[gmx-users] error in a parallel job

[lulanyuan]

In short. For a certain system A I can calculate it using 1 processor but can not using 2. For other systems I can use any
number of processors (1,2,4 etc) as I like. So what's the problem about system A? 
The error message I got was shake didn't converge. I din't change any condition other than number of processors.
Thanks.
