Re: C question
I'm actually programming for one arch (PS3 Cell Processor to be exact) so that doesn't bother me.
It does appear to be working so thanks

I've been able to reach arround 30 billion MD5 hashes per second using the 6 SPU cores on the PS3...I'm trying to make it even better still..

What's your practical application? Cracking apache htpasswd files?

30B MD5 hashes per second over 6 cores means 5B hashes per second per core. I suppose I could believe that the PS3 could do 5B CPU instructions per second per core, but I don't buy that it can do 5B MD5 hashes (even simple ones) per second. I doubt even the memory bandwidth is sufficient for that amount of computation.
Did you mean million?
