Dear gulp users and developers,
When I used “mpirun -np 2 ./gulp exampleN”, everything worked well.
However, when I used “mpirun -np 4 ./gulp exampleN” , I got the following errors.
Moreover, “mpirun -np 4 ./gulp exampleN” gived me same outputs as the sample outputs.
Hi Xinbiao Wang
This may not be the error you need to be worried about, since it’s closing a file on 2 of the processes & so may have happened because an error message terminated the run on one of the other processes. So I’d start by looking at the output from the code to see if there is an error there. If there is no error there, you may have an issue with the MPI configuration on your system (not enough processes to run 4 things or something else). Hard to say without access to your system or more information.
Cheers
Julian
