bulksynchronous

Bulk synchronous, often abbreviated as BSP, is a parallel computing model. It divides computation into phases, where each phase consists of a local computation phase followed by a global communication phase. All processors perform their local computations independently. After the local computation, processors can exchange data with each other. This communication phase is synchronized, meaning all processors must complete their communication before proceeding to the next local computation phase. The BSP model aims to provide a programming abstraction that simplifies parallel algorithm design while achieving good performance on distributed memory systems. It decouples the computation from communication, allowing for more predictable execution times. Developers write code for the local computation and then specify the communication patterns needed between phases. This structured approach helps manage the complexities of parallel execution. The model is characterized by its three main components: computation, communication, and synchronization. The bulk synchronous parallel model has been influential in the development of parallel programming languages and libraries.
