General Development "PathScale announced today that the EKOPath 4 Compiler Suite is now available as an open source project and free download for Linux, FreeBSD and Solaris. This release includes documentation and the complete development stack, including compiler, debugger, assembler, runtimes and standard libraries. EKOPath is the product of years of ongoing development, representing one of the industries highest performance Intel 64 and AMD C, C++ and Fortran compilers." More here.

As most modern compilers, they know to optimize patterns, sometimes with a wider applicability or lesser one.
EkoPath is optimized for HPC workloads (similar with Intel Compiler to one level) and for Amd64 bit only, meaning that they had in some cases opportunities to make the best code.
So at the end: if you have tight scientific code there will be a visible at least 20% speedup over GCC. Also the runtime have more optimized runtime methods, so if the application will use them, can see more benefits, but who knows!?
At the end, will a distro recompile everything to EkoPath? I think that is unlikely: the binaries are a bit bigger as far as I've sow and the speed is not obtained most likely just from this. Will a browser vendor recompile their products to obtain a bit faster layouting? Maybe.
At the end I think you will simply win if you will have to render a thing for a week and worth the price to recompile the raytracer to finish if things will work smooth in 5 days, and one day of you will be free.

Whoa, let's not make such sweeping statements shall we, even in the very small current Phoronix testbed there's a benchmark where ekopath loses out to gcc 4.5 (which is what it was benchmarked against). That said, judging by most of the benchmarks there's potentially alot of performance to be had from this specifically Intel/AMD 64-bit targeted compiler suite.

Also hoping it will have alot better GCC compability than ICC had last time I tried it.

For those of us with Intel/AMD 64-bit systems there could be alot of performance to be had in heavily computational applications, and Pathscale is obviously very set on keeping the bar high, given that ekopath failing to beat GCC or any other compiler in performance is considered a bug by Pathscale.

Gentoo ricers, mount up! ;)
