Virtual Local Stores
Speakers:
Henry Cook
Abstract:

We propose a mechanism to provide the benefits of a software-managed memory hierarchy on top of a hierarchy of hardware-managed caches. A virtual local store (VLS) is mapped into the virtual address space of a process and backed by physical main memory, but is stored in a partition of the hardware-managed cache when active. This reduces context switch cost, and allows VLSs to migrate with their process thread. The partition allocated to the VLS can be rapidly reconfigured without flushing the cache, allowing programmers to selectively use VLS in a library routine with low overhead.
