I setup a slurm cluster and I can issue a srun -N4 hostname just fine.

I keep seeing "silent_system2" errors. I've installed slurmR using devtools::install_github("USCbiostats/slurmR")

I'm following the second example 3: https://github.com/USCbiostats/slurmR

here are my files

cat slurmR.R

library(doParallel)
library(slurmR)

cl <- makeSlurmCluster(4)

registerDoParallel(cl)
m <- matrix(rnorm(9), 3, 3)
foreach(i=1:nrow(m), .combine=rbind)

StopCluster(cl)
print(m)

cat rscript.slurm

#!/bin/bash
#SBATCH --output=slurmR.out

cd /mnt/nfsshare/tankpve0/
Rscript --vanilla slurmR.R

cat slurmR.out

You can change this and checkout other slurmR options using: ?opts_slurmR, or you could just type "opts_slurmR" on the terminal.
