Re: Porting Octave to IBM Cell Processor

[Shai Ayal]

For most of the operations you talk about, octave uses external
libraries (e.g. fftw for fft, lapack for matrix ops), so the place to
start is to optimise these libraries for the Cell. I don't think this
is an easy task. However chances are that this was already done by
someone (these are pretty popular libraries), so your task will
degenerate into getting octave to compile on the Cell with these
libraries.

In any case I would start bu downloading the source and trying to
compile it -- ust to see where you're standing
Good luck
