Multi-chip electro-photonic network

A system comprising:

• a first circuit package comprising:
• an electronic integrated circuit (EIC) comprising a plurality of first processing elements and a plurality of first message routers;
• and
• a plurality of first intra-chip bidirectional photonic channels, wherein each first intra-chip bidirectional photonic channel directly connects exactly two message routers of the plurality of first message routers;
• a second circuit package comprising:
• a second EIC comprising a plurality of second processing elements and a plurality of second message routers;
• and
• a plurality of second intra-chip bidirectional photonic channels, wherein each second intra-chip bidirectional photonic channel directly connects exactly two message routers of the plurality of second message routers;
• and
• a plurality of inter-chip bidirectional photonic channels, wherein each inter-chip bidirectional photonic channel directly connects one of the plurality of first message routers to a respective one of the plurality of second message routers;
• wherein, for each message router of the plurality of first message routers and of the plurality of second message routers:
• the message router is connected to more than one other message routers;
• and
• the message router is configured to:
• receive a message originating from an originating processing element;
• select a message router from among the more than one other message routers to transmit the message to, the selected message router being on a transmission path from the originating processing element to a destination processing element identified in the message;
• and
• transmit the message to the selected message router over a photonic channel connecting the message router to the selected message router, the photonic channel being one photonic channel of the pluralities of first intra-chip bidirectional photonic channels, second intra-chip bidirectional photonic channels, or inter-chip bidirectional photonic channels.
