Hi Nicole,
Given the issues you had in the last email, I fear that there might be a
non-standard installation of R, which would be problematic for the parallel
processing part of Amelia, which relies on the "parallel" package that
comes in the standard installation of R. You might want to make sure those
are installed and then try the software again.
You might also check that the cluster allows for multiple cores to be
accessed by the same process. Occasionally, servers will not allow this
type of access.
Hope that helps!
Cheers,
Matt

Dear all,
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!
Nicole
