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

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

+[binding generic error]

+[bound to everything]
+Open MPI tried to bind a new process to a specific set of processors,
+but ended up binding it to *all* processors.  This means that the new
+process is effectively unbound.

+This is only a warning -- your job will continue.  You can suppress
+this warning in the future by setting the odls_warn_if_not_bound MCA
+parameter to 0.
