MOC - MPI On Cell
The idea of this project is to implement a message passing library for work on the Cell BE. The main idea behind such an implementation would be to help the programmer by adding an layer of abstraction between the very low level libraries by IBM and give him the possibility to work with an interface he is more familiar with. To achieve this we decided to try to keep very closely to the standard provided by the Message Passing Interface (MPI), so that programmers knowing how to write MPI programmers can easily work with our library. Because of the very special nature of the Cell, it might not be possible to keep 100% true to the standard, but we try to introduce changes only when absolutely necessary and of great benefit, because of some specialties of the Cell's hardware.
For more information take a look into the documentation located in the directory 'document'.
Basic Setup
To be able to compile this library at least Cell SDK 3.0 ( Cell SDK 3.1 would be better) is needed. If the SDK is correctly installed, a simple 'make' should do the job (buildutils provided by the Cell SDK is used). If using Cell SDK 3.0 and the spu-timer-library is selected as time-source on the SPU, the path to the header-files of the spu-timer-library has to be added. Just uncomment the appropriate entry in src/spu/Makefile.
Basic Usage
An application using this library has to add the moc_ppu-library and the spe2-library when linking the PPU-executable. To link the SPU-executable the moc_spu-library is needed and also the sputimer-library when it is selected as time-source and Cell SDK 3.0 is used.
