Hello Gilles,
I am enclosing all the information you requested.1) as an attachment I enclose the log file 2) I did rebuild OpenMPI 2.1.1 with the --enable-debug feature and I reinstalled it /usr/lib/local. I ran all the examples in the examples directory. All passed except oshmem_strided_puts where I got this message [[48654,1],0][pshmem_iput.c:70:pshmem_short_iput] Target PE #1 is not in valid range -------------------------------------------------------------------------- SHMEM_ABORT was invoked on rank 0 (pid 13409, host=a-Vostro-3800) with errorcode -1. -------------------------------------------------------------------------- 3) I deleted all old OpenMPI versions under /usr/local/lib. 4) I am using the COSMO weather model - http://www.cosmo-model.org/ to run simulations The support staff claim they have seen no errors with a similar setup. They use 1) gfortran 4.8.5 2) OpenMPI 1.10.1 The only difference is I use OpenMPI 2.1.1. 5) I did try this option as well mpirun --mca btl tcp,self -np 4 cosmo. and I got the same error as in the mpi_logs file 6) Regarding compiler and linking options on Ubuntu 16.04 mpif90 --showme:compile and --showme:link give me the options for compiling and linking. Here are the options from my makefile -pthread -lmpi_usempi -lmpi_mpifh -lmpi for linking 7) I have a 64 bit OS. Well I think I have responded all of your questions. In any case I have not please let me know and I will respond ASAP. The only thing I have not done is look at /usr/local/include. I saw some old OpenMPI files there. If those need to be deleted I will do after I hear from you. Best regards, Ashwin.
