First, I'm running FreeBSD 6.1-stable on a small cluster with 6 nodes that contain Tyan motheriboards. These broads have Broadcom GigE NICs that use the bge device. The cluster will be using MPI to possibly shove large data sets through a GigE switch, so I'm trying to determine how best to optimize the transfer. Would DEVICE_POLLING and/or jumbo frames likely methods for enhanced speeds? -- Steve
