Abstract: The present disclosure is directed to systems and methods sharing memory circuitry between processor memory circuitry and accelerator memory circuitry in each of a plurality of peer-to-peer connected accelerator units. Each of the accelerator units includes virtual-to-physical address translation circuitry and migration circuitry. The virtual-to-physical address translation circuitry in each accelerator unit includes pages for each of at least some of the plurality of accelerator units. The migration circuitry causes the transfer of data between the processor memory circuitry and the accelerator memory circuitry in each of the plurality of accelerator circuits. The migration circuitry migrates and evicts data to/from accelerator memory circuitry based on statistical information associated with accesses to at least one of: processor memory circuitry or accelerator memory circuitry in one or more peer accelerator circuits.
