Manufacturers
In order to build a large-scale multiprocessor (LSM), you will need to choose the right processors, as well as the most appropriate cabinet(s) to place them in. There are several different manufacturers of processors and cabinets that can be used in 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"/>

| HP | Integrity Superdome 2<ref name="hp chassis"/> | 32 |
| IBM | BladeCenter HT<ref name="ibm chassis"/> | 12 |
