Hello everyone,
I am using the "parallel" R package for parallel computation.
Code:
# set number of cores
cl <- makeCluster(8, type = "PSOCK") # Mac/Linux need to set as "FORK"
# pass functions and objects to the cluster environment and set seed
# all the items exported need to stay in the global environment!!
clusterCall(cl, function() { source("xx.R" )})
clusterExport(cl, list("a", "b", "c", "d",
"5"))
clusterSetRNGStream(cl, 1)
While parallel processing, I receive the following warning signs. Do I
need to ignore these signs or do they potentially slow the whole process?
* Warning signs:*
Warning in for (i in seq_len(Ne + echo)) { :
closing unused connection 19
Warning in for (i in seq_len(Ne + echo)) { :
closing unused connection 18
Warning in for (i in seq_len(Ne + echo)) { :
closing unused connection 17
Warning in for (i in seq_len(Ne + echo)) { :
closing unused connection 16
Warning in for (i in seq_len(Ne + echo)) { :
closing unused connection 15
Warning in for (i in seq_len(Ne + echo)) { :
closing unused connection 14
Warning in for (i in seq_len(Ne + echo)) { :
closing unused connection 13
Warning in for (i in seq_len(Ne + echo)) { :
closing unused connection 12
Best regards,
Shah Alam
