A Visual Development Environment for Meta-Computing Applications
نویسندگان
چکیده
Gaspard is a visual programming environment devoted to the development and control of scientific parallel applications. The two paradigms of parallel programming (task and data parallelism) are mixed in Gaspard: a hierarchy of task graphs operates on array flows. These two levels are mixed in a common metaphor. An application is designed as a printed circuit: the programmer specifies tasks as boards or chips and instantiates tasks by plugging them into slots. The number crunching applications developped using Gaspard are deployed on metacomputing platforms. The visual specification of the application mapping may be dynamically modified at runtime according to the information provided by Gaspard.

Integrated modeling and solving the resource allocation problem and task scheduling in the cloud computing environment
Cloud computing is considered to be a new service provider technology for users and businesses. However, the cloud environment is facing a number of challenges. Resource allocation in a way that is optimum for users and cloud providers is difficult because of lack of data sharing between them. On the other hand, job scheduling is a basic issue and at the same time a big challenge in reaching hi...

متن کاملAn Efficient Genetic Algorithm for Task Scheduling on Heterogeneous Computing Systems Based on TRIZ
An efficient assignment and scheduling of tasks is one of the key elements in effective utilization of heterogeneous multiprocessor systems. The task scheduling problem has been proven to be NP-hard is the reason why we used meta-heuristic methods for finding a suboptimal schedule. In this paper we proposed a new approach using TRIZ (specially 40 inventive principles). The basic idea of thi...
