public subroutine dbcsr_tas_benchmark_mm(transa, transb, transc, matrix_a, matrix_b, matrix_c, compare_dbcsr, filter_eps, io_unit)

type(dbcsr_tas_type), intent(inout) :: matrix_c
logical, intent(in) :: compare_dbcsr
real(kind=real_8), intent(in), optional :: filter_eps
integer, intent(in), optional :: io_unit

public subroutine dbcsr_tas_test_mm(transa, transb, transc, matrix_a, matrix_b, matrix_c, filter_eps, unit_nr, log_verbose)

Test tall-and-skinny matrix multiplication for accuracy
