That's great! When are we going to see a bump in the statistics?
The Cell processor comes with 8 floating-point "co-processors",
How does this help RC-5?
Can you explain a little bit what was the code implementation
strategy?

Dear friends,

The PlayStation 3 is here. Perhaps you know somebody running  
Folding at Home on theirs? We couldn't sit idle. Our crack team of  
programmers has ported dnetc to the PlayStation 3 platform, complete  
with optimized RC5-72 assembly code for record-breaking speed.

We really mean it: we have measured the PlayStation 3 processing  
RC5-72 work units at close to 170 Mkeys/sec, easily making this the  
fastest hardware platform our client has been ported to.  This is  
more than 22 times faster than a computer with a Pentium 4 processor  
running at the same clock speed as the PS3's Cell processor. Although  
OGR is enabled on this build, work on optimized OGR cores is in  
progress; expect a suboptimal rate of about 17 Mnodes/sec if you  
choose to run OGR.

You are welcome to download this pre-release client from our web site  
at http://www.distributed.net/download/prerelease.php. Please note  
that this client expires in 2 weeks, when we plan to release a new  
version including optimized OGR cores.

We thank you for your continuing support. Moo! ]:8)
