Hi,
I want to use functions of LAPACK(Linear Algebra PACKage) in SU2 code. Please give some guidelines to do so. Thank you.

Hi,

Here below some instructions to use LAPACK and LAPACK with SU2. Please consider that such illlustration refers to the coupling we are carrying on internally at TU-Delft. In due course and after proper discussion with the rest of the developers LAPACK lib will be available in SU2 develop branch.

LAPACK-dir is the directory where the lapack lib is installed.


Installation of LAPACK:
1) Unzip lapack gz-file.
2) Copy the make.inc for the desired Fortran compiler from INSTALL to LAPACK-dir (in my case I copied make.inc.ifort [=Intel Fortran] and renamed it to make.inc).
3) Change in make.inc the line CC = icc to CC = gcc, if you need to use a different compiler than the one from Intel.
4) In Makefile, in the line starting with “lib:” add liblapacke.lib (and probably also blas.lib).
5) Compile LAPACK on your system by running make.


Enable in SU2:
1) Probably first: ./bootstrap
2) Then: ./configure --with-LAPACK-lib=LAPACK-dir/ --with-LAPACK-include=LAPACK-dir/lapacke/include/
3) Next the usual: make and make install
4) the header file to be used in your code in order to enable a lapack subroutine is lapacke.h

Best regards,
Matteo

Dear Matteo Pini,
Thank you for information. I will surely look into it.
