The Impact of Parallel Processing on Operating Systems

Parallel File Systems IIT-Computer Science. 12/12/2017 · This term is used in modern operating systems when multiple tasks share a common processing resource (e.g., CPU and Memory). At any time the CPU is executing one task only while other tasks waiting their turn. The illusion of parallelism is achieved when the CPU is reassigned to another task (i.e., What is a distributed system?(cont.) n Michael Flynn (1966) uSISD — single instruction, single data uSIMD — single instruction, multiple data uMISD — multiple instruction, single data uMIMD — multiple instruction, multiple data n More recent (Stallings, 1993) 5 Classification of MIMD Architectures n Tightly coupled ≈ parallel processing uProcessors share clock and memory, run one OS.
