Hi, I am trying to extend an existing Java-Project to be run with open-mpi. I have managed to successfully set up open-mpi and my project on my local machine to conduct some test runs.
However, when I tried to set up things on our cluster I ran into some problems. I was able to run some trivial examples such as "HelloWorld" and "Ring" which I found on in the ompi-Github-repo. Unfortunately, when I try to run our app wrapped between MPI.Init(args) and MPI.Finalize() I get the following segmentation fault: $ mpirun -np 1 java -cp matsim-p-1.0-SNAPSHOT.jar org.matsim.parallel.RunMinimalMPIExample Java-Version: 11.0.2 before getTestScenario before load config WARNING: sun.reflect.Reflection.getCallerClass is not supported. This will impact performance.
