According to a blog posting by Sun,

"The Sun SPARC Enterprise M9000 server running 2.52GHz SPARC64 VII processors delivered 2.023 TFLOPS on the Linpack HPC benchmark.

For single servers, the Sun SPARC Enterprise M9000 server outperforms the best IBM Power 595 5GHz POWER6 published result by two times on the Linpack HPC benchmark. This system is the largest that IBM makes for its 5GHz Power6-based servers.

A single Sun SPARC Enterprise M9000 server shows 2.7 times the performance on the Linpack HPC benchmark when compared to the HP Integrity Superdome Itanium 2 system.

The Sun Performance Library was enhanced to take advantage of the SPARC64 VII architecture."

The blog posting highlights several results

• Sun SPARC Enterprise M9000, 64 SPARC64 VII CPUs @ 2.52 GHz
• Sun SPARC Enterprise M9000, 64 SPARC64 VI CPUs @ 2.4 GHz
• IBM Power 595, 32 POWER6 CPUs @ 5.0 GHz
• HP Superdome, 64 Itanium 2 CPUs @ 1.6 GHz
• Sun SPARC Enterprise M8000, 16 SPARC64 VII @ 2.52 GHz

What is the Linpack Benchmark?

The Linpack Benchmark is a measure of a computer’s floating-point rate of execution. It is determined by running a computer program that solves a dense system of linear equations. Over the years the characteristics of the benchmark has changed a bit. In fact, there are three benchmarks included in the Linpack Benchmark report.

The Linpack Benchmark is something that grew out of the Linpack software project. It was originally intended to give users of the package a feeling for how long it would take to solve certain matrix problems. The benchmark stated as an appendix to the Linpack Users’ Guide and has grown since the Linpack User’s Guide was published in 1979. [...read more...]
