Patent ID: 11343083

Abstract:
A host processing device instructs a plurality of virtual data processing (VDP) accelerators, configured on each of a plurality of data processing accelerators. The VDP accelerators configure themselves for secure communications. The host device generates an adjacency table of each of the plurality of VDP accelerators. Then the host device then establishes a session key communication with each VDP accelerator and sends the VDP accelerator a list of other VDP accelerators that the VDP accelerator is to establish a session key with, for secure communications between the VDP accelerators. The VDP accelerator establishes a different session key for each pair of the plurality of VDP accelerators. When all DP accelerators have established a session key for communication with other VDP accelerators, according to the respective list of other VDP accelerators sent by the host device, then the host device can assign work tasks for performance by a plurality of VDP accelerators, each communicating over a separately secured virtual communication channel.
