Re: [Gems-users] Simulation Time of 16 processors

[Nauman Rafique <nrafique@xxxxxxxxxx>]

You should comment the entire line out. Infact, make sure that only the
following line is uncommented for OPT_FLAGS (other than the architecture
specific flags).
OPT_FLAGS += -O2 -finline-functions -DNO_VECTOR_BOUNDS_CHECKS
-DMULTIFACET_NO_OPT_WARN

That works for me.
