Hi, I found that when compiled with '--with-64-bit-indices=1' option, the following three definitions in petscconf.h will be removed:
#define PETSC_HAVE_MKL_SPARSE 1 #define PETSC_HAVE_MKL_SPARSE_OPTIMIZE 1 #define PETSC_HAVE_MKL_SPARSE_SP2M_FEATURE 1 I believe mkl can also use 64-bit indices (libmkl_intel_ilp64). I tried to add ' --with-mkl_sparse=1 --with-mkl_sparse_optimize=1' into configuration but does not succeed. Would I know if it is possible to use MATSEQAIJMKL matrix type in 64-bit mode? Regards, Di
