Detailed Description

An Array of MPIOutputBuffers.

Allocates contiguous memory space necessary to hold the mpi serialized spike data prepared for sending for all of the MPIInputBuffers in the array, and then gives equal-sized segments of this memory pool to all of the mpi input buffers. MPI input buffers then use this memory segment to store the outgoing serialized mpi data.

Constructor & Destructor Documentation

MPIOutputBufferVector::MPIOutputBufferVector	(	int	numBuffers,
		vector< gl_engineid_t > &	engIDs
	)

Constructs vector of buffers with size numBuffers, and segment buffer block size of buffer_size.

Parameters:

	numBuffers	the size of the array of mpi output buffers.
	engIDs	array giving the global engine ids of local single thread engines.
