added new fc_lapack test

miroi commented 9 years ago

checked with GNU/Intel/PGI compilers and the MKL library
- also fixed tests fc, fc_blas for PGI compiler

Wished to have core autocmake-blas/lapack tests running with many compilers as prelude for developing autocmake-DIRAC/

bast commented 9 years ago

I don't think we need random numbers. This will simplify the module and avoid the compiler ifdefs.
The LAPACK test should test LAPACK and not also BLAS (we have a BLAS test). Test one thing and one thing only. The reason is that now if LAPACK test fails you don't know whether for BLAS or LAPACK reasons.
Flags --blas=auto --lapack=auto are not needed since it is default.

Fine, I am going to simplify the test. So I have to supply data manually for A,b and check roots manually also.

bast commented 9 years ago

How about just diagonalizing a 2x2 matrix. Then it is easy to provide everything manually. No random stuff needed then.

Hi,

I have solving linear equations from lapack (DGESV). Will find some 3x3 system.

miroi commented 9 years ago

Pffffffuh, all two tests are green. Nice :+1:

miroi commented 9 years ago

Hi, are there any reasons against this PR ? I would be glad to have it in master, to experiment with lapack static linking....

bast commented 9 years ago

Thanks Miro. Two more questions from my side: What CMake version are you using on the machine with PGI and is the -rdynamic hack needed also with the latest CMake version?

miroi commented 9 years ago

Hi, i) CMake version:

milias@login.grid.umb.sk:~/Work/qch/software/software_projects/autocmake_devel/autocmake_miroi/.cmake --version
cmake version 2.8.12.2

ii) Ad -rdynamic hack : this I don't know. The CMake adds a lot of stuff into linking command, and sometimes we have to purify it of offensive flags. I don't know how this is developing with CMake versions, simply we have to watch it.

bast commented 9 years ago

Can you please try it with latest CMake? Because perhaps we are trying to workaround a problem that has been solved.

miroi commented 9 years ago

Hi,

the latest CMake also includes offensive flag for pgf90:

milias@login.grid.umb.sk:~/Work/qch/software/software_projects/autocmake_devel/autocmake_miroi/test/fc_blas/.python setup.py --fc=pgf90 
FC=pgf90 cmake -DEXTRA_FCFLAGS="''" -DENABLE_STATIC_LINKING=False -DENABLE_64BIT_INTEGERS=False -DENABLE_BLAS=auto -DENABLE_LAPACK=auto -DMKL_FLAG=off -DMATH_LIB_SEARCH_ORDER="MKL;ESSL;ATLAS;ACML;SYSTEM_NATIVE" -DBLAS_LANG=Fortran -DLAPACK_LANG=Fortran -DEXPLICIT_LIBS=off -DCMAKE_BUILD_TYPE=release -G "Unix Makefiles" None /home/milias/Work/qch/software/software_projects/autocmake_devel/autocmake_miroi/test/fc_blas

OK thanks for testing it. Then we probably need to have it in the test script.

added new fc_lapack test #50
