CFX checkpointing
 
Hi all,

I am trying to run CFX on a supercomputer that has a limit on its queue of one day. Does anyone know if CFX supports checkpointing and how it might be implemented?

I may just have to request a dedicated CFX queue long enough for my jobs.

In CFX V12 you can set a maximum CPU time for simulations. Alternately you can use cron or any other time triggered function to fire off a shell script which calls the stop CFX job script.

Most supercomputers run batch scheduling systems and they also sometimes have built-in functions to halt jobs or do checkpointing at given times.

Thanks Glenn,

They are hopefully going to set up a dedicated queue.
