How to Run an Optimized HPL Linpack Benchmark on AMD Ryzen Threadripper — 2990WX 32-core Performance

Posted on by

The AMD Ryzen Threadripper 2990WX with 32 cores is an intriguing processor. I’ve been asked about performance for numerical computing and decided to find out how well it would do with my favorite benchmark the “High Performance Linpack” benchmark. This is used to rank Supercomputers on the Top500 list. It is not always simple to run this test since it can require building a few libraries from source. This includes the all important BLAS library which AMD has optimized in their BLIS package. I give you a complete How-To guide for getting this running to see what the 2990WX is capable of.

Kabylake vs Skylake for compute on Linux — Linpack on Ubuntu 1610

Posted on by

OK, Intel Core-i7 7th gen Kabylake is out. Of course the first thing I want to do is drop a Core i7 7700K in a new Z270 based motherboard, install Linux and run a Linpack benchmark. You know, GFLOP/s and all that. We installed Ubuntu 1610 with a recent release of Intel MKL and fired up a few Linpack job runs. Read on for the not-so dramatic results.

Intel Broadwell Xeon E5 2600v4 performance test

The Intel Xeon E5 2600 v4 Broadwell processors are finally available. My first Linpack testing with a E5-2687W v4 shows a greater than 35% performance increase over the v3 Haswell version! And, it’s the same price as the v3 version! It’s significantly better than expected.

Xeon E5 v3 Haswell-EP Performance — Linpack

Posted on by

The Intel Xeon E5 v3 Haswell EP processors are here. The floating point performance on these new processors is outstanding. We run a Linpack benchmark on a dual Xeon E5-2687W v3 system and show how it stacks up against several processors.

Compute Performance: Ivy Bridge-E vs. Haswell

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. …
