A Review on multithreading processes and threads in multiple cores CPU

Abstract

The objective of our research is to analyze job handling process of CPU in different circumstances. Here we would analyze how CPU reacts in case of single task & in case when it switches among multiple tasks & how multiple task are managed as thread within a multi-core processor to execute multiple processes or threads concurrently, appropriately supported by operating system. This approach differs from multiprocessing, as with multithreading processes & threads have to share resources of a single or multiple cores: computing units, CPU caches, & translation lookaside buffer. A scheduler may aim at one of several goals, for example, maximizing throughput, minimizing response time or minimizing latency, maximizing fairness (equal CPU time to each process, or more generally appropriate times according to priority & workload of each process). All these goals often conflict thus a scheduler would implement a suitable compromise. Preference is given to any one of concerns mentioned above, depending upon user's needs & objectives.
