SUMMARY 53 Parallel Computing: Parallel computing is a type of computation in which many calculations or the execution of processes are carried out simultaneously. Types of Parallelism: • Bit-Level Parallelism • Instruction level Parallelism • Task Parallelism www.cuidol.in Unit-1 (MCA635) All right are reserved with CU-IDOL
SUMMARY 54 Hardware Architecture of Parallel Computing The hardware architecture of parallel computing is disturbed along the following categories as given below : 1. Single-instruction, single-data (SISD) systems 2. Single-instruction, multiple-data (SIMD) systems 3. Multiple-instruction, single-data (MISD) systems 4. Multiple-instruction, multiple-data (MIMD) systems Performance Metrics: 1. Performance metrics for Processor/Cores 2. Performance metrics for Parallel applications Parallel Programming Model: A parallel programming model is an abstraction of parallel computer architecture, with which it is convenient to express algorithms and their composition in programs. www.cuidol.in Unit-1 (MCA635) All right are reserved with CU-IDOL
