计算并行程序的经过时间和cpu时间

Question

All:

I have a parallel program which has three processes. Each process is running on a different machine. I would like to calculate the elapsed time and CPU time of the parallel program. Is the following formula correct?

Elapsed time = the maximum elapsed time of three processes

CPU time = the sum of each process's CPU time

Thanks
