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.
| 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, such as IBM's BladeCenter HT. This particular model uses their CoolBlue technology, a set of tools that allows the user to have greater control over cooling and power use. There are also some standard cabinet frames, such as 19-inch racks, which get their name from the 19-inch panels used in their design. Typically, these racks allow for easy processor/server installation and removal. <ref name="19 inch rack"/>
| 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 |
