[mpas-developers] Block Decomposition Revision

[Doug Jacobsen]

Hi All,

Continuing with the work that Michale previously proposed before the
derived data type revision, I am starting work on revisions to the block
decomposition module to support multiple blocks per mpi process. As a
refresher, this item was previously described as

4) Modify the block_decomp module to enable a task to get a list of
    cells in more than one block that it is to be the owner of.
    Implemented in the simplest way, there could simply be a namelist
    option to specify how many blocks each task should own, and the
    block_decomp module could look for a graph.info.part.n file, with
    n=num_blocks_per_task*num_tasks, and assign blocks k, 2k, 3k, ...,
    num_blocks_per_task*k to task k.

I have attached a design document (pdf and latex) related to this task.
Please let me know if you have any comments or suggestions. I would like to
have this implemented by the end of the week. Thanks for any feedback.

Doug
