I have been working on submitting amelia jobs on the cluster service of my university. I cannot get the parallel option to work.

When I invoke amelia with:

amelia(t, m=nmi, ts="year", cs="country",intercs=TRUE,polytime=1,log=vlogs,parallel="multicore",ncpus=4)

only one R process/thread is created. 

Cluster information: 16-core RedHat Enterprise Linux 6 x86_64 server.

Any ideas?

Thank you!
