Re: elmersolver_mpi doesn't exit on completion

For information, while my first tests were with MS-MPI 10.0, I also tried with older version 7.1 and 8.0. The problem remains.

That is very weird.

Re: elmersolver_mpi doesn't exit on completion

I am still investigating the case. Instead of killing the late node(s) via the task manager, I performed a CTRL-C from the console executing the batch. I got the following by mpiexec with 4 nodes: and with 5 nodes: mpiexec aborting job... job aborted: [ranks] message [0] job terminated by the user [...

Re: elmersolver_mpi doesn't exit on completion

To complement my previous report, here is what happened when I tried with 5 nodes this time. During the run, the attached image DuringTheRun.png shows the memory and cpu usage. The second image AfterTheRun.png shows that in this case, 3 nodes did not terminate while we still got printed "Part n...

Re: elmersolver_mpi doesn't exit on completion

Hi I confirm I run the simulations on Windows 10. It seems to me to be an ElmerSolver_mpi issue. When I run with 4 nodes for example, I can see in the windows task manager 4 instances of ElmerSolver_mpi poping up as expected. Once the message "ELMER SOLVER FINISHED" is printed, 3 nodes dis...

Re: elmersolver_mpi doesn't exit on completion

I did not solve the problem yet unfortunately and will definitely post a solution if I find one.

I am surprised that such behaviour apparently relatively common did not get any echo on the forum.

Let us see.

Elmersolver_mpi does not terminate

Hi, I started to run some mpi based simulations in a batch. Also I remarked that when the number of nodes is greater than 2, there is always at least one node that does not terminate. The consequence is that mpiexec waits forever this node and running in a series different cases is impossible. Any i...
