摘要： Methods of memory management are described which can accommodate non-maskable failures in pages of physical memory. In an embodiment, when an impending non-maskable failure in a page of memory is identified, a pristine page of physical memory is used to replace the page containing the impending failure and memory mappings are updated to remap virtual pages from the failed page to the pristine page. When a new page of virtual memory is then allocated by a process, the failed page may be reused if the process identifies that it can accommodate failures and the process is provided with location information for impending failures. In another embodiment, a process may expose information on failure-tolerant regions of virtual address space such that a physical page of memory containing failures only in failure-tolerant regions may be used to store the data instead of using a pristine page.

摘要： Provided are a system and program for managing operation requests using different resources. In one embodiment, a first queue is provided for operations which utilize a first resource of a first and second resource. A second queue is provided for operations which utilize the second resource. An operation is queued on the first queue until the first resource is acquired. The first resource is released if the second resource is not also acquired. The operation is queued on the second queue when the first resource is acquired but the second resource is not. In addition, the first resource is released until the operation acquires both the first resource and the second resource.

摘要： Various technologies and techniques are disclosed for providing software accessible metadata on a cache of a central processing unit. A multiprocessor has at least one central processing unit. The central processing unit has a cache with cache lines that are augmented by cache metadata. The cache metadata includes software-controlled metadata identifiers that allow multiple logical processors to share the cache metadata. The metadata identifiers and cache metadata can then be used to accelerate various operations. For example, parallel computations can be accelerated using cache metadata and metadata identifiers. As another example, nested computations can be accelerated using metadata identifiers and cache metadata. As yet another example, transactional memory applications that include parallelism within transactions or that include nested transactions can be also accelerated using cache metadata and metadata identifiers.

摘要： A stringed instrument tuning device is disclosed that is enhanced over the prior art by an included mechanism that enables the tuning knob to be positioned freely in any rotational position after a string has been tensioned or tuned. A worm gear drive tuning assembly typical of prior art tuning devices is employed. In one approach, the tuning device includes a common ratchet mechanism that enables free rotation of the tuning knob with respect to the tuning mechanism. In other embodiments disclosed, a spline shaft engagement mechanism is employed with a shuttle that releasably engages the tuning knob to the worm gear drive tuning assembly.

摘要： Various technologies and techniques are disclosed for providing software accessible metadata on a cache of a central processing unit. The metadata can include at least some bits for each virtual address, at least some bits for each cache line, and at least some bits for the cache overall. An instruction set architecture on the central processing unit is provided that includes additional instructions for interacting with the metadata. New side effects that are introduced into an operation of the central processing unit by a presence of the metadata and the additional instructions. The metadata can be accessed by at least one software program to facilitate an operation of the software program.
