Hi Aaron and Alex,
I use the Intel compilers as part of Amber development and have never had
any compilation problems with any version of the compilers. Of course there
are several compiler bugs that can bite in places after compilation but we
have worked around most of these now. The Portland group compilers on the
other hand have always caused me more problems. One big issue was having to
force 32 bit compilation on x86_64 chips to work around a major problem in
the Portland group compiler. This of course causes problems linking to the
x86_64 optimized MKL libraries.
So my general advice is to get the latest Intel compiler and use this. This
generally appears to give the best performance on x86 / x86_64 architectures
including AMD Opterons.
What problems are you seeing with the Intel compilers?
All the best
Ross
