[FLASH-USERS] Problem with restart: almost empty output files

[Mattia Cipriani]

Hi all,

I am running a 3D simulation derived from LaserSlab.
The simulation cannot be run entirely with a single run for the time limit on the queue, then I stop the simulation by setting wall_clock_time_limit appropriately and FLASH outputs a checkpoint file about one hour before the time limit of the queue on the cluster.
When I restart the simulation from this checkpoint file, everything goes fine but the first about 10 output plot files have a size of 110 kB, compared to the size of the files from the first run of 471 MB. As a confirmation of this, from the flash log file (attached) I can see that the plot file stays open for only a couple of seconds in the second run, compared to three minutes of the first.
The size of the checkpoint file used for restart is normal.
I also tried to free up some space on the storage on the cluster, even though I check that I am far from my quota limit. And in fact this did not solve the issue.

What could be the problem?

Thank you in advance.
Best regards,
Mattia
