Got it. Thanks. It's a PHP memory overload issue.
(Apparently I didn't look far back enough in the httpd
error_logs.) See below.

Some missing results are in mttdb_debug_file.16.txt (and
17.txt), which are the largest .txt files of the bunch. 8
variants isn't that much, but maybe it causes a problem when
there's lots of stderr/stdout? I'm surprised
submit/index.php barfs on files this size:

We'll have to somehow be more efficient on these loops.
E.g., line 1559:

   foreach (array_keys($_POST) as $k) {

Maybe if we broke $_POST up into multiple parts (e.g.,
$_POST_1, $_POST_2, ... $_POST_N)? Maybe we could do
something more efficient than array_keys here? I'm not sure.

The only workaround on the client side would be to break up
the runs. Maybe do a single MPI Install at a time? Do
ompi/gcc then ompi/intel-9.0 as seperate invocations of the
MTT client.

Sorry :-(
