SGI Altix 3000 Delivers Performance and Productivity for MCAE Applications

Print version Email story Tweet story
Hardware SGI's Altix 3000 system combines the capabilities of Intel® Itanium® 2 processors, the open-source Linux® operating system, and SGI® NUMAlinkTM high memory bandwidth technology. The system has acheived world record performance on industry benchmarks, but it is performance on real-world applications that matters.

In recent tests using CD adapco Group's STAR-CD software for CFD simulation, the SGI Altix 3000 family demonstrated performance and scalability comparable to some of today's best UNIX systems.

"SGI continues to advance their HPC leadership in CFD with the introduction of the new SGI Altix 3000 server. Working together, SGI and CD adapco have achieved several breakthroughs in parallel scalability with STAR-CD simulations," said Peter S. MacDonald, president of adapco and general manager of CD.

While the single-job application performance demonstrated by SGI Altix 3000 servers is remarkable, it is not the whole story. In many MCAE environments, multiple simulations are queued for execution and must compete with other jobs for resources. The ability to process multiple jobs simultaneously is critical. The combination of single-job turnaround and multi-job throughput is a key measure of productivity for an HPC server.

Multi-job throughput was recently demonstrated for both FEA and CFD software, using customer-supplied models running on an SGI Altix 3000. For FEA, nine jobs were submitted simultaneously to oversubscribe an eight-processor system. The results of these tests were exceptional. The average turnaround for a single job degraded a mere 9% compared to the same job running alone, and throughput capability continues to improve as more efficient I/O schemes are implemented for Linux.

Because of its unique global shared-memory architecture and recent improvements to Linux kernel scheduling, the SGI Altix 3000 family delivers both exceptional single-job performance and multi-job throughput for guaranteed success in MCAE production environments.
