For the transport, try:
$ mpirun.openmpi -n 2 --mca btl self,tcp ./printf
yay! this worked. My bare bones test code with that runs flawlessly:
gmulas@capitanata:~/PAHmodels/anharmonica-scalapack$ mpiexec.openmpi
---mca btl self,tcp sample_printf
MPI_Init call ok

Do you have both mpich and openmpi installed ?
yes
can you give the results of "dpkg -l | grep mpich " and ditto for openmpi?
root@capitanata:~# dpkg -l | grep mpich

Can you give me the following:
(1) Does "mpiexec -n 2 ls" work ? any output ?
(2) What hardware do you have ? in particular, any GPU cards, etc ?
(3) What does "ompi_info" report ?
(4) re-run your test program, with the env. variable PMIX_DEBUG=100
(pmix is a new component of openmpi that
(1) How did you execute it ? mpiexec command line , etc?
any way of a number, does not seem to make any difference. Always on
the command line. I tried mpiexec, mpirun, just running the executable
without wrappers (used to work before, if one wanted to run one single
process). I also tried
I cannot reproduce this problem. Can we debug it further ?
(1) How did you execute it ? mpiexec command line , etc?
(2) Can you give the output of :

Any changes to /etc/openmpi/* files or environmental variables

Dear Maintainer,
since the latest wave of package updates (gnu compilers big version switch +
