Hi, You mean no matter we use GPU acceleration or not, -npme is just a reference? Why we can't set that to a exact value? On 8/9/2014 5:14 AM, Mark Abraham wrote: You can set the number of PME-only ranks with -npme. Whether it's useful is another matter :-) The CPU-based PME offload and the

Thank you Justin. This is very useful for me. I have a question regarding (and by -1 since CHARMM specifies these values as negative, but Gromacs uses a different convention) I have been wondering what is the Gromacs' convention. Is it just the +ve value after conversion? Date:

That's not what I said You can set... -npme behaves the same whether or not GPUs are in use. Using separate ranks for PME caters to trying to minimize the cost of the all-to-all communication of the 3DFFT. That's still relevant when using GPUs, but if separate PME ranks are used, any GPUs on

Hi, Gromacs is printing out WAYY more data then there is available on my small cluster at UCSC. I just need position data from each simulation time step for the analysis I want to perform. Is there a way that does not involve hacking the source code to set mdrun to print out ONLY the *.xtc
