Please remember to post questions that are detailed enough to answer.
A good start here would be for you to upload your submission script
and R file on some file server and announce links in here with a
description of the problem. Also post the output files.

Possible reasons why your job might die?

1. your cluster administrator has blocked you from using more than 255 cores
2. your cluster only has 97 cores
3. there's a typographical error in your submission script
4. your submission script asks for impossible-to-fulfill memory allocations.
5. your R code has a mistake
