Subject: [OMPI users] memchecker overhead?
From: Brock Palen (brockp_at_[hidden])

Is there a large overhead for
--enable-debug --enable-memchecker?


It sounds like there is and there isn't, what should I expect if we
build all of our mpi libraries with those options, when we run normally:

mpirun ./myexe

vs using a library that was not built with those options?
