    摘要： Instructions and logic provide memory fence and store functionality. Some embodiments include a processor having a cache to store cache coherent data in cache lines for one or more memory addresses of a primary storage. A decode stage of the processor decodes an instruction specifying a source data operand, one or more memory addresses as destination operands, and a memory fence type. Responsive to the decoded instruction, one or more execution units may enforce the memory fence type, then store data from the source data operand to the one or more memory addresses, and ensure that the stored data has been committed to primary storage. For some embodiments, the primary storage may comprise persistent memory. For some embodiments, cache lines corresponding to the memory addresses may be flushed, or marked for persistent write back to primary storage. Alternatively the cache may be bypassed, e.g. by performing a streaming vector store.

    摘要： Various embodiments are generally directed to techniques for compiler sheltered nonvolatile memory (NVM) stores, such as based on demarcated atomic persistence regions in source code, for instance. Some embodiments are particularly related to a compiler that effectively shelters updates to NVM-based variables in a compiler implemented register, or register file, until the compiler has recorded undo values into a temporary but nonvolatile log range.

    摘要： Embodiments may include systems and methods for performing remote memory operations in a shared memory address space. An apparatus includes a first network controller coupled to a first processor core. The first network controller processes a remote memory operation request, which is generated by a first memory coherency agent based on a first memory operation for an application operating on the first processor core. The remote memory operation request is associated with a remote memory address that is local to a second processor core coupled to the first processor core. The first network controller forwards the remote memory operation request to a second network controller coupled to the second processor core. The second processor core and the second network controller are to carry out a second memory operation to extend the first memory operation as a remote memory operation. Other embodiments may be described and/or claimed.

    摘要： Embodiments may be directed to techniques to execute a binary based on source code comprising basic blocks of instructions, identify a path of execution of a plurality of the basic blocks of instructions having a higher execution frequency than an execution frequency threshold, and collect last branch records for the plurality of the basic blocks of instructions, the last branch records to indicate times of execution for the plurality of the basic blocks of instructions. Further, embodiments include determining latency values for each of the plurality of the basic blocks of instructions based on the times of execution, and performing a mitigation operation for each of the plurality of the basic blocks of instruction having latency values above a latency threshold.

    摘要： Methods, apparatus, systems and articles of manufacture (e.g., physical storage media) for software defined silicon guardianship are disclosed. An example method for semiconductor feature guardianship includes identifying, with a co-processor of a first semiconductor device, a feature based on a license received via a network from a remote enterprise system, the feature activated on a first semiconductor device based on the license, generating, with the co-processor of the first semiconductor device, a mesh network, the mesh network including a plurality of nodes associated with respective semiconductor devices including the first semiconductor device, the plurality of nodes including a primary node in communication with one or more secondary nodes, and migrating, with the co-processor of the first semiconductor device, the feature from a first secondary node to a second secondary node in response to a feature failure even on the first secondary node, the migration to maintain a feature entitlement associated with the license.

    摘要： Two identity spaces form a federation by agreeing to use a secret key to facilitate secure access of resources between them. When one identity space receives a request for a resource from a user in the other identity space, the first identity space checks to see if the resource is protected. If the resource is protected, the first identity space requests that a mediator in the second identity space authenticate the external user. The mediator verifies the external user's authenticity. Once the external user is authenticated, the mediator securely informs the first identity space, using the secret key, that the external user is authenticated to access the resource. The identity space then grants the user access to the resource if the user is allowed access as per the access control policy of the identity space.
