Hi Howard and all Thank you very much for the information. I have a follow up question:
If the vendor of a new type of fabric wants to include support for OpenMPI, then, as long as they can implement a libfabric provider, they can use the OFI MTL without adding any code to the OpenMPI source tree itself. Is the above statement correct? Note that I am trying to contrast against the other possibility, implementing a BTL, that does not add anything to the libfabrics source tree but adds to OpenMPI source tree instead. Thanks Durga We learn from history that we never learn from history.
