If you want these to run back-to-back you could submit them all with the same job name. On most systems, only one will run at a time.
Or you could have process one submit process 2 at eoj and have process 2 submit process 3 at eoj and son on.
Suggest someone needs to determine why these cannnot all run as one job. . . Something is horribly mis-designed and/or implememted. Several of our smaller jobs process several million per job with no problems. Why is this a problem for your system?
