[gmx-users] replica exchange and gpu

[Jacopo Sgrignani]

Dear all 
I would like running a replica exchange simulation using gromacs and gpu.
However when I Try to run the calculation I get this message

mdrun -multi is not supported with the thread library.

how do I compile gromacs ?
Could anyone confirm me the possibility to run 8 replicas on one GPUs or do I need 8 GPUs.

Thanks 

Jacopo
