More Information on Total mPOWER?
Bingo Foo asks: "Many moons ago, I saw an article on some pretty neato sounding PowerPC daughterboards made to work with Intel Linux. To this day, I have yet to see a review of them (Say it ain't so, Ars...), or even a reasonably detailed explanation of how the cross-compiling and job execution work. In a somewhat exhaustive Web search, I found more questions and speculation than answers. All of the specific applications mentioned are rendering and other 'dumb' SIMD processes. It's difficult to tell just how versatile these boards might be. Has anyone shelled out the $6k for one of these things and are they willing to share their experiences with the rest of the world? In particular, I wonder if this might come in handy for some Monte Carlo codes that we run where I work, where raw flops are more important than communication or memory, and the parallelism is MIMD."
"Just an explanation of the programming/compiling/execution process would be nice, and inquiries sent to the manufacturer have resulted in sales-type replies which weren't technically helpful."
These sound a lot like the PowerPC boards that have been used to keep the Amiga alive (well, almost) after the 680x0 chips became old news.
There's a load of links at http://www.suite101.com/linkcat egory.cfm/amiga/4027 if any one's interested.
Basically, the system libraries are all replaced with versions that use the PowerPC for anything remotely complicated, while any older programs just go on using the original processor.
