What elements of the Linux HPC work are done by SGI versus others in the community?
Neuner: While SGI often focuses on HPC and I/O related kernel issues, it’s not unusual for us to encounter a problem that’s already being worked on or addressed by someone in the community, since many performance, error handling and robustness improvements needed for HPC environments also benefit or affect enterprise environments. However, our access and usage of very large systems also means we are first to find various HPC, scaling or performance related problems. This is due to the fact that one of the best ways to shake out and find problems faster is to “turn up the stress knobs” on a system by using very large system configurations for testing, so systems with large amounts of processors, memory, and I/O are crucial and heavily relied upon for all our kernel development and testing. Also, as community acceptance is critical to all kernel work SGI does, virtually all of the work we do involves collaboration with some subset of the Linux community. HPCwire: Do you think the open so
