Sun SPARC Enterprise M9000 Server Surpasses IBM p5 595 and HP Integrity Superdome on Stream Benchmarks
(As of Tuesday, 17 April 2007)
Oracle's Sun SPARC Enterprise M9000 server beat the highest performing IBM p5 595 by over 20 percent and the HP Integrity Superdome by over 45 percent on the Stream COPY benchmark.
The STREAM benchmark is a simple synthetic benchmark program that measures sustainable memory bandwidth (in MB/s) for simple vector kernels. All memory accesses are sequential, so a picture of how fast regular data can be moved through the system is portrayed. Properly run, the benchmark displays the characteristics of the memory system of the machine and not the advantages of running from the system's memory caches.
STREAM counts how many bytes that were read plus how many bytes that were written. For the simple "Copy" kernel, this is exactly twice the number obtained from the "bcopy" convention. STREAM does this because three of the four kernels do arithmetic, so it makes sense to count both the data read into the CPU and the data written back from the CPU. The "Copy" kernel does no arithmetic, but for consistency, counts bytes the same way as the other three.
