I just switched from the version 3.3 to 4.0. It turned out that the 4.0
version does not allow to run a parallel simulation of my protein in vacuum.
The protein consists of 2 chains and 4 separated (no bonds with chains)
co-factors. For vacuum simulation 'pbc=no' which makes to use particle
decomposition option "-pd" of mdrun. In this case the automatic particle
distribution over the nodes leads to the error:
"Fatal error:
Shake block crossing node boundaries
constraint between atoms (11191,11193)"
In the previous version 3.3 I used manual balancing with the "-load" option
to avoid the problem. In the current version 4.0 I did not find anything
similar for the particle decomposition. Is there a way to run parallel
simulations of the protein in vacuum?
Thanks
