Someone else recommended the Intel Compilers, I just mentioned that
there are restrictions on what Intel considers "academic use".
However, since you asked, commercial compilers generally optimize the
code better than GCC. The performance/cost trade-off needs be be
determined by you. If you do have a limited budget, GCC will probably be
Regardless of your compiler, you should look at optimized libraries to
boost your performance. GotoBLAS, for example, is hand-optimized and is
very fast for linear algebra operations. Because it's hand optimized
with assembly code (or so I've been told) - never used it myself), it's
performance should be the same regardless of the compiler.
