SearchEnterpriseLinux: Cray Canada CTO Answers IT Pros' HPC Questions

[ Thanks to Nobody for this link. ]

"Does the advent of high-performance, low-latency, standards-based interconnects put Linux clusters on a more equal footing with supercomputers?

"Paul Terry: Commercial interconnect speeds are improving, but the fundamental cluster architecture and the PCI bottleneck still remain. To compete with supercomputers, systems need to be highly efficient on a broad spectrum of HPC applications, not just a narrow range of codes with minimal communications requirements. They need to employ an architecture that provides high bandwidth, low-latency connections between processors and memory, across the complete system..."
