Hi Erik,
Thanks for your suggestion. I was doing a sim run because I get this error when I start a new simulation doing a 'submit' on my cluster "Executing submit command: exec nohup <sim directory address>". Which made me think 'submit' cannot be used when submitting a job to a cluster; rather it can be used only when running a sim on the front end (to hide the output from the terminal).
Anyway, now as I am doing a restart using 'submit' I am getting these messages and then the simulation stops.
Warning: Simulation nsnstohmns_low_resolution_Marronetti already has an active submission. Chaining this submission onto job id 999999
Warning: job status is U
Warning: Job chaining requested but job id 999999 is not in the queue. Its status is U. Aborting submission.
I guess the issue is with the "status is U" part now.
Best regards,
Atul.
