A set of configurable sync groupings (which may be referred to as sync zones) are defined. Any of the processors may belong to any of the sync zones. Each of the processor comprises a register indicating to which of the sync zones it belongs. If a processor does not belong to a sync zone, it continually asserts a sync request for that sync zone to the sync controller. If a processor does belong to a sync zone, it will only assert its sync request for that sync zone upon arriving at a synchronisation point for that sync zone indicated in its compiled code set.

A method and apparatus for scaling a Network Based Media Processing (NBMP) workflow on a cloud platform. The method includes obtaining an input workflow including input media stream, determining at least one of scaling type information or transition type information for the input work flow; generating a updated workflow based on the determined at least one of the scaling type information or the transition type information and processing the updated workflow.

An example method of managing exclusive affinity for threads executing in a virtualized computing system includes: determining, by an exclusive affinity monitor executing in a hypervisor of the virtualized computing system, a set of threads eligible for exclusive affinity; determining, by the exclusive affinity monitor, for each thread in the set of threads, impact on performance of the threads for granting each thread exclusive affinity; and granting, for each thread of the set of threads having an impact on performance of the threads less than a threshold, exclusive affinity to respective physical central processing units (PCPUs) of the virtualized computing system.

Approaches in accordance with various embodiments can reduce scheduling delays due to concurrent processing requests, as may involve VSyncs in multi-streaming systems. The software synchronization signals can be staggered relative to each other by offsetting an initial synchronization signal. These software synchronization signals can be readjusted over time such that each synchronization signal maintains the same relative offset, as may be with respect to other applications or containers.

A system includes a memory, at least one physical processor in communication with the memory, and a plurality of threads executing on the at least one physical processor. A first thread of the plurality of threads is configured to execute a plurality of instructions that includes a restartable sequence. Responsive to a different second thread in communication with the first thread being pre-empted while the first thread is executing the restartable sequence, the first thread is configured to restart the restartable sequence prior to reaching a memory barrier.

In a distributed system where a client's call to commit a transaction occurs outside the transaction's lock-hold interval, computation of timestamp information for the transaction is moved to a client library, while ensuring that no conflicting reads or writes are performed between a time of the computation and acquiring all locks for the transaction. The transaction is committed in phases, with each phase being initiated by the client library. Timestamp information is added to the locks to ensure that timestamps are generated during lock-hold intervals. An increased number of network messages is thereby overlapped with a commit wait period in which a write in a distributed database is delayed in time to ensure concurrency in the database.

While scheduled checkpoints are being taken of a cluster of active compute nodes distributively executing an application in parallel, a likelihood of failure of the active compute nodes is periodically and independently predicted. Responsive to the likelihood of failure of a given active compute node exceeding a threshold, the given active compute node is proactively migrated to a spare compute node of the cluster at a next scheduled checkpoint. Another spare compute node of the cluster can perform prediction and migration. Prediction can be based on both hardware events and software events regarding the active compute nodes.

Novel tools and techniques are provided for implementing object-oriented infrastructure-as-code platform (“OOIACP”) and its functionalities. In various embodiments, an OOIACP may receive a request to perform a function from a requesting device. The OOIACP includes a declarative configuration language (“DCL”)-based infrastructure-as-code (“IAC”) software tool that provides structure and data functionalities and a wrapper tool that provides algorithm and sequence functionalities to the IAC software tool to convert the IAC software tool into an object-oriented programming (“OOP”)-based IAC system. The OOIACP uses a run command to perform the requested function, by identifying classes within a class hierarchy associated with the requested function, and initiating a set of procedures in each identified class. Each class and subclass within the class hierarchy has one or more predefined class behaviors, and each subclass inherits class behaviors of classes to which it belongs and of any intermediate subclasses.
