[gmx-users] Optimal Hardware for Gromacs

[Alexey Shvetsov]

Hi,

Actualy suppermicro offers 4 socket machines with 12-core amd cpus so you
get 48cores in 1U
GROMACS perform well on such hardware =)

In case of using Infiniband you need IB switch of dual port ib cards (to
connect machines as a 1d torus)
