Dear Wien2kers,<br><br>I managed successfully k-parallel. I have now to deal with a very big system that definitely needs fully mpi wien2k. The compilation was successful. <br>I can run mpi with lapw0, lapw1, and lapw2. However, lapw2 can run without problem with certain number of PROCESSORS PER MPI JOB (in both cases: fully mpi and/or hybrid k-parallel+mpi). Those certain numbers are 3 and 7. If I try to run with other numbers of PROCESSORS PER MPI JOB, it gives me an message like below. This problem doesn&#39;t occur with lapw0 and lapw1. If any of you could
give me some suggestion of fixing this problem, it would be appreciated.<br><br>[compute-0-2.local:08162] *** An error occurred in MPI_Comm_split<br>[compute-0-2.local:08162] *** on communicator MPI_COMM_WORLD<br>[compute-0-2.local:08162] *** MPI_ERR_ARG: invalid argument of some other kind<br>
