Reply To: Example issues on Cluster


Hi Adrian, I’m working in thermal indoor applications with OpenLB libraries, but I have issues with cluster MPI runnings. In my personal computer I don’t have problems loading the checkpoint files even if i’m running on parallel mode, but in the cluster generates the following error:

[prepareGeometry] Prepare Geometry … OK
[prepareLattice] Prepare Lattice …

Primary job terminated normally, but 1 process returned
a non-zero exit code. Per user-direction, the job has been aborted.
mpirun noticed that process rank 24 with PID 0 on node theclimatebox-ubuntu5 exited on signal 11 (Segmentation fault).

As you say, I think that it is necessary to include a patch as soon as possible, in my special case I am working on a server that restarts every 24 hours, so this function is vital for my work.

Thank you for your attention, I will be waiting for your answer.
