The SMP parts of the two HLRN-II-2-level installations in Hanover (EDP) and Berlin (TIB) will be provided from five SGI servers with the code name Ultra Violet exist, in which a total of 136 blades, each with two CPU sockets by NUMAlink 5 on a computer with shared memory address space are linked. AlsProzessor ist die Nehalem-Version Beckton mit acht Kernen (16 Threads)vorgesehen, so dass hier also 2176 CPU-Kerne 4352 Threads verarbeitenkönnen. As is the Nehalem processor version Beckton with eight cores (16 threads), so here is 2176 CPU cores can process 4,352 threads. Insgesamt sind in den SMP-Teilen 8,7 TByte RAM vorgesehen, die Rechenleistung soll 21,7 TFLOPS erreichen. Overall, in SMP TByte 8.7 parts of RAM provides the computing power will reach 21.7 TFLOPS.

EX平台太贵,可能不适合HPC
倒是32nm的Westmere-EP看起来不错,也不见得比Nehalem-EX晚多少。 |
