Scaling and the Client Gary Grider’s rule of thumb for HPC 1 Gbyte/sec for each Teraflop of computing power 2000 3.2 GHz processors => 6TF => 6 GB/sec One file server with 48 GE NICs? I don’t think so. 100 GB/sec I/O system in ’08 or ’09 for 100 TF cluster Making movies 1000 node rendering farm, plus 100’s of desktops at night Oil and Gas 100’s to 1000’s of clients Lots of large files (10’s of GB to TB each) EDA, Compile Farms, Life Sciences … Everyone has a Linux cluster these days |
