Unit 5 Topics Covered

Complete syllabus-based topics of ACA Unit 5.

Parallel Programming Models

Models used to write programs that can run on multiple processors simultaneously.

Shared-Variable Model

Parallel processes communicate by reading and writing shared variables in common memory.

Message-Passing Model

Processes communicate by sending and receiving messages, commonly used in distributed memory systems.

Data-Parallel Model

The same operation is applied to many data items simultaneously using parallel processors.

Object-Oriented Model

Parallelism is represented using objects that communicate and execute methods concurrently.

Functional and Logic Models

Programming approaches where computation is based on functions, rules and logical relations.

Parallel Languages

Languages or language extensions designed to express parallelism in programs.

Parallel Compilers

Compilers that detect, optimize and translate parallel code for execution on parallel systems.

Language Features for Parallelism

Features like task creation, synchronization, communication, shared variables and parallel loops.

Parallel Programming Environment

Environment that provides libraries, runtime support and debugging tools for parallel programming.

Software Tools

Tools used for program development, debugging, profiling and performance analysis.

Parallel Software Environments

Complete platforms that support development and execution of parallel applications.
