[Pw_forum] AMD Core Math Library & PWSCF

[Konstantin Kudin]

 Hi there,

 I thought I'd share how to link PWSCF with the AMD
Core Math Library (ACML). It is free and supposed to
be well optimized.

(http://www.amd.com/us-en/Processors/DevelopWithAMD/0,,30_2252_2282,00.html)
 
 For ifc 8.0 replace MKL libraries with:

/usr/acml1.5/gnu32_nosse2/lib/libacml.so
/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/libg2c.so
(or use .a instead of .so)
Libg2c is needed to make libacml happy.

 In pgf 5.1 this library is included with the
compiler.
To use that, add options:

-lacml -lpgmp -lpgthread

 If you want to use the one from the AMD website, use:

/usr/acml1.5/pgi32_nosse2/lib/libacml.so

 Good luck.

 Kostya
