[execve error]
25+
Open MPI tried to fork a new process via the "execve" system call but
26+
failed. Open MPI checks many things before attempting to launch a
27+
child process, but nothing is perfect. This error may be indicative
28+
of another problem on the target host, or even something as silly as
29+
having specified a directory for your application. Your job will now
30+
abort.

[binding not supported]
38+
Open MPI tried to bind a new process, but process binding is not
39+
supported on the host where it was launched. The process was killed
40+
without launching the target application. Your job will now abort.

[binding generic error]
46+
Open MPI tried to bind a new process, but something went wrong. The
47+
process was killed without launching the target application. Your job

[bound to everything]
56+
Open MPI tried to bind a new process to a specific set of processors,
57+
but ended up binding it to *all* processors. This means that the new
58+
process is effectively unbound.
59+
60+
This is only a warning -- your job will continue. You can suppress
61+
this warning in the future by setting the odls_warn_if_not_bound MCA
62+
parameter to 0.

[slot list and paffinity_alone]
69+
Open MPI detected that both a slot list was specified and the MCA
70+
parameter "paffinity_alone" was set to true. Only one of these can be
71+
used at a time. Your job will now abort.
