Dear all!
in Palabos I am struggling with saving data when running a parallel job on cluster with 100cores.
In the beginning of the simulation I am reading
- the boolean mask form ASCII file
2)loadBinaryBlock(nsLattice, “checkpointTemp.dat”);
loadBinaryBlock(adLattice, “checkpointVel.dat”);
and
at the end of the simulation I have to save all data by doing:
pcout << "writing CheckpointTemp.dat … " << endl;
saveBinaryBlock(nsLattice, “checkpointTemp.dat”);
pcout << "writing CheckpointVel.dat … " << endl;
saveBinaryBlock(adLattice, “checkpointVel.dat”);
Interestingly, sometimes if I resubmit the same job, the task will be completed successfully, more often it however only generates an empty file “checkpointTemp.dat” and the job continues till the walltime is consumed.
I don’t receive any error message, not even when Debug=true.
Anyone’s idea would be greatly appreciated, any comments?
Best,
bohis
