I am running a large molecule with a large basis set. (It's an expensive
calculation, but I've been given the
resources.) After optimization, the program runs a set of iterations, giving the
message:
3 vectors produced by pass897 Test12= 6.42D-13 1.00D-09 XBig12= 5.97D-13
1.11D-08.
The calculation gets 'stuck' at 3 vectors, even after 3000 iterations, and
several weeks on 24 cores.
1) What do the vectors represent?
2) What to the passes represent?
3) How can I get my job to finish?
