Programmable multicast protocol for ring-topology based artificial intelligence systems

A system for providing enhanced multicast data transfer for ring topology based artificial intelligence systems in a computing environment, comprising:

• one or more computers with executable instructions that when executed cause the system to:
• send multicast data to a plurality of disjointed cores in a multicast group according to a first multicast mode, a second multicast mode, or a third multicast mode, wherein the first multicast mode sends a first half the multicast data on first multicast ring and a second half on a second multicast ring, the second multicast mode sends the multicast data on either the first multicast ring or the second multicast ring, and the third multicast mode replicates the multicast data and sends the multicast data to both the first multicast ring and the second multicast ring;
• and
• select between the first multicast mode or the second and third multicast mode, wherein a hardware logic is provided to select between the second multicast mode and the third multicast mode using a software instruction executed in the one or more processors, wherein, the logic utilizes an identifier of one or more requesting cores and distance to select between the second multicast mode and the third multicast mode.

A computer program product for providing enhanced multicast data transfer for ring topology based artificial intelligence systems in a computing environment, the computer program product comprising:

• one or more non-transitory computer readable storage media, and program instructions collectively stored on the one or more non-transitory computer readable storage media and executed by a processor, the program instruction comprising:
• program instructions to send multicast data to a plurality of disjointed cores in a multicast group according to a first multicast mode, a second multicast mode, or a third multicast mode, wherein the first multicast mode sends a first half the multicast data on first multicast ring and a second half on a second multicast ring, the second multicast mode sends the multicast data on either the first multicast ring or the second multicast ring, and the third multicast mode replicates the multicast data and sends the multicast data to both the first multicast ring and the second multicast ring;
• and
• program instructions to select between the first multicast mode or the second and third multicast mode, wherein a hardware logic is provided to select between the second multicast mode and the third multicast mode using a software instruction executed in the one or more processors, wherein, the logic utilizes an identifier of one or more requesting cores and distance to select between the second multicast mode and the third multicast mode.
