As graphics processing units (GPUs) are broadly adopted, running multiple applications on a GPU at the same time is beginning to attract wide attention. Recent proposals on multitasking GPUs have focused on either spatial multitasking, which partitions ...

Cache is designed to exploit locality; however, the role of on-chip L1 data caches on modern GPUs is often awkward. The locality among global memory requests from different SMs (Streaming Multiprocessors) is predominantly harvested by the commonly-...
