Hi R team,
I have the HPC, with 10 nodes, and each node with 20 cores in UNIX OS.
my goal is a set cluster to use all machine power, and thy this code:

cl <- makePSOCKcluster(names=c('Host01', ... , 'Host10)
lP <- foreach(j = 1:1000000) %dopar% {Mysimu(j)}

This code is the best way for use all machine power? the code will be run in
200 tasks? 10 x 20?
what is the limited of nodes in makePSOCKcluster?
