LinuxBIOS, BProc-Based Supercomputer For LANL

Posted by timothy on from the yeah-but-what-about-the-neon-lights dept.

An anonymous reader writes "LANL will be receiving a 1024 node (2048 processor) LinuxBIOS/BProc based supercomputer late this year. The story is at this location. This system is unique in Linux cluster terms due to no disks on compute nodes, using LinuxBIOS and Beoboot to accomplish booting, and BProc for job startup and management. It is officially known as the Science Appliance, but is affectionately known as Pink to the team that is building much of it."

    I wonder why LinuxBIOS hasn't taken off. I've debated ordering one of their "kits." It seems to me the 3 second boot time of LinuxBIOS should be a selling point for some obscure Linux vendor, but no one really offers it yet.

    I really imagine a machine with an 8MB EEPROM/ROM that can be updated as needed, but provides a boot environment and login screen - while spinning the disks in the background. This would make an excellent product.

    Why hasn't anyone done this yet?

    This sounds like some kind of dual-processor rackmount type solution. Why not go all the way and use something like compactPCI? You can fit 21 cPCI blades into 8U of rackspace.

    A standard blade could have up to a couple gigs of ram, a powerpc or p3/p4 cpu, 100BT or 1000BT ethernet, etc, etc.

    You boot the things using bootp/tftpboot and then run linux off a ramdisk.

    We're using cPCI at work to run VoIP softwitches. Currently we're at over a million calls an hour on a wimpy 450MHz processor.
