Python Interface to BLACS and ScaLAPACK Mostly non-Python related challenges: Good ScaLAPACK examples are few and far apart. DFT leads to wieldy use of ScaLAPACK H_mn is on a small subset of MPI_COMM_WORLD ScaLAPACK does not create a distribute object for you. Array must be created in a distributed manner ScaLAPACK allows you to manipulate them via descriptors Array must be compatible with their native 2D-block cyclic layout What language was used to write ScaLAPACK and BLACS? C and Fortran Distributed arrays assumed to be Fortran-ordered.
