My research group recent purchased a small hyperblade cluster from Appro.com. The system has 6 nodes that are based on the s2881 motherboard with 2 dual-core 2.4 GHz opteron, 16 GB of memory, and 233 GB hard drives. MPICH2 and gfortran appear to work quite nicely on the cluster. The cluster includes a GigE switch, which I hope to replace with infiniband or myrinet in the future. I have no experience with the daughter board you mentioned. -- Steve
