Building The MareNostrum COTS Supercomputer 187
karvind writes "IBM Power Architecture Community Newsletter has a story about making a supercomputer (Number 4 on top 500 list) from easily available components (like BladeCenter and TotalStorage servers, 970FX PowerPC processors, and Linux 2.6). A joint venture between IBM and the Spanish government, it is named MareNostrum: the Latin term meaning 'our sea.' Peaking at 40 TFlops, the beast consists of 2,282 IBM eServer BladeCenter JS20 blade servers housed in 163 BladeCenter chassis, 4,564 64-bit IBM PowerPC 970FX processors, and 140 TB of IBM TotalStorage DS4100 storage servers."
