PathScale Open-Sources The EKOPath 4 Compiler Suite
It would appear that Phoronix jumped the gun a bit here. So far, there's still nothing on the PathScale site and while a trusted source has told me that the release is still on for now, I'm kind of worried about the effect that the early leak will have...
Michael jumped the gun two weeks ago with all his "hinting". I wonder who will seriously give this site news under embargo again?
They are big differences in performance.
Even if the applications have been well chosen, I would never expect to see such differences by just using another compiler.
Maybe this should be considered as bugs in GCC (it must obviously do something wrong to see such a difference).
That would be very interesting to compare compilations options, and to see how that works on different configurations as well.
And why not using Fedora 15 with GCC 4.6 to perform benchmarks?
It's a bit more bleeding edge than Ubuntu.
I think one of the main problems is even though OpenMP is supported in GCC very few programs utilise it's features. I think PathScale have found ways of optimizing even with out OpenMP syntax
I would be curious to see the results of GCC running with the -ftree-parallelize-loops flag
