blitzdg is an open-source project aiming to implement parallel discontinuous Galerkin (dg) solvers for common partial differential equations systems using blitz++ for array and tensor manipulations and MPI for distributed parallelism.

Running

Currently only supporting running/development on linux systems, primarily ubuntu. Tested with GNU g++ compiler and GNU make.

1. git clone https://github.com/dsteinmo/blitzdg.git
2. cd blitzdg && ./pull-deps.sh
3. make && ./bin/blitzdg (The binary currently doesn't do much).
4. Run unit tests with make test.

Running with Docker

You can also run the build and tests inside a docker container.

1. git clone https://github.com/dsteinmo/blitzdg.git && cd blitzdg
2. docker build -t blitzdg .
3. docker run -t blitzdg

Dependencies

So far:

• blitz++
• SuiteSparse (umfpack)
• metis
• boost
• igloo for BDD-style testing.

Dependency installation is outlined in pull-deps.sh (tested on Ubuntu).

Contributing

We accept pull requests.

If you add code, please write tests using the igloo testing framework that is included as a project dependency.
