Intel compiler "crippling performance" on non-Intel processors?

I was sent a link to an article about the Intel compiler "crippling performance" on non-Intel processors. Any comments from the community on the veracity of the claim and whether or not the Fortran compiler is affected?

You're commenting about linux on a Windows forum, as well as asking for violation of the legal restrictions on free speech which you praise.
The comment about use of "the glibc" (meaning the oldest version you can find?) discriminating against certain brands of CPUs is as misleading as any. Major improvements in glibc have been instituted but not adopted by all major linux distros, even where agreement has been reached among advocates of various new and old CPU architectures.
If you're choosing this forum to advocate linux, at least agree that linux offers you a choice to update your run-time library.

Hey, I'm not advocating anything! I just got an e-mail about the "Intel compiler" and thought I would ask those more knowledgeable than I.

As I'm sure you'll understand, we Intel folks can't comment on this matter (other than the official legal spokespeople.)

Well, the article I saw about this indicated Intel agreed to fix it.
