추천 예제
Profile Parallel Code
Profile parallel code using the parallel profiler on workers in a parallel pool.
Profiling Explicit Parallel Communication
Profile explicit communication to the nearest neighbor worker. It illustrates the use of spmdSend, spmdReceive, and spmdSendReceive, showing both the slow (incorrect) and the fast (optimal) way of implementing this algorithm. The problem is explored using the parallel profiler. For getting started with parallel profiling, see Profiling Parallel Code.
Profiling Load Unbalanced Codistributed Arrays
Profile the implicit communication that occurs when using an unevenly distributed array. For getting started with parallel profiling, see Profiling Parallel Code.
