Hi GMX-Users,
Does anyone have any idea about the problem? Thanks a lot in advance.
I got an error message when using gromacs on 2 processors on the same computer.
The error message is like this:
_________________________________________________________________
splitting topology...
Walking down the molecule graph to make shake-blocks
There are 24390 charge group borders and 26054 shake borders
There are 24390 total borders
Division over nodes in atoms:
21234 21234
-------------------------------------------------------
Program grompp_d, VERSION 3.3
Source code file: splitter.c, line: 121
Fatal error:
Shake block crossing node boundaries
constraint between atoms (21226,21234)
-------------------------------------------------------
________________________________________________________________
I used h-bonds constraints. I tried not
to without constraints and the system can be ran on 2 processors well, but the time-step is small then.
