[Pw_forum] Problem

Hi,
I guess what you mean is the program just got stalled, without any error,
output whatsoever, am I right?
Actually I got the same problem when I do vc-relax. In my case, it runs
well for the first two steps, and then no output, no error any more until
it's killed. 

It seems that this problem is actually related with MPI, and, somehow with
the library you used. I tried to use a serial version of pw, and it runs
OK. Furthurmore, if I abandom MKL, it also runs without stalled. Did you
use MKL to compile this code?

Best wishes,

Chao Cao
