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!
                                                                                                                                           yours liupeng
