Large-Scale Multiprocessors

Manufacturers

There are several different manufacturers of processors and cabinets that can be used in large-scale multiprocessor (LSM) configurations. For example, Fujitsu's K computer (the number one ranked supercomputer on TOP500's November 2011 list) uses a configuration of 88,128 SPARC64 VIIIfx processors. This means it has a total of 705,024 cores at its use<ref name="k computer"/>. Additional examples of processors used in LSMs can be found in Table 1.

Table 1: Processor Manufacturers
Manufacturer Processor Cores Clock Rate Architecture
Fujitsu SPARC64 VIIIfx<ref name="fujitsu proc"/> 8 2.0 GHz SPARC
Intel Xeon 7500<ref name="intel proc"/> 8 1.733-2.667 GHz Nehalem
IBM POWER7<ref name="ibm proc"/> 8 2.4-4.25 GHz Power ISA v.2.06
AMD Opteron 6100<ref name="amd proc"/> 12 1.7-2.4 GHz Direct Connect 2.0

Please add more info on these processors, e.g., tables for #s of cores, processor type, OS, etc. ... some of this should be available at top500.org.

Table 2: Cabinet Manufacturers
Manufacturer Cabinet Blade Count
SuperMicro MP Superserver 8064B-TRLF<ref name="supermicro chassis"/> 4
HP Integrity Superdome 2<ref name="hp chassis"/> 32
IBM BladeCenter HT<ref name="ibm chassis"/> 12

The course contains nothing about cabinets yet, but it seems like an interesting area. Please explore the tradeoffs in cabinet design, and say who has chosen which design and why.
