Acknowledgement
Funding for the development of this tool was provided by Sun Microsystems Computer Corporation.
Description
bw_mem_rd allocates the specified amount of memory, zeros it, and then times the reading of that memory
as a series of integer loads and adds. Each four byte integer is loaded and added to accumulator.
The size specification may end with ``k'' or ``m'' to mean kilobytes (* 1024) or megabytes (* 1024 *
1024).
Memory Utilization
This benchmark should move approximately the reported amount of memory.
