Shortest access time first

SpletThe traditional shortest access time first (SATF) algorithm greedily schedules the request that is closest to the current disk head position [ 16, 23 ]. It takes both seek and rotational latency into consideration. We now extend this algorithm for eager-writing, and we call this extension the SATF-EW algorithm. Splet26. mar. 2024 · Preemptive SJF Scheduling is sometimes called Shortest Remaining Time First algorithm. Advantages • It gives superior turnaround time performance to shortest process next because a short job is given immediate preference to a running longer job. • Throughput is high.

Eager-writing-based Shortest Access Time First Scheduling

Splet09. jun. 2024 · Shortest Job First (SJF) Scheduling Algorithm is based upon the burst time of the process. The processes are put into the ready queue based on their burst times. In this algorithm, the process with the least burst time is processed first. The burst time of only those processes is compared that are present or have arrived until that time. Splet21. okt. 2024 · Q2. A cache memory that has a hit rate of 0.8 has an access latency 10 ns and miss penalty 100 ns. An optimization is done on the cache to reduce the miss rate. However, the optimization results in an increase of cache access latency to 15 ns, whereas the miss penalty is not affected.
