Abstract: Methods and apparatus for an extended inter-kernel communication protocol for discovery of accelerator pools configured in a non-star mode. Under a discovery algorithm, discovery requests are sent from a root node to non-root nodes in the accelerator pool using an inter-kernel communication protocol comprising a data transmission protocol built over a Media Access Control (MAC) layer and transported over links coupled between IO ports on accelerators. The discovery requests are used to discover each of the nodes in the accelerator pool and determine the topology of the nodes. During this process, MAC address table entries are generated at the various nodes comprising (key, value) pairs of MAC IO port addresses identifying destination nodes and that may be reached by each node and the shortest path to reach such destination nodes. The discovery algorithm may also be used to discover storage related information for the accelerators. The accelerators may comprise FPGAs or other processing units, such as GPUs and Vector Processing Units (VPUs).
