What does SPEC MPI2007 measure?

0

SPEC MPI2007 focuses on performance of compute intensive applications using the Message-Passing Interface (MPI), which means these benchmarks emphasize the performance of: • the type of computer processor (CPU), • the number of computer processors, • the communication interconnect, • the memory architecture, • the compilers, and • the shared file system. It is important to remember the contribution of all these components. SPEC MPI performance intentionally depends on more than just the processor. SPEC MPI2007 is not intended to stress other computer components such as the operating system, graphics, or the I/O system. They may have an effect in some cases, if the component is exceptionally slow or if there is an unusually small resource bound, e.g. paging delays due to a slow disk or too little memory.

Note that there are many other SPEC benchmarks, including benchmarks that specifically focus on graphics, distributed Java computing, webservers, and network file systems.
