Head-node is up and serving dhcp, tftp and nfs. It took a while to work around a very broken old PXE stack on the cluster nodes (Tyan MPX). The nodes can boot, but not into anything really useful… memtest. I need to set up some NFS root fs areas for the nodes so that we can boot CentOS on them.
In other news, I got GM2 (Myrinet) compiled for 2.6.18. The kernel module loads and Ethernet emulation seems to work. As promissed I didn’t do any of the cluster integration with Myrinet, just got the kernel module compiled. It looks like OpenMPI supports GM, there is also MPICH-GM. Lustre has a custom driver for MX systems, but as we only have lowly GM boards… we’ll have to operate lustre over IP (over GM) if we want to implement it.
