Abstract: The present disclosure generally relates to the automated testing of a system that includes software or hardware components. In some embodiments, a testing framework generates a set of test cases for a system under test using a grammar. Each test case may perform an action, such as provide an input to the system under test, and result in an output from the system under test.

Specifically, the system under test may be analyzed to determine whether it is capable of properly processing control instructions and input signals and/or generating expected output control signals and additional control/feedback information. The data can then be interpreted in the grammar system and/or used as input to a fault isolation engine to determine anomalies in the system under test.

Abstract: This disclosure provides for host-controller cooperation in managing NAND flash memory. The controller maintains information for each erase unit which tracks memory usage. This information assists the host in making decisions about specific operations, for example, initiating garbage collection, space reclamation, wear leveling or other operations. For example, metadata can be provided to the host identifying whether each page of an erase unit has been released, and the host can specifically then command each of consolidation and erase using direct addressing. By redefining host-controller responsibilities in this manner, much of the overhead association with FTL functions can be substantially removed from the memory controller, with the host directly specifying physical addresses. This reduces performance unpredictability and overhead, thereby facilitating integration of solid state drives (SSDs) with other forms of storage.

The estimating unit estimates an idle period. When the idle state is detected, the determining unit determines whether a first power consumption when writeback of data which needs to be written back to a main storage device is performed and supply of power to a cache memory is stopped, is larger than a second power consumption when writeback of the data is not performed and supply of power is continued for the idle period.

Abstract: Embodiments of the invention relate to mitigating page eviction from cache memory. Pages of data in the cache are compressed, and are periodically swapped to a physical storage device to create space in the cache for additional pages. To avoid the impact of eviction latencies, an asynchronous thread scanning process scans the cache for any pages that are not committed to the storage device, decompresses a selected one of the pages, and asynchronously writes the decompressed page copy to the physical storage device. The compressed copy of the selected page remains in the cache during the asynchronous write with an indicator for the page set to convey that a replica of the page has been written to physical storage, allowing for efficient eviction from the in-memory pool at a later time.

Abstract: Webpages are optimizing through the use of experiments that compare the responses of viewers that are either presented with the original webpage or a variant thereof. One or more variants are first defined through the use of a browser-based editor application that initially examines the webpage for a snippet of code. The snippet can be added to the webpage, if missing, and the webpage returned to the editor application. Changes made to the webpage to define a variant are saved in variation code. When the webpage is later requested by multiple viewers, in each instance the viewer receives the webpage with the snippet, the snippet instructs the browser to download a file, and the instructions of the file determine whether the viewer will see the variant or the original webpage. Tracking viewer responses to the webpage and the variant allow a statistical basis for comparison to be developed.
