Subject: Re: [AMBER] compiling amber10 with mac intel, ifort/icc and mpi

Thanks dear David, I could manage following your hints and here is my recipe:

# To install Intel C/C++ and Fortran compilers
# install them, they will work for one month but your binaries will
work forever.
# To renew license after a month, go to links above and copy e-mailed
*.lic files in /Users/Shared/Library/Application\

# Mac Osx has openmpi but not with support for Fortran77/Fortran90
# openmpi 1.3.x didn’t work
wget -c
tar xvfj openmpi-1.2.9.tar.bz2
cd openmpi-1.2.9
./configure --prefix=/usr/local CC=icc CXX=icpc F77=ifort FC=ifort
make -j 2 all
sudo make -j 2 install

export PATH=/usr/local/bin:$PATH # IMPORTANT: /usr/local/bin has to
come first to avoid conflict with MPI in /usr/bin and /sw/bin

# Installing AmberTools
tar xvfj AmberTools-1.2.tar.bz2
wget -c
mv -f bugfix.all bugfixAmberTools.all
patch -p0 -N < bugfixAmberTools.all
cd src/
./configure_at icc
make -j 2 -f Makefile_at
cd $AMBERHOME/test; make -f Makefile_at test

# Installing AMBER 10 SERIAL
tar xvfj Amber10.tar.bz2
wget -c
mv -f bugfix.all bugfixAmber.all
patch -p0 -N < bugfixAmber.all
cd src/
./configure_amber -nosanderidc ifort_macosx # ‘-nosanderidc’ is
because ‘divcon’ doesn’t work with ifort
make -j 2 serial
cd $AMBERHOME/test; make test

make clean
#export DYLD_LIBRARY_PATH=/usr/local/lib:${DYLD_LIBRARY_PATH}
export MPI_HOME=/usr/local
./configure_amber -nosanderidc -openmpi ifort_macosx
make -j 2 parallel
cd $AMBERHOME/test
export DO_PARALLEL="mpirun -np 2"
make test.parallel.MM
make test.parallel.QMMM
make test.parallel.EVB

All went fine!

Just some questions more. Divcon is still not ready for inter
compilers? Is is possible to compile divcon alone only with gnu
compilers? Did anyone get PMEMD compiled with Mac intel? From the
README, it seems to be not supported.

Many thanks,
