4620 2.2 GHz quad-core Barcelona, presumably 2-socket nodes, 2GB/core
with pretty agressive IO setup.
if anyone involved in this cluster is reading the list,
it would be most appreciated to see some comments re:
- choice of AMD over Intel is interesting - did you
get to evaluate the 45nm Core2 offerings? decision
based on sustained memory bandwidth?
- what are some details of the storage component?
950 GB/s across 21000 disks (45 MB/s) sounds plausible but
would require a heck of a lot of IB-to-storage ports, no?
thanks, mark hahn.
