vi 发帖数: 309 | 1 What's the difference between the two?
Looks that they support the same set of operations with same restrictions. | b**g 发帖数: 335 | 2 不完全一样
两者实现的算法也不同
MPI_Scan绝对是线性的
MPI_Reduce可用binomial tree或Rabenseifner算法实现,速度较快

| vi 发帖数: 309 | 3 Thank you, but what do you mean by 'linear'?
MPI_Scan is prefix_sum, should be very easily parallized?
