I'll test 1.2.8 on our Lobo system tomorrow (out today). Primary issue we are seeing there frankly is that some of the tests simply fail when you get up to 16ppn - in one case, it appears that the memory allocated during the test overflows available memory on the node when you get that many procs. So sorting out which tests run at 16ppn and which don't has become a bit of a challenge.

I'll see what I can do, though.

These tests fail with the PGI fortran compiler because they are trying to allocate a 1.5MB buffer on the stack (i.e., they segv before the first executable line of code). Reducing the size of the buffer makes the tests pass.

The size of the buffer was increased by Rolf when he made the intel tests able to be run with more than 64 procs. So I'm pretty sure this is a new failure.

Rolf and I will work out what to do about the intel test, but for 1.2.8, I think we're good to one. It would be good to get one more confirmation from someone else, though.
