That's true. > However, I think it may be easier in the case of JtR Well, one potential way to do it might be to treat SPEs as a special case of network nodes, once distributed processing support is added. I wish I had the time to play with this. Unfortunately, I don't expect to find the time unless there's commercial demand. Maybe I could approach some IBM folks suggesting that this could be a great example of performance improvement with the Cell. > (I did see in the code some > mention of AltiVec, but that would only exploit the > core of the Cell rather than its SPEs).
