很抱歉问了些琐碎的问题。我正在使用 RMPI 和雪进行集群。调用 makeMPICluster 时没有任何返回。但如果 mpi.spawn.Rslaves() 被调用,它会起作用
# method 1
library(snow)
library(Rmpi)
nclus=3
# no response
cl <-makeMPIcluster(nclus)
# method 2
library(Rmpi)
mpi.spawn.Rslaves()
4 slaves are spawned successfully. 0 failed.
master (rank 0, comm 1) of size 5 is running on:
slave1 (rank 1, comm 1) of size 5 is running on:
slave2 (rank 2, comm 1) of size 5 is running on:
slave3 (rank 3, comm 1) of size 5 is running on:
slave4 (rank 4, comm 1) of size 5 is running on:
