Developing CPU scheduling algorithms and understanding their impact in practice can be difficult and time consuming due to the need to modify and test operating system kernel code and measure the resulting performance on a consistent workload of real applications. As processor is the important resource, CPU scheduling becomes very important in accomplishing the operating system (OS) design goal...

PURPOSE To demonstrate the feasibility of real-time phase contrast magnetic resonance (PCMR) assessment of continuous cardiac output with a heterogeneous (CPU/GPU) system for online image reconstruction. MATERIALS AND METHODS Twenty healthy volunteers underwent aortic flow examination during exercise using a real-time spiral PCMR sequence. Acquired data were reconstructed in online fashion us...

Providing QoS is one of the important issues in order to improve the performance of Cellular IP network. Resource reservation is often used in achieving this goal and it is proven to be an effective mechanism so far. Resources of Cellular IP network that can be reserved are bandwidth, buffer and CPU cycles. This paper is proposing a model for router CPU cycle reservation for real-time flows in ...

In order to investigate the role of the dorsomedial and dorsolateral caudate-putamen (CPu) in movement initiation of rats, we examined the effects of quinolinic acid lesions (30 nmol in 1 microliter) in these striatal subregions in a simple reaction time task. Results show that lesions of the dorsomedial, but not of the dorsolateral CPu increased reaction times. These findings provide further e...

In multiprogramming systems i.e. in systems where several processes reside in memory, organization of processes is very important so that CPU always has one to execute. CPU scheduling is the base of multiprogramming operating systems. CPU executes one process at a time and switches between processes to improve CPU utilization. CPU scheduling strategies help in selecting the next process to be e...

As an aid to the study of CPU scheduling algorithms for a single CPU, the author has developed an interactive Java-based simulator that uses graphical animation to convey the concepts of various CPU scheduling algorithms including First-Come, First-Served (FCFS), Round-Robin (RR), Shortest-Job-First (SJF), Shortest-Remaining-Time-First (SRTF), Priority Scheduling, and Multilevel Feedback Queues...
