Hi again, so I haven't complete the mkl-cpardiso interface for some compilation problems. However I did an interfaces for the regular pardiso that comes with intel-mkl. Now there are a couple of things pending to do before to do the pool request:
1. I did a mkl-pardiso.py script for the installation of the solver. It checks that BlasLapack is installed, but it doesn't check that the BlasLapack implementation is mkl implementation. I did't know how to do that so maybe you cold helpme with that. 2. Intel suggest to use the following flags for the linker phase "-Wl,--start-group -L(PATH_TO_MKL) -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -Wl,--end-group -lpthread -lm -liomp5". This is simple if I use -with-mkl-pardiso-lib. But if I want to use -with-mkl-pardiso-dir is more complicated and need to be done. 3. Finally related with the -with-mkl-pardiso-dir I don't if would be necessary to do a library validation, apart from the BlasLapack validation. If you could help me with this question, I would be able to do a pull request soon.

Well the easier configuration is not a high priority think for me(but it something that in some point I will have to do). So for now I will have a basic cpardiso.py and then I will try to ensure that the blas/lapack libraries are correct. ----- Original Message ----- From: "Barry Smith" <[email protected]> To: "Jose David Bermeol" <[email protected]> Cc: "petsc-users" <[email protected]>, "For users of the development version of PETSc" <[email protected]> Sent: Sunday, October 6, 2013 10:54:53 PM Subject: Re: [petsc-dev] [petsc-users] mkl-cpardiso configuration Jose, Since you are currently working on interfacing cpardiso I would just have a cpardiso.py (or cpardiso_mkl.py) (and NO mkl.py) that manages/lists the libraries needed for cpardiso. Don't have both a cpardiso.py and cpardiso_mkl.py. Since, as Satish reports, cpardiso.py brings in also the mkl blas/lapack I would also have the cpardiso.py script check that the blas/lapack libraries being linked are compatible with the cpardiso mkl libraries being brought in and provide a useful error message telling them how to set the blas/lapack libraries to fix the problem when needed. We definitely do not want to muddy up the already horrible blaslapack.py code by introducing the concept of cpardiso there. Anyways, once you've simplified things, just make a pull request at bitbucket and we can try it and help with the kinks.
