Abstract: An embodiment of a system for determining the disposition of a hyperdocument and hyperdocument requests using a trained artificial neural network, including an information source, a requesting application, and a server containing a trained artificial neural network (ANN), the ANN being capable of evaluating the information, and providing results reflecting the evaluation to a requesting application is described.

Abstract: A log structure is created in persistent memory using hardware support in memory controller or software supported with additional instructions. Writes to persistent memory locations are streamed to the log and written to their corresponding memory location in cache hierarchy. An added victim cache for persistent memory addresses catches cache evictions, which would corrupt open transactions. On the completion of a group of atomic persistent memory operations, the log is closed and the persistent values in the cache can be copied to their source persistent memory location and the log cleaned.

Abstract: Emerging byte-addressable persistent memory technologies, generically referred to as Storage Class Memory, offer performance advantages and access similar to Dynamic Random Access Memory while having the persistence of disk. Unifying storage and memory into a memory tier that can be accessed directly requires additional burden to ensure that groups of memory operations to persistent or nonvolatile memory locations are performed sequentially, atomically, and not caught in the cache hierarchy. The present invention provides a lightweight solution for the atomicity and durability of write operations to nonvolatile memory, while simultaneously supporting fast paths through the cache hierarchy to memory. The invention includes a hardware-supported solution with modifications to the memory hierarchy comprising a victim cache and additional memory controller logic.

Abstract: Persistent Memory, byte-addressable non-volatile memory technologies, offer performance advantages and access similar to Dynamic Random Access Memory while having the persistence of disk. Hardware Transactional Memory support, originally designed for DRAM concurrency control, can corrupt persistent memory transactions due to cache evictions before system failure. Unifying storage and memory on the main-memory bus and accessed directly while using HTM for concurrency control has previously required the additional burden of changes to processors to prevent possible data corruption. The present invention provides a solution for the durability of transactions to persistent memory while using HTM as a concurrency control mechanism, without any changes to processors or cache-coherency mechanisms. The invention includes a software only method and system that provides durability and ordering of HTM transactions to persistent memory.

Abstract: An embodiment of a computer implemented method for determining the disposition of a hyperdocument includes retrieving a hyperdocument from an information source, providing information about content of the hyperdocument to a trained artificial neural network (ANN), the ANN being capable of evaluating the information and providing results reflecting the evaluation, and determining the disposition of the hyperdocument based upon results of the ANN.
