-Note especially the differences in the Windows mpiexec call versus the Linux/Mac - this is required due to the Windows CreateProcess calling directory feature not working for MPI  (fortunately mpiexec allows a working directory flag as shown).

+
+== Example MPI Application - SPECFEM3D ==
+
+As a test application, the seismic wave propagation software SPECFEM3D  (http://www.geodynamics.org/cig/software/specfem3d) has been compiled to work with BOINC as an MPI wrapper application.  There is a demonstration BOINC project at http://qcn.stanford.edu/mpitest with applications for the Linux and the Mac.  The applications are a 5 part job (you can inspect the workunit after attaching to the project) consisting of generating a mesh, database, and running the simulation.
+
+You can build mpich2 and SPECFEM3D using the basic GNU tools such as gcc and gfortran and reference the 'gforker' mpich2 you have built above:
+
+Linux configure

+./configure \
+MPIFC=/home/carlgt1/projects/mpich2-1.3.2p1/bin/mpif90 \

+MPILIBS="-static-libgfortran -L /home/carlgt1/projects/mpich2-1.3.2p1/lib -lfmpich -lmpichf90 -lmpl -lopa"
+}}}
