I'm currently making an application where I use OpenMPI. I have
successfully compiled Valgrind with MPI support, but I can't seem to get
it to load the libmpiwrap-amd64-darwin.so library. I tried to follow the
user manual section 4.8, bit since there's no LD_PRELOAD variable in OS
X it is not really useful. Instead I tried linking to
libmpiwrap-amd64-darwin.so, and I can run mpirun -np N valgrind
./hello_world without any errors, but the lines
valgrind MPI wrappers 31901: Active for pid 31901
valgrind MPI wrappers 31901: Try MPIWRAP_DEBUG=help for possible options
are not in the output, and Valgrind reports a lot of memory leaks even
though it's just an mpi hello-world program. My Makefile is:
CC=mpicc
CFLAGS=-Wall -O2 -L/opt/valgrind-3.6.0/lib/valgrind #-dylib_file
libmpiwrap-amd64-darwin.so:opt/valgrind-3.6.0/lib/v
algrind/libmpiwrap-amd64-darwin.so
hello: mpi_hello_world.o
$(CC) $(CFLAGS) -lmpiwrap-amd64-darwin mpi_hello_world.o -o hello
clean:
rm -rf *.o hello
