As of February 1998, Blitz++ is distributed under the terms of the GNU General Public License. Blitz++ development has been opened up (until now, it has been a one-person development effort). Contributions are welcomed.

See blitz-dev.

If you have access to a compiler which might be able to compile Blitz++, please give it a try. More instructions are available on the platforms page.

Also if you are able to compile and run the Blitz++ benchmarks on a new platform, please get in touch.

• FFTs need to be integrated into Blitz++. There are several good packages out there (e.g. FFTW) which we might be able to incorporate.
• More random number generators.
• Currently Blitz++ supports the IEEE/SYSV math libraries only when they are provided by the platform. This seriously hampers portability of programs written using Blitz++. It would be useful to incorporate one of the existing math libraries into Blitz++ so these functions could be available on all platforms.
• Dense matrices and linear algebra. This is being tackled by the sl++ library people, and by the MTL team at Notre Dame (not as part of Blitz++). It would be nice to develop easy ways to move objects back and forth between these libraries.
• Sparse arrays.
• Tensor value classes
• Special value classes for specific problem domains? (e.g. Lattice Gauge Theories, Quaternions)
• Integrating some extended- and arbitrary-precision arithmetic classes.
• Interval arithmetic
• Automatic differentiation
• Parallellism (Threads? shmem? MPI? PVM? Open MP? Data-parallel? Argh!)

If you're a serious fan, you can use this Postscript file to print a Blitz++ poster for your office door. Also looks great on a T-shirt. Be the envy of other geeks. Irritate the Fortran crowd.

The logo shows a snapshot from an acoustic wave simulation implemented using Blitz++. The letters "Blitz++" are a denser medium; if you look carefully you can see wavefronts emerging between the bottoms of the letters.

Please consider posting a short note to the development list before you do major work on the sources. This will give other people a chance to comment on your proposed changes, and decrease the risk that your changes will be somehow incompatible with Blitz++.
