Analysis of an algorithm helps us determine whether the algorithm is useful or not. Chapters 1 and 2 cover two classical theoretical models of parallel com putation. In general, major characteristics that affect parallel system performance are clock speed, size and number of registers, number of concurrent paths to memory, instruction issue rate, memory size. Summary focusing on algorithms for distributedmemory parallel architectures, parallel algorithms presents a rigorous yet accessible treatment of theoretical models of parallel computation, parallel algorithm design for homogeneous and heterogeneous platforms, complexity and performance analysis, and essential notions of scheduling. Performance analysis of parallel algorithms engineers. To behaviour analysis, all overheads that have the influence to performance of parallel algorithms architecture, computation, communication, etc.
But performance can be measured in a variety of ways. Pdf performance analysis of parallel sorting algorithms. A parallel system is the combination of an algorithm and the parallel architecture on which it is implemented. Todays the parallel algorithms are focusing on multicore systems. Parallel processing involves utilizing several factors, such as parallel architectures, parallel algorithms, parallel programming lan guages and performance analysis, which are strongly interrelated. Most of todays algorithms are sequential, that is, they specify a sequence of steps in which each step consists of a single operation. Performance optimization of parallel algorithms request pdf. Download citation performance analysis of parallel algorithms a grid is a collection of individual machines. The current multicore architectures have become popular due to performance, and efficient processing of multiple tasks simultaneously. These algorithms are well suited to todays computers, which basically perform operations in a sequential fashion. One of the goals in highperformance computing hpc is to achieve the best possible performance from parallel computers.
