Re: [Pypar-developers] PyPar installation

[Ole N. <ole...@gm...>]

Hi Romesh

When I build pypar on our 64 bit Intel cluster (Ubuntu 9.04) with OpenMPI,
the compile string looks like this:

gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall
-Wstrict-prototypes -fPIC -I/usr/lib/openmpi/include
-I/usr/lib/openmpi/include/openmpi
-I/usr/lib/python2.6/dist-packages/numpy/core/include
-I/usr/include/python2.6 -c mpiext.c -o build/temp.linux-x86_64-2.6/mpiext.o
-fPIC
gcc -pthread -shared -Wl,-O1 -Wl,-Bsymbolic-functions
build/temp.linux-x86_64-2.6/mpiext.o -L/usr/lib/openmpi/lib -lmpi -lopen-rte
-lopen-pal -ldl -lnsl -lutil -lm -o
build/lib.linux-x86_64-2.6/pypar/mpiext.so

and all is well. The same is true on a 32 bit Ubuntu 9.10 system.


Could I ask you to try to run
python compile_pypar_locally.py

That will compile the mpiext.so using mpicc directly (bypassing distutils)
and the compile output should look something like this.

nielso@alamba:~/sandpit/pypar/source$ python compile_pypar_locally.py
mpicc -c mpiext.c -I/usr/include/python2.6
-I/usr/lib/python2.6/dist-packages/numpy/core/include -o mpiext.o -Wall
-fPIC
mpicc -shared mpiext.o  -o mpiext.so -mcmodel=medium
MPI initialised OK


Then you should be able to run the unit tests
mpirun -np 2 python test_pypar.py

Please let us know how you go.

Cheers
Ole
