Abstract: Techniques for remote disaggregated infrastructure processing units (IPUs) are described. An apparatus described herein includes an interconnect controller to receive a transaction layer packet (TLP) from a host compute node; identify a sender and a destination from the TLP; and provide, to a content addressable memory (CAM), a key determined from the sender and the destination. The apparatus as described herein can further include core circuitry communicably coupled to the interconnect controller, the core circuitry to determine an output of the CAM based on the key, the output comprising a network address of an infrastructure processing unit (IPU) assigned to the host compute node, wherein the IPU is disaggregated from the host compute node over a network; and send the TLP to the IPU using a transport protocol.
