Hi,

I don't see anything obviously wrong with your setup; there are two
peculiarities that I suggest looking into:
- you seem to be running in a virtualized environment (at least the
hostname indicates this); check if the "flags" /proc/cpuinfo contains
"rdtscp" and if it does not try setting GMX_USE_RDTSCP=OFF;
- your build host is capable only of SSE4.1, try building with
GMX_CPU_ACCELERATION=AVX_256 as the log message indicates; I suspect
that this may not help as an AVX-capable CPU can execute SSE4.1
instructions too;

If none of the above helps, you could try "dropping" to SSE2 and see
if that works.

cheers,

Szilárd
