Intel Performance Estimates Continued
Unfortunately, absolute performance numbers were not disclosed for these benchmarks. The OLTP benchmark is an open source workload based on MySQL that is nearly identical to TPC-C, the gold standard for server performance (along with SAP-2D). LS-Dyna is one of the most popular finite element analysis applications; the benchmark consists of simulating an automobile crash. LS-Dyna is available in both shared memory and distributed versions. Star CD is a computational fluid dynamics package, also available in both MPI and shared memory variants. Both LS-Dyna and Star CD are classic HPC and engineering workloads in commercial use throughout the world.

LINPACK is the ever popular dense linear equation solver used in the TOP500 list. It is also available for shared memory systems and for clusters. While all three Intel systems were simulated at problem size N = 10,000, the AMD score was simply taken from their website.

It is important to recall that these are performance estimates, and as mentioned in the prior page, there are at least three sources of significant variation. They are not perfect estimates, nor are they unbiased, but they do provide valuable information. RWT will be benchmarking Bensley systems, which will give measured results rather than estimated ones.
