Hi all:
   I am trying to install GMX 4.6 beta2 on a highly paralleled server.
      with cmake  version 2.8.4
           MPI        openmpi-144 compiled with intel 11.1 compiler
           fftw         3.3.2
           compiler  intel 11.1 gcc 4.1.2
           CPU      Intel(R) Xeon(R)  E5450 with 8cores in one node, with
infinited band node communication.
       with the compling commend:

 # CMAKE_PREFIX_PATH=/home/software/openmpi-144-intel-11-1:/home/dw11-sg007/dying/fftw3
CC=icc  /home/software/cmake-2.8.4/bin/cmake ..
        then I got such a error :
               CMake Warning at CMakeLists.txt:733 (message):
               No C SSE4.1 flag found.  Consider a newer compiler, or
disable SSE4.1 for slightly lower performance.
               CMake Error at CMakeLists.txt:756 (message):
               Cannot find smmintrin.h, which is required for SSE4.1
intrinsics support.
  Is there anybody knowing how to handle such a problem?  Thank you very
much !
