Hardware and runtime coordinated load balancing for parallel applications

摘要

A method of balancing execution rates for a plurality of parallel program loops being executed concurrently by a processor may include estimating a completion time for each program loop of the plurality of program loops, determining a difference between the estimated completion time of a first program loop of the plurality of program loops and the estimated completion time of a second program loop of the plurality of program loops, and decreasing the difference by adjusting an execution rate of the first program loop.
