A Disk Scheduling Simulator tool. With an intuitive GUI interface and command line functionality. Built using both VC and VB. Currently supports SSTF,LOOK,CLOOK,SCAN and CSCAN algorithms. Rotational latency is also optionally supported.
Trio extends the existing Linux scheduler to support proportional-share scheduling using a schedulingalgorithm, called Distributed Weighted Round-Robin (DWRR). It allows users to control shares of CPU time for any thread or group of threads.
