 | A static ``snapshot'' of the processor during the processing of a vector would show several pieces of data being operated on at one time, and under this view one could say one instruction (a vector add) initiates several data operations (adjust exponents, add mantissas, etc.) and the machine might be classified SIMD. |
| If two or more processors wish to access the same portions of this shared memory at the same time then some arbitration mechanism must be used to ensure that only one processor accesses that memory portion at a time. |
| The interconnection method of the distributed memory system connects the processors in some fashion and if one or more processors wish to access another processor's private memory, it, or they, can only do so by sending a message to the appropriate processor along their interconnection network. |
