Grid and Cluster Computing are becoming the two main approaches for building large-scale and cost-effective computing infrastructures.
The course aimed to help researchers to understand the Grid key concepts and the role of Grid Computing in computationally intensive problems. This included working with portals, workflow management systems and the Grid middleware. The mooc participants were provided with student accounts and a preconfigured Virtual Machine VM with all the necessary Grid tools installed. If you want to run the examples presented in the video lectures below you will have to request your personal Grid account, see Prerequisites. Please contact helpdesk surfsara.
Grid computing is the use of widely distributed computer resources to reach a common goal. A computing grid can be thought of as a distributed system with non-interactive workloads that involve many files. Grid computers also tend to be more heterogeneous and geographically dispersed thus not physically coupled than cluster computers. Grids are often constructed with general-purpose grid middleware software libraries. Grid sizes can be quite large. Grids are a form of distributed computing whereby a "super virtual computer" is composed of many networked loosely coupled computers acting together to perform large tasks.
Distributed computing is a field of computer science that studies distributed systems. A distributed system is a system whose components are located on different networked computers , which communicate and coordinate their actions by passing messages to one another from any system. Three significant characteristics of distributed systems are: concurrency of components, lack of a global clock , and independent failure of components. A computer program that runs within a distributed system is called a distributed program and distributed programming is the process of writing such programs.
В воздухе пахло жженой пластмассой.
Халохот вырвался из вращающейся двери в тот момент, когда Беккер попытался завести мотоцикл. Убийца улыбнулся и начал поднимать пистолет. Заслонка. Беккер повернул рычажок под топливным баком и снова нажал на стартер. Мотор кашлянул и захлебнулся. - El anillo. Кольцо, - совсем близко прозвучал голос.
