Abstract: Techniques are disclosed for reallocating host resources in a virtualized computing environment when certain criteria have been met. In some embodiments, a system identifies a host disabling event. In view of the disabling event, the system identifies a resource for reallocation from a first host to a second host. Based on the identification, the computer system disassociates the identified resource's virtual identifier from the first host device and associates the virtual identifier with the second host device. Thus, the techniques disclosed significantly reduce a system's planned and unplanned downtime.

Abstract: Providing self-resetting multi-producer multi-consumer semaphores in distributed processor-based systems is disclosed. In one aspect, a synchronization management circuit provides a semaphore including a counting semaphore value indicator, a current wait count indicator, and a target wait count indicator. When a consumer completes a wait operation, the synchronization management circuit adjusts the value of the current wait count indicator towards the value of the target wait count indicator, and compares the value of the current wait count indicator to the value of the target wait count indicator. If the value of the current wait count indicator has reached the value of the target wait count indicator, the synchronization management circuit infers that all consumers have observed the semaphore, and accordingly resets both the counting semaphore value indicator and the current wait count indicator to an initial wait value to place the semaphore in its initial state for reuse.

Abstract: Systems and methods are described for reducing cold starts code within a serverless code execution system by providing a set of environments reserved for the code. A frontend distribute calls for execution among a set of manager devices that manage environments in the system, distributed in a manner that groups calls together and attempts to distribute calls of the same group to a stable subset of the manager devices. In the case that a user reduces or eliminates the number of environments reserved for the code, a frontend continues to distribute calls for execution of the code to those environments while they continue to be used. This reduces cold starts that might otherwise occur during reduction or elimination of reserved environments.

Abstract: Dynamic deferral systems and methods providing a means to defer performance of a task for a distributed computing system entity both by the number of work cycles as well as in response to an occurrence of a triggering event. By deferring the scheduling in terms of the number of work-cycles, the memory footprint is reduced as the scheduling matrix uses only one byte to store the number. This approach also takes advantage of the most significant bit of a byte to indicate whether the scheduled job is to be evoked in response to a triggering event.

Abstract: A technique relates to moving a target logical partition. A software application receives a trigger to automatically move the target logical partition from a first system to a second system. The logical partition memory of the target logical partition is transferred from the first system to a coupling facility. In response to completion of transferring the logical partition memory of the target logical partition to the coupling facility, the logical partition memory of the target logical partition is transferred from the coupling facility to the second system.

Abstract: Dynamic generation and implementation of assignment mappings of data items in large data files to distributed processors to achieve objectives such as reduced overall processing time like. Any appropriate key (e.g., character string) can be identified or obtained for each data item in a data file and the file can be segmented into sequential data blocks, where each data block includes a set of data items. The data items in each of a first plurality of the blocks (e.g., sampled block set) may be initially sorted into one of a plurality of key ranges of a search space (each corresponding to a different respective processor) and analyses conducted on the data items totals in each key range. The key range boundaries can be adjusted by accounting for uncertainty in the sample estimates to more evenly distribute data items from all blocks sent to each processor and thereby achieve the objective.

The modification is achieved with minimal unwanted distortions introduced to other portions of the structure to be built by decoupling the global scaling effects on the whole structure from the desired local effects on certain portions.

Abstract: System and methods for automatically scaling compute resources in a compute group. The method includes determining compute capacity required to complete job requests and determining allocable compute capacity available on the compute resources in the compute group. The method further includes calculating a utilization of the compute group based on the required compute capacity and allocable compute capacity and determining whether the calculated utilization is above a first threshold value or below a second threshold value; upon determining that the calculated utilization is above the first threshold value the method calculates a number of compute resources required to bring the utilization below the first threshold value and causes an increase in the number of compute resources in the compute group based on the calculated number. Upon determining that the calculated utilization falls below the second threshold value the method causes a reduction in the number of active compute resources.

Abstract: The present disclosure provides for predictively allocating computing resources based on movement of a simulation agent through a simulation environment, such as in a video game. In order to support the movement of the simulation agent, computing resources may be allocated in various ways. For example, one option may be to transfer data assets associated with the simulation agent from the first computing resource to the second computing resource. Another option may be leave the data assets at the first computing resource and transfer authority over at least a portion of the second region from the second computing resource to the first computing resource. In various embodiments, the way in which the computing resources are allocated may be determined based on various factors, such as resource costs, so that the movement of the simulation agent can be supported with optimal system efficiency.
