Need of MPI_Sendrecv_replace interfaces
andreapiacentini opened this issue · comments
We (Benjamin Ménétrier and myself) are trying to optimize a 4D localization in JEDI-OOPS, based on an open-end shift. We miss an eckit interface to MPI_Sendrecv_replace. In order to implement open-end shifts, we also need a method to expose the MPI_PROC_NULL
constant.
Thank you.
This has been solved with #57
