Rendering and HPC Benchmark Session Using Our Best Serversby Johan De Gelas on September 30, 2011 12:00 AM EST
Introduction to Server Benchmarking
Each time we publish a new server platform review, several of our readers inquire about HPC and rendering benchmarks. We're always willing to accommodate reasonable requests, so we're going to start expanding beyond our usual labor intensive virtualization benchmarks. This article is our first attempt. It was a bumpy ride, but this first attempt produced some very interesting insights.
The core counts of modern servers have increased at an incredible pace, making many benchmarks useless if we want to assess the maximum throughput. Just three years ago, we could still run benchmarks like Fritz Chess, Winrar, and zVisuel to satisfy our curiosity. We also performed real-world benchmarks like MySQL OLAP on our octal-core servers. All these benchmarks are pretty useless now on our 48-core Magny-Cours and 80-thread Westmere-EX systems. The number of applications that can really take advantage of the core counts found in quad- and even dual-socket servers continues to get lower and lower.
Most servers are now running hypervisors and virtualization of some form, so we naturally focused on virtualized environments. However, many of our readers are hardware enthusiasts, so while we wait for the new server platforms such as Intel's Romley-EP (Sandy Bridge EP) and AMD's Interlagos (Bulldozer) to appear, we decided to expand our benchmark suite. Our first attempt is not very ambitious: we'll tackle Cinebench (rendering) and Stars Euler 3D CFD (HPC). Both are quick and easy benchmarks to perform... or at least that'ss what we expected going in. On the plus side, our testing results are a lot more interesting than we imagined they would be.
