Build with PARDISO

Hi,

currently, I am trying o build NGSolve with PARDISO.

I have added the location of the downloaded library file from the Pardiso website to the LD_LIBRARY_PATH in my .bashrc file and have set the CMake flag DUSE_PARDISO=ON. However on "make" I get the Error "Could NOT find Pardiso".

What else do I have to do, in order for NGSolve to recognize Pardiso?

Best wishes,
Henry

Hi Henry,

There are two version of pardiso. The one from the pardiso homepage with a 3-month license or the pardiso that is shipped with the intel MKL. Typically we recommend using the MKL pardiso (the MKL itself isn't bad either). I am not sure if the other pardiso has been tested with ngsolve recently (Last time that I used it is approx. 9 years ago). My recommendation: Get Intel MKL (there are free versions for academic use), install it and set the ngsolve-cmake-options to point to the mkl-dependencies.

Best,

Hi Christoph,

unfortunately I have a machine with an AMD Ryzen 5 2400G processor running openSUSE Tumbleweed which is not supported by MKL. This is why I Tried to go via the pardiso homepage version.

Hi Henry,

What do you mean by "not supported"? Have you tried it or you are just missing your distro on the list of supported distros?

Hi Christoph,

the installer from the intel website gives me a warning, that my OS is not supported. I will try and install it anyway and see what happens.

Hi Christoph,

having ignored the pardiso installer warning, everything works fine now and NGSolve works with pardiso.

Thank you for your help!

Best wishes,
Henry
