[gmx-users] There is no domain decomposition error

2019-06-09 Thread Dhrubajyoti Maji
Dear gromacs users, I am studying a system of molten acetamide in GROMACS-2018.3. I have run EM and then NPT equilibration of 5 ns. Here-under, everything is fine but when I try to run a 50 ns NPT production run the following error occurs : There is no domain decomposition for 56 ranks

Hi, Unless you are studying large systems ( 10e6 atoms ) do as Carsten suggests. Get a good Intel or AMD 8 core and the best GPU you can afford. Don’t worry too much about the speed of the CPU either. 3.2 Ghz is fine. p > On Jun 9, 2019, at 6:43 AM, Kutzner, Carsten wrote: > > Hi, > >

Hi, don’t spend all your money on a CPU - for high GROMACS performance the GPU is as important. I would recommend to add an RTX 2070/80 GPU to the workstation, and get a cheaper CPU. This will most likely give you a significantly higher GROMACS performance. See https://arxiv.org/abs/1903.05918
