This is the README for MPI Sessions / MPI Process Sets prototype.

If you have any questions please contact:

Dai Yang [email protected]

Prerequisites

• An MPI distribution, e.g. OpenMPI
• C compiler and MPICC compiler

Building with Makefile

• Edit Makefile, edit CXXFLAGS and LDFLAGS according to the location of MPI sessions / MPI process sets
• Execute

make 

• Our prototype creates the libqmpi.a, which is a static PMPI library intercepting all MPI functions in your application. This means that you have to load our library as a PMPI tool in order to use its functionality in your application. You application msut be linked with our QMPI library, which can be done with the following call. Note you do not need to link against the MPI library if you link to QMPI (NO -lmpi) !!!!!

-lqmpi

• Building the example application:

cd sample
make

Limitations

• Currently only support shared object (.so) based dynamic library tools
• Only supports linux system (and macOS), Windows is not supported.
