mpich leads to "double free or corrupted" error

Post by Philipp » Thu Apr 15, 2021 12:46 pm

Hello,
I am running wrf.exe on a cluster with slurm and trying to use mpirun results in a "double free or corrupted" error, while using a single thread works just fine.

Hi,
1) To be sure, you did compile WRF with an MPI option (e.g., dmpar), correct?
2) You should have some rsl.error.* files. Take a look at those and see if you see any errors. If not, please attach your namelist.input file, along with all of the rsl* files (packaged together in a *.TAR file), and please let me know the version of WRF you're using.
Thanks!
