My practice is to put those flags in the compiler/linker environment
variables. For example:
# ./configure >configure.log 2>&1 \
--prefix=/usr/local/openmpi --with-sge \
CC="gcc -m32" \
CFLAGS="-g -O3" \
CXX="

Can you try running the benchmark with coalescing off? To do that
add the following option to your mpirun line "-mca
