Function Documentation

◆ GetOffsetArrayRandom()

IOR_offset_t* GetOffsetArrayRandom	(	IOR_param_t *	test,
		int	pretendRank,
		IOR_offset_t *	out_count
	)

Returns a precomputed array of IOR_offset_t for the inner benchmark loop. They get created sequentially and mixed up in the end. It should be noted that as the seeds get synchronised across all processes if not FilePerProcess is set every process computes the same random order. For a shared file all transfers get randomly assigned to ranks. The processes can also have differen't numbers of transfers. This might lead to a bigger diversion in accesse as it dose with filePerProc. This is expected but should be mined.

Parameters

test	IOR_param_t for getting transferSize, blocksize and SegmentCount
pretendRank	int pretended Rank for shifting the offsets correctly

Returns: IOR_offset_t
