In recent years, there has been a growing interest in cloud computing as a means to enhance user access to shared computing resources, including software and hardware, through the internet. However, the efficient utilization of these cloud resources has been a challenge, often resulting in wastage or degraded service performance due to inadequate scheduling. To overcome this challenge, numerous researchers have focused on improving existing Priority Rule (PR) cloud schedulers by developing dynamic scheduling algorithms, but they have fallen short of meeting user satisfaction. In this study, we introduce a new PR scheduler called Priority Based Fair Scheduling (PBFS), which takes into account key parameters such as CPU Time, Job Arrival Time, and Job Length. We evaluate the performance of PBFS by comparing it with five existing algorithms, and the results demonstrate that PBFS surpasses the performance of the other algorithms. the experiment was conducted using the CloudSim simulator, utilizing a dataset of 300 and 400 jobs. In order to assess the performance, three key metrics were employed: flow time, makespan time, and total tardiness. these metrics were chosen to evaluate and analyze the effectiveness of the proposed scheduling algorithm.

To understand software we must go beyond the techniques and methodologies we have so carefully and painfully crafted, e. g. , high level languages, structured programming, data structures and types, semaphores, functional programming, etc. the author believes that the word 'software' obscures the issues that dominate our concerns and he chooses the word 'organithm' to identify that class of programs we study in softwareengineering. the major issue of softwareengineering environments is not how to ease our task of programming systems but how to accelerate the rate at which improvement in internal function can be obtained without unduly jeapordizing the external functions of an organithm and with maximizing the use of organithms to perform reorganization.

A programming tool is described for real-time embedded systems implemented by multiple tasks. the tool, called TRUE, performs the allocation of tasks by transformation of the program the user has written. TRUE reads the program and the requirements about its response time. TRUE transforms the program applying rules based on the requirements. then the program is translated into a code for operating system I-TRON. I-TRON is the original real-time operating system for 32-bit microprocessors. A description is given of the implementation of TRUE and an example of its use is presented.
