Hi, I am having trouble with running gromacs with a large system. I am trying to use several processors for the md. The error is a memory allocation error and it might be due to low RAM or large no of particles. I want to know the detailed memory usage of mdrun ie say for N atoms how much memory does the master node need and then also whats the memory requirement for the other nodes. By master node i mean the node that does the domain decomposition calculation etc during the start of mdrun. A webpage which describes the memory requirement at various stages during mdrun will be very helpful.
Thank you, amit
