Abstract: A method includes receiving, by a producer thread of a plurality of producer threads, an offer request associated with an item. The producer thread increases a sequence and determines (i) a chunk identifier of a memory chunk from a pool of memory chunks and (ii) a first slot position in the memory chunk to offer the item. The producer thread also writes the item into the memory chunk at the first slot position. Then, a first consumer thread of a plurality of consumer threads determines the first slot position of the item and consumes the item at the first slot position. A second consumer thread consumes another item at a second slot position in the memory chunk and recycles the memory chunk.

Abstract: The technology disclosed herein enables a processor that processes instructions synchronously in accordance with a processor clock to identify a first instruction specifying an asynchronous operation to be processed independently of the processor clock. The asynchronous operation is performed by an asynchronous execution unit that executes the asynchronous operation independently of the processor clock and generates at least one result of the asynchronous operation. A synchronous execution unit executes, in parallel with the execution of the asynchronous operation by the asynchronous execution unit, one or more second instructions specifying respective synchronous operations. Responsive to determining that the asynchronous execution unit has generated the at least one result of the asynchronous operation, the processor receives the at least one result of the asynchronous operation.

Abstract: A virtual machine's (VM's) usage of a resource over a first time period may be monitored to determine a load pattern for the VM. A time series analysis of the load pattern may be performed to generate a predictive resource usage model, the predictive resource usage model indicating one or more predicted variations in the usage of the resource by the VM over a second time period. A predicted resource usage of the VM at a future time that is within the second time period may be determined based, at least in part, on the predictive resource usage model. An amount of the resource to allocate to the VM at a current time may be determined based, at least in part, on the predicted resource usage of the VM at the future time and the actual resource usage of the VM at the current time.

Abstract: Embodiments of the present disclosure provide techniques for seamlessly switching between a classical controller and a quantum controller that both implement an application, based on which controller is better suited for processing a received request for functionality of the application. The classical controller and the quantum controller both implement the same logic for the application, and the classical controller interfaces with a model and a view as part of a model, view and controller (MVC) framework. A Quantum Model View Controller (QMVC) service determines whether the request is to be processed by the classical or quantum controller. In response to determining that the request is to be processed by the quantum controller, the QMVC service diverts the request to the quantum controller and provide a first application program interface (API) gateway between the quantum controller and the model and a second API gateway between the quantum controller and the view.
