20 lessons from 20 different sessions that enterprise IT decision makers should take away from SC12

Supercomputers, Raspberry Pis, and Building a New Universe!

This week has seen a couple very interesting stories in high performance computing. We shared both of them over our Facebook and Twitter channels. The first was cast as quite possibly the cheapest supercomputer you could build… and it used Raspberry Pis and legos! Ever dreamt of owning a supercomputer but didn’t have millions of dollars to spare? Thanks toRead More
