Intel Fortran 2015 and MKL95_LAPACK

[Towie__Ewan]

Hi there,

I recently updated to the 2015 Fortran compiler and I am currently trying to get my source code to compile with the new version. So far I had a catastrophic compiler error which I have managed to resolve, but I am really stuck now!

The previous version of Intel Fortran, 2013 SP1, still had the MKL95_LAPACK module available in <install dir>/intel/composer_xe_2013_sp1.5.212/mkl/include/intel64/lp64/ but the new 2015 release this module is now not available.

As I am using the specific F95 Lapack functions, what can I do now?

Thanks :)

There is definitely a selection for blas95/lapack95 in recent installers.  I think it was off by default in some versions.

Did you skip an installation option for blas95/lapack95 under MKL?

The old module would probably still work.

Not that I am aware of. I don't recall there being any options with the install at all?

I will try copying the file over to the new install, but it's not really a great solution.

Inside the .../mkl/include directory you have, in addition to others, the files blas.f90 and lapack.f90. Compiling those two files with the current compiler will produce the module files that you seek. After producing the module files, you may place them into the mkl/include/ia32 and mkl/include/intel64 subdirectories, as appropriate.

Just to close this issue, and for future reference for anyone else having the same problem..

I managed to resolve this problem which appeared to be that the F95 LAPACK module name changed between the 2013 SP1 (and previous) and 2015 compiler releases. There is actually support for both the new and old named modules in 2013 SP1, and in 2015 the old named module appears to have been deprecated.

So, my USE statement in Fortran went from

USE mkl95_PRECISION, ONLY: WP => DP
USE mkl95_LAPACK, ONLY: SBEV,GEEV

to

USE f95_precision, ONLY: WP => DP
USE lapack95, ONLY: SBEV,GEEV

I wasn't able to find any documentation to state why this happened, or if anything has changed internally (not to say that there isn't any documentation!).
