[Wien] Which compiler and lirary recommend for AMD Athion 64

[Torsten Andersen]

Use the AMD library (ACML 2.0) with some compiler (e.g., PGI, or, maybe 
even the iNtel compiler). Remember to check the results, as some 
compiler options may give problems. With the PGI compiler, for example, 
-O5 works with the testcase, but not with any other of my 
calculations... Compilers are in general buggy, and not many of them 
will allow a universal set of compiler flags for all programmes to be 
compiled so that they work flawlessly (especially the "properties" 
programmes, usually the programmes required in the SCF cycle are easy to 
compile and optimize). Remember to add the compiler options also on the 
linker level, if the linker is able to do optimizations.

Best regards,
Torsten Andersen.
