HI! everyone!
now, i have already compiled the namd2.7b1 on infiniband. but i find that it is slower than namd2.6.
1> build icc/ifort 10.1.022
2> build the openmpi
./configure --prefix=/hptc_cluster/openmpi-1.2.8-intel CC=icc CXX=icpc --with-openib --without-udapl --disable-openib-ibcm
3> build the charm
./build charm++ mpi-linux-x86_64 smp mpicxx -j32 -O2 -DCMK_OPTIMIZE --no-build-shared --incdir=/opt/intel/cce/10.1.022/include --libdir=/opt/intel/cce/10.1.022/lib --incdir=/opt/intel/fce/10.1.022/include --libdir=/opt/intel/fce/10.1.022/lib
4> build the charm
in this route, no fatal errer occure to terminate the compileing . but the final performance is very not good. or it is very bad.
what's worry?
any help is appreciated!
thanks!
