Building the Environment
Many hybrid MPI and UPC setups are possible. In our work, we have used the GCCUPC compiler with the Berkeley UPC runtime. The instructions here are focused on building the hybrid setup on an Infiniband cluster. MPI and the BUPC runtime must be build with a compiler that is ABI compatible (i.e. produces binaries that can be linked by) GCC.
WARNING
The current state of the hybrid MPI+UPC environment is in the proof-of-concept phase. We are working to improve the level of support and interoperability, but at present there are many caveats and challenges involved in setting up the environment. Expect things to be broken right now.
GCCUPC

- Untar the source code
- Make a separate build directory
- Run configure from the build directory, no special options are needed
- Build and install GCCUPC
Berlekey UPC Runtime
- Download the BUPC runtime system [2]
- Configure the runtime with the following options:
- ...
- Build and install the BUPC runtime
MPI
Build and install MVAPICH [3]. No special options are needed.
Hydra Process Manager
Build and install the Hydra process manager.
