Subject: [AMBER] Why..QM/MM

Why? I did one QM/MM minimization using PM3 level for a metalloprotein. When I specify using only one node (8 CPUs), it's run without any problem. But, when I asked for 4 nodes (4 x 8 =32), it stops after 150 step and doesn't make any more response for more than one day.
Could you tell me why? By the way, I am using sander.MPI of AMBER10 in both cases.
Thanks in Advance
