Thanks Sean. I run into trouble when installing the packages. After invoking R, I try to install the packages - with mixed success:
install.packages("parallel")
Installing package into ?/nv/dom/R/x86_64-unknown-linux-gnu-library/3.1? (as ?lib? is unspecified) Warning message: package ?parallel? is not available (for R version 3.1.0)

Warning message: In install.packages("Rmpi") : installation of package ?Rmpi? had non-zero exit status The packages ?foreach? and ?snow? installed ok, although i?m not sure how well snow will do, given that I get errors on trying to install Rmpi. Any suggestions for these? Or where I should go from here? thanks!

Hi,
I am trying to get started on our Moab cluster. My pbs script looks like:
======= test.pbs ============
#!/bin/sh
#PBS -N job_name
#PBS -l nodes=1:ppn=3
#PBS -q debugq
module load R
cd $PBS_O_WORKDIR
mpirun -rmk pbs R --slave CMD BATCH ./test.r
======== test.r ============
print('hello world')
You'll need to change "test.R" to use something like the parallel, foreach, BiocParallel, or other parallel processing package. Just running using MPI will not help you here. Sean
To submit my job, I use:
msub test.pbs
When I execute this, the .Rout file contains 'hello world' and everything
looks ok. However, how can I get each processor to write out something
like:
'hello world from 1'
'hello world from 2'
'hello world from 3'
How can I get the processor number as an input to the r script?
many thanks!
