Therefore, the subject disclosure has more values for promotion and application.

Abstract: A streaming engine employed in a digital data processor specifies a fixed read only data stream defined by plural nested loops. An address generator produces address of data elements. A steam head register stores data elements next to be supplied to functional units for use as operands. The streaming engine fetches stream data ahead of use by the central processing unit core in a stream buffer constructed like a cache. The stream buffer cache includes plural cache lines, each includes tag bits, at least one valid bit and data bits. Cache lines are allocated to store newly fetched stream data. Cache lines are deallocated upon consumption of the data by a central processing unit core functional unit. Instructions preferably include operand fields with a first subset of codings corresponding to registers, a stream read only operand coding and a stream read and advance operand coding.

Abstract: Systems and methods for branch prediction include detecting a subset of branch instructions which are not fixed direction branch instructions, and for this subset of branch instructions, utilizing complex branch prediction mechanisms such as a neural branch predictor. Detecting the subset of branch instructions includes using a state machine to determine the branch instructions whose outcomes change between a taken direction and a not-taken direction in separate instances of their execution. For the remaining branch instructions which are fixed direction branch instructions, the complex branch prediction techniques are avoided.

Abstract: Techniques are disclosed for implementing an extensible, light-weight, flexible (ELF) processing platform that can efficiently capture state information from multiple threads during execution of instructions (e.g., an instance of a game). The ELF processing platform supports execution of multiple threads in a single process for parallel execution of multiple instances of the same or different program code or games. Upon capturing the state information, one or more threads may be executed in the ELF platform to compute one or more actions to perform at any state of execution by each of those threads. The threads can easily access the state information from a shared memory space and use the state information to implement rule-based and/or learning-based techniques for determining subsequent actions for execution for the threads.

Abstract: Fault tolerant and fault detecting multi-threaded processors are described. Instructions from a program are executed by both a master thread and a slave thread and execution of the master thread is prioritized. If the master thread stalls or reaches a memory write after having executed a sequence of instructions, the slave thread executes a corresponding sequence of instructions, where at least the first and last instructions in the sequence are the same as the sequence executed by the master thread. When the slave thread reaches the point at which execution of the master thread stopped, the contents of register banks for both the threads are compared, and if they are the same, execution by the master thread is allowed to continue, and any buffered speculative writes are committed to the memory system.

Abstract: Systems and methods are described for managing initialization of virtual machine instances within an on-demand code execution environment or other distributed code execution environment. Such environments utilize pre-initialized virtual machine instances to enable execution of user-specified code in a rapid manner, without delays typically caused by initialization of the virtual machine instances. However, because the number of pre-initialized virtual machine instances maintained at an on-demand code execution environment is typically limited, insufficient number of pre-initialized virtual machine instances may be available at the on-demand code execution environment during times of heavy use. Embodiments described herein utilize pre-trigger notifications to indicate to the on-demand code execution environment that subsequent requests to execute user-specified code are likely to occur.

Abstract: Systems and methods for efficiently protecting simultaneous access to user-space shared data by multiple threads using a kernel structure is disclosed. Further, a mechanism within a spinlock allows reduction of the performance and power interference associated with the improved spinlock.

The improved spinlock allows a thread to enter a power saving state and the critical section to instruct a PCU to allocate a headroom power budget exclusively to the core that executed the instruction. The improved spinlock also provides saving in dynamic power during clock gated of the CPU resources and dynamic and static power during power gated of the CPU resources.

Abstract: A host system defines an event having a pool. The event is contingent on an outcome. The host system receives event data such as a stake value, a certainty value, and content data from network entities coupled to the network.

The host system determines outcome data and an actual allotment for the active network entities based on the outcome data. The host system generates and communicates results data to be displayed. The host system generates a command to allot respective winnings to the appropriate network entities, by transferring winnings to a beneficiary account.

Abstract: Technologies are described for protecting compute resources during outage conditions. For example, when an outage condition is detected, currently allocated compute resources can be protected by not releasing them in response to the outage condition. For example, a load pattern representing historical usage of compute resources by a computer service can be obtained. A predicted load pattern of compute resources can be generated based on the obtained load pattern. An outage condition related to the computer service can then be detected based on the predicted load pattern. In response to detecting the outage condition, compute resources can be protected and not released in response to the outage condition.

Abstract: A remote procedure call channel for interprocess communication in a managed code environment ensures thread-affinity on both sides of an interprocess communication. Using the channel, calls from a first process to a second process are guaranteed to run on a same thread in a target process. Furthermore, calls from the second process back to the first process will also always execute on the same thread. An interprocess communication manager that allows thread affinity and reentrancy is able to correctly keep track of the logical thread of execution so calls are not blocked in unmanaged hosts. Furthermore, both unmanaged and managed hosts are able to make use of transparent remote call functionality provided by an interprocess communication manager for the managed code environment.

Abstract: The flow of events though an event-analysis system is controlled by a number of event throttles which filter events, prioritize events and control the rate at which events are provided to event-processing components of the event-analysis system. Incoming events to the event-analysis system are associated with a profile, and a metrics engine generates metrics based on the incoming events for each profile. The flow of events to the metrics engine is controlled on a per profile basis, so that excessive generation of new metrics and new profiles is limited. If the system from which the events originate is compromised, metrics associated with compromised profiles may be frozen to avoid corrupting existing metrics. Processing of events and anomalies by analysis engines within the event-analysis system may be delayed to allow the accumulation of metrics necessary for accurate analysis.

Abstract: Technologies are described herein for differentiating normal operation of an application program from error conditions to predict, diagnose, and recover from application failures. Access to resources by the application program is monitored, and resource access events are logged. Resource access patterns are established from the logged resource access events utilizing computer pattern recognition techniques.

In addition, sequences of resource access events that deviate from the established resources access patterns are correlated with an error condition based on a temporal proximity to the time of occurrence of the error to provide diagnostic information regarding the error.
