Sorry, I should clarify. The Sun tests are compile failures. The
other failures are likely caused by the tests running longer than the
default time limit (300 seconds). These failures tend to be
intermittent due to system load, file system responsiveness, etc...
and can be ignored for the most part. If I find any actual runtime
failures that aren't load dependent, i.e. issues with the MPI or
serialization libraries, I'll certainly point them out.
If Matthias or Robert can fix the Sun compilation issues, I'll be
