Abstract: An Address Mapping-Aware Tasking (AMAT) mechanism manages compute task data and issues compute tasks on behalf of threads that created the compute task data. The AMAT mechanism stores compute task data generated by host threads in a set of partitions, where each partition is designated for a particular memory module. The AMAT mechanism maintains address mapping data that maps address information to partitions. Threads push compute task data to the AMAT mechanism instead of generating and issuing their own compute tasks. The AMAT mechanism uses address information included in the compute task data and the address mapping data to determine partitions in which to store the compute task data. The AMAT mechanism then issues compute tasks to be executed near the corresponding memory modules (i.e., in PIM execution units or NUMA compute nodes) based upon the compute task data stored in the partitions.
