A computational grid is a widespread computing environment that provides huge computational power for large-scale distributed applications. One of the most important issues in such an environment is resource management. Task assignment as a part of resource management has a considerable effect on the grid middleware performance. In grid computing, task execution time is dependent on the machine...

Scheduling a collection of tasks on a multiprocessor, consisting of p processors, that minimizes the maximum completion time has attracted a lot of attention in the literature [12]. In this paper, we introduce a new problem of scheduling a task graph on a multiprocessor, called the parallelizable dependent task scheduling problem. Associated with each task, we are given the time it takes to run...

the purpose of this study was to investigate the impact of weblog task assessment on iranian efl learners’ reading ability. to this purpose, a group of 30 english language students (both male and female) in rozaneh language institute in najafabad were selected based on their performance on the opt. the researchers tried to select a homogeneous sample in terms of age factor and proficiency level...

framed in a cognitive approach to task-supported l2 vocabulary learning, the present study used a pedagogical approach to investigate the relative effectiveness of tasks with different involvement loads on the vocabulary knowledge of iranian efl learners. the goal was to investigate the way that the construct of involvement load is related to the input hypothesis (krashen, 1985) and the output ...
