[petsc-dev] configure issues with new MKL and --with-mkl_sparse_optimize=0

[Mills, Richard Tran]

Hi Stefano,

Apologies for the slow reply; I was out for the US Thanksgiving Holiday.

You've found an error in the logic for the MKL configure tests: Your MKL does indeed have mkl_sparse_sp2m(), but since this depends on having mkl_sparse_optimize() and you have specified '--with-mkl_sparse_optimize=0', PETSC_HAVE_MKL_SPARSE_SP2M either ought to not be defined, or in my AIJMKL code I should only enable the SP2M code if PETSC_HAVE_MKL_SPARSE_OPTIMIZE is defined. I think I like the former option better. For those more familiar with BuildSystem than I am, I think I can do this by putting the following in setupDependencies() in mkl_sparse_sp2m.py:

    self.mkl_sparse_optimize  = framework.require('config.packages.mkl_sparse_optimize', self)
    self.deps                           = [self.blasLapack,self.mkl_sparse_optimize]

Is that all that is required?

Richard,

I just noticed that PETSc master does not build with the options

    '--with-mkl_pardiso-dir=/soft/com/packages/intel/18/u3/mkl',
    '--with-mkl_sparse_optimize=0',

This is on frog at MCS, but it will be the same on other machines as the macros configuration

PETSC_HAVE_MKL_SPARSE_OPTIMIZE not defined
PETSC_HAVE_MKL_SPARSE_SP2M defined

does not seem to be supported.

/nfs2/szampini/src/petsc/src/mat/impls/aij/seq/aijmkl/aijmkl.c(797): error: struct "<unnamed>" has no field "csrA"
    csrA = a->csrA;

Could you please take a look? Why is the mkl_sparse_sp2m package flagged as lookforbydefault in the configure scripts?

Thanks
