 In the end, this script generates a bunch of ''.sh'' files (as many as needed), splits the input files in chunks of ''NPROCS'' within the same node and makes the scripts executable. The only thing needed afterwards is to check that all the parameters are correct and ''qsub'' them. It will use the personal project space (hardcoded, you will need to change this) to create task subdirectories for DMTCP.
