Abstract
An approach is provided for managing near-memory processing commands ('PIM commands') from multiple processor threads in a manner to prevent interference and maintain correctness at near-memory processing elements. A memory controller uses thread identification information and last command information to issue a PIM command sequence from a first processor thread, directed to a PIM-enabled memory element, while deferring the issuance of PIM command sequences from other processor threads, directed to the same PIM-enabled memory element. After the last PIM command in the PIM command sequence for the first processor thread has been issued, a PIM command sequence for another processor thread is issued, and so on. The approach allows multiple processor threads to concurrently issue fine grained PIM commands to the same PIM-enabled memory element without having to be aware of address-to-memory element mapping, and without having to coordinate with other threads.
