![]() ![]() Multiple-instruction-single-data (MISD) is a rarely used classification. The single-instruction-multiple-data (SIMD) classification does the same process repeatedly over a large data set. The single-instruction-single-data (SISD) classification is entirely sequential execution. ![]() Multiple instructions, multiple data (MIMD) streams Multiple instruction, single data (MISD) stream Single instruction, multiple data (SIMD) stream Single instruction, single data (SISD) stream Flynn’s proposed the below categorization of computer systems: ![]() Traditional way to increase performance is to use multiple computing resources, which can execute in parallel to share a load.Ī classification first introduced by Flynn is most common way of categorizing systems with parallel computing capabilities. Multiple computing resources are utilized simultaneously to solve a computational problem. Parallel computing is an evolution of serial computing, and it attempts to solve many complex and larger problems, for high performance computing. SMP, Scheduling, Parallel, Processes, Operating System 1. The basic objective of the paper is to provide a quick overview of problems that may arise in designing parallel computing operating system. It also elaborates some concerns of Linux scheduler, for shared memory SMPs parallel computing. Parallel computers can be classified according to the level at which the architecture supports parallelism, with multi-core and multi-processor computers The paper proceeds by specifying key design issues of operating system: like processes synchronization, memory management, communication, concurrency control, and scheduling in case of shared memory SMPs. This review paper is intended to address some of the major operating systems’ design issues for shared memory parallel computers like SMPs. Parallel computing attempts to solve many complex problems by using multiple computing resources simultaneously. ![]()
