Hi there,
I am using the latest cvs on hector cluster (http://www.hector.ac.uk/) and normally I set the
simulation to 64 cpus and -dd 4 4 4. This gives to me a good performance for a simulation with ca.
200,000 atoms (6ns/day with dt=2fs).
How many cpus the new gromacs may scale-up? do you have any optimised parameters? Do you think that
128 cpus can perform better in speed?
thanks in advance
regards
andrea
