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.

Abstract: Various technologies and techniques are disclosed for providing a bounded transactional memory application that accesses cache metadata in a cache of a central processing unit. When performing a transactional read from the bounded transactional memory application, a cache line metadata transaction-read bit is set. When performing a transactional write from the bounded transactional memory application, a cache line metadata transaction-write bit is set and a conditional store is performed. At commit time, if any lines marked with the transaction-read bit or the transaction-write bit were evicted or invalidated, all speculatively written lines are discarded. The application can also interrogate a cache line metadata eviction summary to determine whether a transaction is doomed and then take an appropriate action.

Abstract: A memory management system is described herein that receives information from applications describing how memory is being used and that allows an application host to exert more control over application requests for using memory. The system provides an application memory management application-programming interface (API) that allows the application to specify more information about memory allocations that is helpful for managing memory later. The system also provides an ability to statically and/or dynamically analyze legacy applications to give applications that are not modified to work with the system some ability to participate in more effective memory management. The system provides application host changes to leverage information provided by applications and to manage memory more effectively using information and hooks into application's use of memory. Thus, the system provides a new model for managing memory that improves application host behavior and allows applications to use computing resources more efficiently.

Abstract: 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.

Abstract: Various technologies and techniques are disclosed for providing a hardware accelerated software transactional memory application. The software transactional memory application has access to metadata in a cache of a central processing unit that can be used to improve the operation of the STM system. For example, open read barrier filtering is provided that uses an opened-for-read bit that is contained in the metadata to avoid redundant open read processing. Similarly, redundant read log validation can be avoided using the metadata. For example, upon entering commit processing for a particular transaction, a get-evictions instruction in an instruction set architecture of the central processing unit is invoked. A retry operation can be optimized using the metadata. The particular transaction is aborted at a current point and put to sleep. The corresponding cache line metadata in the metadata are marked appropriately to efficiently detect a write by another CPU.
