摘要： Embodiments of the present invention provide a flash memory device write-access management amongst different virtual machines (VMs) in a virtualized computing environment. In one embodiment, a virtualized computing data processing system can include a host computer with at least one processor and memory and different VMs executing in the host computer. The system also can include a flash memory device coupled to the host computer and accessible by the VMs. Finally, a flash memory controller can manage access to the flash memory device. The controller can include program code enabled to compute a contemporaneous bandwidth of requests for write operations for the flash memory device, to allocate a corresponding number of tokens to the VMs, to accept write requests to the flash memory device from the VMs only when accompanied by a token and to repeat the computing, allocating and accepting after a lapse of a pre-determined time period.

摘要： A processing system is disclosed. The processing system includes a memory and a first core configured to process applications. The first core includes a first cache. The processing system includes a mechanism configured to capture a sequence of addresses of the application that miss the first cache in the first core and to place the sequence of addresses in a storage array; and a second core configured to process at least one software algorithm. The at least one software algorithm utilizes the sequence of addresses from the storage array to generate a sequence of prefetch addresses. The second core issues prefetch requests for the sequence of the prefetch addresses to the memory to obtain prefetched data and the prefetched data is provided to the first core if requested.
