blitzdg

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

Build and development support has broadened from linux only to Mac OSX and Windows systems. Tested with GNU make (written to be cross-platform) and g++ on linux/MinGW64/Mac OSX Sierra.

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 (linux) 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)
• LAPACK
• metis
• boost
• igloo for BDD-style testing.

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

Windows Dependencies

The Windows build requires MinGW/MinGW64 and is currently tested in the AppVeyor CI process. There is currently not a Visual Studio/MSVC build.

Run .\pull-deps.ps1 in Powershell (4+ or Powershell Core (pwsh)).

Contributing

We accept pull requests.

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