[gmx-users] constraint is serial and parallel runs

Dear All -

Can anyone please explain in simple words why the [LINCS] constraints,
which are stable in the serial run, tend to crash the parallel
simulation. The problem itself can be fixed by using smaller
time-step, but the challenge is to understand the pathway through
which it happens. One basically assumes that interactions are the
same, despite the number of cores involved.

Thank you very much,
