Abstract: In various examples, when a bridge of a chip has received an eviction request from a client of the chip, the bridge may transmit a read request that corresponds to the same cache line to another chip without waiting for an inter-chip completion response for the eviction request. When the read request is received, the bridge may determine whether the eviction request has already been sent to the other chip and transmit the read request based at least on the eviction request being sent to the other chip using an ordered communication network to ensure the communications are received and/or processed by the other chip in an order that maintains memory coherency. Additionally, the chips may process read unique requests without using an inter-chip completion acknowledgement and may process copy back requests by transmitting corresponding copy back write data with the copy back requests.
