摘要： A system and method for memory management. In one embodiment, the method includes generating a dependency structure comprising one or more task identifiers and one or more data object identifiers. The dependency structure includes a list of one or more dependencies for a first data object identifier of the one or more data object identifiers, a first dependency of the list identifying a first task for which a data object identified by the first data object identifier is an input. The method further includes counting the number of dependencies for the first data object identifier, decrementing the count by one when the first task completes execution, and, when the count reaches zero, deallocating the first data object.

摘要： A dual-server based storage system maintains a first cache and a first non-volatile storage (NVS) in a first server, and a second cache and a second NVS in a second server, where data in the first cache is also written in the second NVS and data in the second cache is also written in the first NVS. In response to a failure of the first server, a determination is made as to whether space exists in the second NVS to accommodate the data stored in the second cache. In response to determining that space exists in the second NVS to accommodate the data stored in the second cache, the data is transferred from the second cache to the second NVS.

摘要： A memory having a delayed write-back to the array of data corresponding to a previously opened page allows delays associated with write-back operations to be avoided. After an initial activation opens a first page and the read/write operations for that page are complete, write-back of the open page to the array of memory cells is delayed until after completion of a subsequent activate operation that opens a new page. Techniques to force a write-back in the absence of another activate operation are also disclosed.

摘要： In one example, uncompressed data is compressed and divided into chunks. Each chunk of the compressed data stream is combined with state information to enable each chunk to be independently decompressed. Each of the compressed chunks is then stored on a different storage device along with its associated state information. A compute operation can then be offloaded to the device or node where each chunk is stored. Each chunk can be independently decompressed for execution of the offloaded operation without transferring all chunks to a central location for decompression and performance of the operation.

摘要： Technologies for adaptive processing of multiple buffers is disclosed. A compute device may establish a buffer queue to which applications can submit buffers to be processed, such as by hashing the submitted buffers. The compute device monitors the buffer queue and determines an efficient way of processing the buffer queue based on the number of buffers present. The compute device may process the buffers serially with a single processor core of the compute device or may process the buffers in parallel with single-instruction, multiple data (SIMD) instructions. The compute device may determine which method to use based on a comparison of the throughput of serially processing the buffers as compared to parallel processing the buffers, which may depend on the number of buffers in the buffer queue.

摘要： A data backup method for backing up target data, through a driver module, from a first storage device to a second storage device is disclosed. The first storage device includes a first storage unit that stores the target data, and a first control unit that accesses the first storage unit based on a first logical-to-physical mapping table. The second storage device includes a second storage unit and a second control unit that accesses the second storage unit based on a second logical-to-physical mapping table. The method includes steps of: reading the target data from the first storage unit without accessing the first logical-to-physical mapping table and transmitting the target data to the driver module; transmitting the target data to the second control unit; and writing the target data to the second storage unit without accessing the second logical-to-physical mapping table.

摘要： Disclosed embodiments relate to one or more techniques to control access by a requestor of a computing system to a shared memory resource. In one embodiment, a technique includes determining a number (N) of pending requests to be sent to the memory by the requestor, determining a number (M) of requests that the requestor is limited to sending based on an amount of buffering resources available, and comparing M to N. When N is both greater than zero and less than or equal to M, the requestor sends the N pending requests to the memory. When N is both greater than zero and greater than M, M is compared to a hysteresis value (R) and, when M is less than R, the requestor sends R of the N pending requests to the memory.

摘要： A computer program product, according to one embodiment, includes a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to: receive, by the computer, a data set allocation request; determine, by the computer, whether a size of the data set is greater than a threshold; use, by the computer, first key values in a first index to select a volume in response to determining that the size of the data set is greater than the threshold; use, by the computer, second key values in a second index to select a volume in response to determining that the size of the data set is less than the threshold; perform, by the computer, the allocation request in the selected volume; and store, by the computer, control data about the data set in the control data set corresponding to the selected volume.
