摘要： Fine-grained enablement at sub-function granularity. An instruction encapsulates different sub-functions of a function, in which the sub-functions use different sets of registers of a composite register file, and therefore, different sets of functional units. At least one operand of the instruction specifies which set of registers, and therefore, which set of functional units, is to be used in performing the sub-function. The instruction can perform various functions (e.g., move, load, etc.) and a sub-function of the function specifies the type of function (e.g., move-floating point; move-vector; etc.).

摘要： A computer implemented method and system for delaying a floating interruption while a processor is in a transactional-execution mode. A floating interruption mechanism can detect a floating interruption request for one or more floating interruption eligible processors. Based on each eligible processor being in TX mode, the method and system can delay, using a predetermined period of time, performing the floating interruption at a selected processor of the one or more of the processors. A first processor of the one or more processors can be selected based on the first processor exiting the transactional execution mode within the predetermined period of time. Based on the predetermined period of time expiring, the method and system can cause an interrupt to one of the plurality of processors, and the interrupt can cause the processor to abort a transaction.

摘要： Configuration state registers grouped based on functional affinity. An identification of an in-memory configuration state register for which memory is assigned is obtained. Based on the identification, an offset into the memory at which the in-memory configuration state register is stored is determined. The offset is allocated to the in-memory configuration state register based on functional affinity of the in-memory configuration state register. The in- memory configuration state register is accessed using at least the offset.

摘要： A memory management service occupies a configurable portion of an overall memory system in a disaggregate compute environment. The service provides optimized data organization capabilities over the pool of real memory accessible to the system. The service enables various types of data stores to be implemented in hardware, including at a data structure level. Storage capacity conservation is enabled through the creation and management of high-performance, reusable data structure implementations across the memory pool, and then using analytics (e.g., multi-tenant similarity and duplicate detection) to determine when data organizations should be used. The service also may re-align memory to different data structures that may be more efficient given data usage and distribution patterns. The service also advantageously manages automated backups efficiently.

摘要： Context switch by changing memory pointers. A determination is made that a context switch is to be performed from a first context to a second context. Data of the first context is stored in one or more configuration state registers stored at least in part in a first memory unit and data of the second context is stored in one or more configuration state registers stored at least in part in a second memory unit. The context switch is performed by changing a pointer from the first memory unit to the second memory unit.
