Last I checked, the CUDA stuff requires proprietary software and drivers. Not an especially good fit for GNURadio. Cell BE has the advantage of being exceptionally easy to target: I was able to get a project I work on (http://www.celt-codec.org) running entirely on the SPU of a PS3 within about 10 minutes of installing the SDK. (Okay okay, I spent a little time reading the SDK docs while the ISO downloaded and installed) On the negative side, the only way mortals can access a Cell BE is by using a PS3. This is silly and hard to justify to the applicable finical controller (i.e. spouse or boss). Being able to slap in a video card is nice, especially since you could plug several into a system. Hopefully the Intel Larrabee (http://en.wikipedia.org/wiki/Larrabee_%28GPU%29) will combine these qualities and we'll have something which is open, easily programmable, scalable, and affordable. _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
