Dear all,

When trying to run any of my firedrake codes, I get the MPI error below. This is the case even if my script only contains the line "from firedrake import *". I have recently modified my PATH and I expect that the error comes from there, as mpi worked previously. My current PATH is:

/Users/mmfg/firedrake/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin:/Library/TeX/texbin

Any hint ?

Thanks a lot,

Floriane

PMIx has detected a temporary directory name that results

in a path that is too long for the Unix domain socket:

    Temp dir: /var/folders/7h/wbj8xp7n3g5cfbr32ctcmwzcy3jf53/T/openmpi-sessions-1010350243@math-mc1096_0/63253

Try setting your TMPDIR environmental variable to point to

something shorter in length

It looks like orte_init failed for some reason; your parallel process is

likely to abort.  There are many reasons that a parallel process can

fail during orte_init; some of which are due to configuration or

environment problems.  This failure appears to be an internal failure;

here's some additional information (which may only be relevant to an

Open MPI developer):

  orte_ess_init failed

  --> Returned value Unable to start a daemon on the local node (-127) instead of ORTE_SUCCESS

[math-mc1096.local:541] Local abort before MPI_INIT completed completed successfully, but am not able to aggregate error messages, and not able to guarantee that all other processes were killed!
