Abstract: A central processing unit can offload table lookup or tree traversal to an offload engine. The offload engine can provide hardware accelerated operations such as instruction queueing, bit masking, hashing functions, data comparisons, a results queue, and a progress tracking. The offload engine can be associated with a last level cache. In the case of a hash table lookup, the offload engine can apply a hashing function to a key to generate a signature, apply a comparator to compare signatures against the generated signature, retrieve a key associated with the signature, and apply the comparator to compare the key against the retrieved key. Accordingly, a data pointer associated with the key can be provided in the result queue. Acceleration of operations in tree traversal and tuple search can also occur.

Abstract: Embodiments of systems, apparatuses and methods provide enhanced function as a service (FaaS) to users, e.g., computer developers and cloud service providers (CSPs). A computing system configured to provide such enhanced FaaS service include one or more controls architectural subsystems, software and orchestration subsystems, network and storage subsystems, and security subsystems. The computing system executes functions in response to events triggered by the users in an execution environment provided by the architectural subsystems, which represent an abstraction of execution management and shield the users from the burden of managing the execution. The software and orchestration subsystems allocate computing resources for the function execution by intelligently spinning up and down containers for function code with decreased instantiation latency and increased execution scalability while maintaining secured execution. Furthermore, the computing system enables customers to pay only when their code gets executed with a granular billing down to millisecond increments.

Abstract: Apparatus, method, and system for implementing a software-transparent hardware predictor for core-to-core data communication optimization are described herein. An embodiment of the apparatus includes a plurality of hardware processor cores each including a private cache; a shared cache that is communicatively coupled to and shared by the plurality of hardware processor cores; and a predictor circuit. The predictor circuit is to track activities relating to a plurality of monitored cache lines in the private cache of a producer hardware processor core (producer core) and to enable a cache line push operation upon determining a target hardware processor core (target core) based on the tracked activities. An execution of the cache line push operation is to cause a plurality of unmonitored cache lines in the private cache of the producer core to be moved to the private cache of the target core.

Abstract: Technology for a memory pool arbitration apparatus is described. The apparatus can include a memory pool controller (MPC) communicatively coupled between a shared memory pool of disaggregated memory devices and a plurality of compute resources. The MPC can receive a plurality of data requests from the plurality of compute resources. The MPC can assign each compute resource to one of a set of compute resource priorities. The MPC can send memory access commands to the shared memory pool to perform each data request prioritized according to the set of compute resource priorities. The apparatus can include a priority arbitration unit (PAU) communicatively coupled to the MPC. The PAU can arbitrate the plurality of data requests as a function of the corresponding compute resource priorities.

Abstract: Apparatus and methods implementing a hardware queue management device for reducing inter-core data transfer overhead by offloading request management and data coherency tasks from the CPU cores. The apparatus include multi-core processors, a shared L3 or last-level cache (“LLC”), and a hardware queue management device to receive, store, and process inter-core data transfer requests. The hardware queue management device further comprises a resource management system to control the rate in which the cores may submit requests to reduce core stalls and dropped requests. Additionally, software instructions are introduced to optimize communication between the cores and the queue management device.

Abstract: Method and system for performing data movement operations is described herein. One embodiment of a method includes: storing data for a first memory address in a cache line of a memory of a first processing unit, the cache line associated with a coherency state indicating that the memory has sole ownership of the cache line; decoding an instruction for execution by a second processing unit, the instruction comprising a source data operand specifying the first memory address and a destination operand specifying a memory location in the second processing unit; and responsive to executing the decoded instruction, copying data from the cache line of the memory of the first processing unit as identified by the first memory address, to the memory location of the second processing unit, wherein responsive to the copy, the cache line is to remain in the memory and the coherency state is to remain unchanged.
