Hi Dumux, I am currently running the boxmodels/2pni test , and I need some clarifications regarding the way DuMuX calls MPI.
I walked through the code of the 2pni test, and I did not see a single reference to MPI (such as a call for MPI_Init), which lead me to understand that the only library which actually calls MPI is Dune, is it correct ? should I assume that most Dumux tests are able to run with MPI? I am using MPICH2 , and when I tried to run 2pni with MPI, I got errors such as : [unset]: unable to decode hostport from 1497 Fatal error in MPI_init: Other MPI error, error stack: MPIR_Init_thread(392): MPID_Init(107).......: channel initialization failed MPID_Init(371).......: PMI_Init returned -1 Please let me know what you think about it, Thank you! Chen
