multiprocessor

A computer design in which a single stream of data is broken down by parallel decomposition into smaller chunks and distributed by compilers into multiple microprocessors with shared memory capabilities in order to manipulate the data by parallel processing.

In order to improve the software performance for a CUDA developed application, the programmers must optimize the number of active threads and to balance their memory resources: the number of registers and threads used per multiprocessor, the global memory bandwidth and the percentage of memory allocated to each thread.

In shared-memory multiprocessors with private caches, large cache blocks may also cause false sharing [Lilja 1993], which occurs when two or more processors wish to access different words within the same cache block and at least one of the accesses is a store.
