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

Like processors, different manufacturers offer varying cabinet/server types. For example, IBM's BladeCenter HT includes their CoolBlue technology, a set of tools that allows the user to have greater control over cooling and power use.
