How we check a new system - the common standard benchmarks

The common standard benchmarksBy: Bill Buros.
After we have a new Power7 system installed and configured, we generally will run a set of performance benchmarks on the system to confirm that it's running things as we expect it to.
In a performance lab like ours, we have the luxury of access to SPEC.org benchmarks, the latest IBM XL
On a new system, we will regularly install, build, and run the following "standard suite" of benchmarks.
These four benchmarks are classic compute-intensive workloads which can be run on a single server. Linpack can be extended to run on clusters, and is the benchmark which underlies the Top500 list of supercomputers.
For us, all four benchmarks are intended to run on all of the processor cores and processor hardware threads. We use all cores and hardware threads to focus on the overall capabilities of each system.
Since we take advantage of all of the processor cores and hardware threads, we use the SPECcpu2006 benchmark in a particular way - focusing on what the SPEC.org committee calls the "rate" runs. The SPEC team has a description of this on their website. To save you some time, I copied some of the applicable text here.
