The 1.3 libfabric release will contain the fi_trywait call. For providers, there are a couple of options available for handling this.
- The libfabric core can check that a provider supports the 1.3 API, and reject those that don't. This is the easy button. - The fi_trywait call can include a check against the provider's fabric ops to see if trywait was implemented. This conditional check would be in all fi_trywait paths. - The libfabric core can wrap the provider's fabric ops with its own copy of fabric ops. This requires mapping the provider's fabric fid to a core fabric fid for the sake of compatibility. This is only needed for providers asking for API < 1.3. This is the hard button. - Sean _______________________________________________ ofiwg mailing list [email protected] http://lists.openfabrics.org/mailman/listinfo/ofiwg
