Intel compilers

Om de Intel compilers te gebruiken moeten er een aantal omgevingsvariabelen gezet zijn, voor csh gebruikers kan dit eenvoudig door het commando:

source /opt/intel/bin/ifortvars.csh intel64

op te nemen in .cshrc

voor mensen met bash, voeg de volgende regel

source /opt/intel/bin/ifortvars.sh intel64

toe aan .bash_rc

How to create a standalone MKL version of BLAS and LAPACK shared libraries ?

This is described in detail in Building Custom Shared Objects

• Create a new directory (e.g. ~/lib)

 mkdir ~/lib
 cd ~/lib

• Copy these files:

 cp /opt/intel/composerxe/mkl/tools/builder/{makefile,blas_list,lapack_list} ~/lib

• Set the MKLROOT variable (in bash):

 MKLROOT=/opt/intel/mkl
 export MKLROOT

In tcsh use:

 setenv MKLROOT /opt/intel/mkl

• Make the shared libraries libblas_mkl.so and liblapack_mkl.so

 make libintel64 export=blas_list interface=lp64  threading=parallel name=libblas_mkl
 make libintel64 export=lapack_list interface=lp64  threading=parallel name=liblapack_mkl

The options are described here

The newly created libblas_mkl.so and liblapack_mkl.so require

 /opt/intel/lib/intel64/libiomp5.so
 

to work. On the cluster nodes this file is automatically linked when required.
