ScaleMP Places Among Top Three Worldwide on Stream Benchmark

vSMP Foundation Achieves Outstanding Sustainable Memory Bandwidth

CUPERTINO, Calif.--()--ScaleMP™, a leading provider of virtualization solutions for high-end computing, today announced record-breaking benchmarking results for x86 systems using the company’s vSMP Foundation™ software. vSMP Foundation claimed the top three results for the STREAM synthetic benchmark program that measures sustainable memory bandwidth (in MB/s) in high-performance computers. The result achieved for STREAM’s Triad function was just over 2.25 TB/s.

ScaleMP benchmarking experts used 64 systems, each equipped with two Intel Xeon X5650 running at 2.66 GHz and 96GB of RAM, aggregated into a single virtual shared-memory system to run the benchmark, receiving top 3 status for this benchmark. The official results can be viewed on STREAM’s website:

"vSMP Foundation aces yet another benchmarking milestone, after having achieved top ranking in SPEC CPU2006 just last month," said Shai Fultheim, founder and CEO of ScaleMP. "These consistently superior results prove yet again the record-breaking performance vSMP Foundation offers its growing list of customers worldwide."

About STREAM Benchmarks

The STREAM benchmark is a simple synthetic benchmark program that measures sustainable memory bandwidth (in MB/s) and the corresponding computation rate for simple vector kernels. This benchmark is specifically designed to work with datasets much larger than the available cache on any given system, so that the results are (presumably) more indicative of the performance of very large, vector style applications.

The STREAM benchmark was created and is maintained by Dr. John D. McCalpin of the Texas Advanced Computing Center at the University of Texas at Austin. It is an independent academic project, and has no affiliation with commercial entities. For more information, please see the website:
