What is bulk synchronous parallel BSP model?

Bulk Synchronous Parallel (BSP) is a programming model and computation framework for parallel computing. Computation is divided into a sequence of supersteps. In each superstep, a set of processes, running the same code, executes concurrently and creates messages that are sent to other processes.

How bulk synchronous parallel BSP model is related to the PRAM model?

The bulk synchronous parallel (BSP) model was developed by Leslie Valiant in the 1980s. The BSP model is intended as a bridging model between parallel hardware and software. It is an elegant and simple model that has a small and easy to understand interface.

What is BSP programming?

In BSP, a parallel program runs across a set of virtual processors (called processes to distinguish them from physical processors), and executes as a sequence of parallel supersteps separated by barrier synchronizations. Each superstep is composed of three ordered phases, as shown in Fig.

What is BSP library?

BSPlib is a small communications library for bulk synchronous parallel (BSP) programming which consists of only 20 basic operations. The library enables programming in two distinct styles: direct remote memory access (DRMA) using put or get operations, and bulk synchronous message passing (BSMP).

What is PRAM in parallel computing?

Definition. The Parallel Random Access Machine (PRAM) is an abstract model for parallel computation which assumes that all the processors operate synchronously under a single clock and are able to randomly access a large shared memory.

What is BSP stm32?

The BSP (board support package) drivers are part of the STM32Cube MCU and MPU Packages based on the HAL drivers, and provide a set of high-level APIs relative to the hardware components and features on the Evaluation boards, Discovery kits and Nucleo boards delivered with the STM32Cube MCU and MPU Packages for a given …

What are the constraints of pram?

Constrained on PRAM Model: Bounded size of a machine word and/or memory cell: The parameter of memory cell in PRAM model is presenting the size of a machine word. Bounded number of processors: If the number of threads of execution is higher, processors may interleave several threads sometime it named as a small PRAM.

Which is more powerful model in pram?

The computational powers of the different PRAM versions are relatively minor, but it can be shown that the CRCW PRAM is strictly more powerful than the CREW PRAM, which is strictly more powerful than the EREW PRAM.

Is BSP a government agency?

The Bangko Sentral ng Pilipinas (BSP) is the central bank of the Republic of the Philippines. The BSP enjoys fiscal and administrative autonomy from the National Government in the pursuit of its mandated responsibilities.

What is a BSP UE4?

Purpose of BSP is to blockout the initial geometry of a level or environment for testing; to establish scale, layout, flow and spatial relationship of architecture – for this use BSP brushes. BSP brushes are simple, primitive geometric shapes available to use right inside the UE4 editor.

What does BSP include?

The BSP often includes the bootloader (e.g., Das U-Boot, Barebox, etc.), a Hardware Abstraction Layer (HAL) or an embedded OS (e.g., Linux, ThreadX, Integrity® RTOS, VxWorks), peripheral drivers, and various utilities. Not all boards have BSPs, however.

What is bulk synchronous parallel (BSP)?

The bulk synchronous parallel (BSP) abstract computer is a bridging model for designing parallel algorithms. It serves a purpose similar to the parallel random access machine (PRAM) model. BSP differs from PRAM by not taking communication and synchronization for granted.

What is a BSP abstract computer?

The bulk synchronous parallel (BSP) abstract computer is a bridging model for designing parallel algorithms. It is similar to the parallel random access machine (PRAM) model, but unlike PRAM, BSP does not take communication and synchronization for granted.

When was the Multi-BSP model published?

Valiant developed an extension to the BSP model in the 2000s, leading to the publication of the Multi-BSP model in 2011. In 2017, McColl developed a major new extension of the BSP model that provides fault tolerance and tail tolerance for large-scale parallel computations in AI, Analytics and high-performance computing (HPC).

What is an example of decomposable BSP?

One example of this is the decomposable BSP model. The model has also been used in the creation of a number of new programming languages and interfaces, such as Bulk Synchronous Parallel ML (BSML), BSPLib, Apache Hama, and Pregel.
