Testing NWChem installation for correctness

Thanks for the help.

I have been running some of the test from the QA directory, then parsing the output and diff them. So, for instance 6.8 compiled with Intel 17 would produce some fails, but also 6.6 patched and compiled with Intel 17. All those results are also different from the output produced with 6.6 and Intel 16...

So, the question is, should I assume that the last version (6.8) compiled with an up to date compiler (Intel 17) would produce the right (or close to) outputs? Here I show part of the output of
diff -w autosym.6.8.out.nwparse autosym.out.ref.nwparse

How serious is this? If so, what can be done?
