Package BSP

High-level parallelization constructs based on the Bulk Synchronous Parallel (BSP) model.

Parallelization requires a low-level communications library, which can be either BSPlib or MPI. Programs must be run with the bsppython or mpipython executables in order to use several processors. When run with a standard Python interpreter, only one processor is available.

A warning about object identity: when a communication operation transmits a Python object to the same processor, the object in the return list can either be the sent object or a copy of it. Application programs thus should not make any assumptions about received objects being different from sent objects.
