      Mark:
Try '-matmatmult_via scalable' first. If this works, should we set it as

So the process is currently using 2.5GB - and then made a malloc
request for 650MB - and this failed?
Yep, large but not garbage.

How many 'tasks-per-node' are you using? Perhaps you need to reduce this
number?
Treb has run this job before and I think this code has been touched
recently ... I suggested that Treb try -matmatmult_via scalable

We are getting this error on Edison. This problem has run before. This
is
using maint from last week.
I recall there are low memory options for mpiptap. I don't think we are
using them.
Thanks,
