Come on guys, after the hints Michael gave us, it isn't that hard to guess which company and what software is behind "Dirndl":
- Intel is very open-source friendly.
- Their full compiler suite costs about $1300.
- The Intel Math-library is known to bring a huge performance boost on multi-core CPUs and multi-threaded programs.
"Contrary to some reader thoughts, this is not an open-source announcement from Intel. "
So this is obviously nothing comming from intel. After all Intel Math libs and their Compiler suite produces much less performance increase on AMD platforms.
I think it's most likely EKOPath4, as others have speculated.
What about performance benefits on crappy hardware like Atom? Or even regular systems (something whose cpu doesn't cost more than a typical laptop)?
It will matter mostly for servers and computing workstations.
Oh and btw - @Michael, if you have this dual quad-core opteron system, would you be that nice and check out if this new magic can speed up some mesa software rasterization on cpu's? Maybe it's a bit silly to do this but it would do a nice proof of concept if this can be used for accelerating some system specific tasks.
