Selective multicast delivery on a bus-based interconnect

A computer program product for performing selective multicast delivery, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions executable by a selector of an intelligent processing unit (IPU) to cause the selector to perform a method comprising:

• identifying, by the selector, an address header appended to an instance of data, the address header including a single identifier comprising one or more bits;
• performing, by the selector, a lookup for the single identifier within one or more numeric identifiers stored at the selector;
• and
• conditionally delivering, by the selector, the instance of data, based on results of the lookup.
