I'm building HPC tools on a shared cluster, and trying to
"bulletproof" them as much as possible by enabling all the
capabilities and running all the built-in validation tests.<br>
In this case I'm building PNetCDF 1.6.0 using OpenMPI 1.8.5 and
GCC/5.1.0.<br>
Here are some oddities from the "make check" that I ran:<br>
<blockquote><tt>./nf_test -d .</tt><br>

So the tests are listed as passing, but the messages indicate that
an error had occurred.<br>
Are there any global MPI settings that I need to make in order for
these tests to work?<br>
Or did these tests really run OK?<br>
Also when I used the PGI 15.5 compiler instead of the GCC compiler,
I got similar messages on the F77 tests.<br>
But when it started the first F90 test, it hanged.<br>
