Eh.. I must have missed this thread. Bit late but I think I may know
what is up and perhaps it is actually due to the kernel. forks
possibly given the way Rob described the code he was running.

It is an interesting article, and reminds me of some discussions I've

That's very interesting, Rob. Were the apps compiled using the same
compilers (with the same degree of optimization) in both cases? Were
the time differences actual CPU time of just elapsed time?

Warren,
I'd concur. This application was hugely floating point
intensive. Graphics ops were not an issue for us. The app used only
low-level X11 calls (no Motif, or Xt calls even), so what graphics
there were under OSX had to go through Apple's X11 layer before being
seen. Most of th
I think one needs to distinguish between the OS and the CPU. My
experience with the G5 is that its floating point performance is
between 1.5x and 2x as fast as the equivalent x86. Unfortunately, the

Thanks, Derick.
Although this is a YDL forum, I am afraid to say that there is no
comparison between any linux on PPC and OS X. The former simply
doesn't have the software base that I need. I used to think that it

Good to hear from you Warren!! It's been a long time!!
Glad you liked my analogy.

I might also add that, due to recent announcements from IBM, the
future of the Cell processor is in doubt. In November, IBM announced
that it was canceling the next iteration of the Cell, the one with 32
SPE cores. I would therefore hesitate in investing any time in

Hi,
Anyone that could recommend what
type (title and author) and where to order a suitable book to use to
get a beginner a bit educated in Linux (preferable yellow dog), (I
have some programmer experience from VB, and Pascal)?
I am hoping to get some reading for
Christmas, and some fun with my
