Hi, You can use multiple types of GPUs in a single run, but it won't be ideal. Also, with Volta GPUs you'll probably be better off also offloading PME which won't scale to more than 2-3 GPUs, so probably you'll not want to use more than 2 GPUs in run with Volta. -- Szilárd On Tue, Aug 28, 2018

[gmx-users] Heterogeneous GPU cluster question?

2018-08-28 Thread Smith, Micholas D.
Dear users (and developers), My sys. admin. is exploring purchasing some more GPU nodes for our cluster and was curious if we could get away with running GROMACS on a cluster that has two different types of GPUs, i.e. 70% of the nodes have 2 p100 gpus while 30% have volta (both have 2 gpu's per
