This PR introduces the ability to register the component only to the select functions specified by an MCA parameter string. The idea and the code is based on the UCC component, and some of the bits might be moved later to coll/base to make the mechanism more gnerally available to other components as well. Note, that the PR introduces the define statments for all MPI collective operations, not just the ones support by the component at the moment, since it is a bitmask based operation, and we anticipate to add support for more collective operations into coll/accelerator shortly Signed-off-by: Edgar Gabriel <[email protected]>
