New World Record SPECint_rate2006 Sun Ultra 40 M2 Workstation

Thursday Nov 16, 2006

The Sun Ultra 40 M2 Workstation demonstrates a new World Record integer throughput performance for all x86 systems, sets a new world record on the new and improved SPEC cpu benchmark called "SPECint_rate2006." It fixes things like SPECint_rate2000 has/had floating-point applications in the integer suite, whaaaat? yes strange but true.

The Sun Ultra 40 M2 delivered the SPECint_rate2006 score of 48.8, using Solaris 10 and Studio 11 combination. Sun's Opteron beats Woodcrest by 7%. As you can see below 'Peak' means you add a few more compiler flags. I guess Woodcrest didn't have any others to try on Woodcrest or maybe they saw no improvement so they avoided publishing? Anyone know?

Benchmark Description

SPEC CPU2006 is made up of two suites of benchmarks, CFP2006 and CINT2006. CFP2006 targets floating-point performance, while CINT2006 targets integer performance.

Each suite has two different measures. First is the CPU measure, which is the performance on the suite as a single stream. This can be either a single thread or automatic compiled parallel run. This measure is further defined by base and optimized runs. Base uses the same compiler flags for all kernels, where optimized is allowed to use different compiler flags for each kernel. Results are compared against a baseline system run that was standardized by www.spec.org.

The second measure is Rate. I think this one is a LOT more important. It is a measure of how many CPU measures can be run at a time. Typically, it is run as n processes on n processors or threads. It shows how well the same job mix can run on a system under some load. It also is run as a base and optimized set of results. "Rate" is what you use for any mult-threaded workstation and all servers.
