Subject: [overture] Parallel Overture on Mac
Reply-To: "overture@xxxxxxxxxxxxx" <overture@xxxxxxxxxxxxx>
Hi Ramesh,
I managed to build Overture on the Mac. There were a few odd things.
0) It appears that openmpi is on the mac by default in /usr, I had not
known that.
You can also use the openmpi and mpich or lam mpi from macports.
1) the configure line for A++P++ is:
./configure --prefix=`pwd` --without-PADRE --disable-shared --disable-
mpirun-check --enable-PXX --with-CC="gcc -I/usr/include/malloc" --
with-
CXX="g++ -I/usr/include/malloc" --with-mpi-libs="-lmpi_cxx -lmpi"
2) To build A++P++, use :
make MAKE=make install
3) make sure you have a parallel build of HDF5
4) configure Overture using something like:
./configure darwin parallel useHDF5 FC=gfortran
5) Now you need to fix the PFLAGS variable in $Overture/GridFunction/
Makefile in order to add -I/usr/include/malloc
6) In the primer directory Makefile, eliminate the -Wl-weak-
framework,VecLib option from all the make variables
7) Fix ParallelUtility.C, the bool version of broadCast should be:
void
broadCast( bool & value, const int & fromProcessor )
{
#ifdef USE_PPP
if( Communication_Manager::Number_Of_Processors==0 )
return;
int tmpValue = value;
MPI_Bcast( &tmpValue, 1, MPI_INT, fromProcessor, MPI_COMM_WORLD);
value = tmpValue;
#endif
}
8) Now you should be able to build Overture and also build the
examples primer/pppWave and primer/pwave
I was able to build and run pppWave and pwave with two MPI tasks on my
mac laptop. We are working the fixes
into the next release.
Let me know how this works!
