[MLUG] gcc and Intel compilers for Linux

[Mike Miller <EMAIL:PROTECTED>]

Have you guys checked out the Intel compilers?  One of our MSI 
(supercomputer) geeks told me that they find "up to" a 4-fold speed 
improvement using the Intel compiler instead of gcc.  Smaller improvements 
(e.g., 20%) are more common, of course, but he thought Intel's compiler 
nearly always produced a faster binary than did gcc.  The newest versions 
of the free intel compilers are highly gcc compatible, he told me.  They 
are freely available for noncommercial use (but obviously not free 
software).

Here they use the term "Free Software" in a deceptive way:

I thought this was kinda interesting:

Q. I'm developing a product that I provide for free. However, I do charge 
for supporting this product. Can I use the noncommercial products for 
developing this product?

A. No. Even though the product you develop is free, it is part of an 
overall commercial offering.


Crazy.  Anyway, the commercial version won't bankrupt anyone.


What are your opinions of this Intel initiative?

Mike
