Little emphasis has been placed on implementing and executing meteorological models on computational grids, mainly because they require long executions that mix sequential and parallel execution in grid environments with high performance computing (HPC) clusters.
Cluster virtualization is a promising approach to construct customized execution environments for Grid users.
The user must only specify, by global criteria, the high level policies and submit the application for execution over the Grid.
A parallel adaptation of this algorithm is proposed to address the associated computational requirements through execution in a Grid computing environment.
It took me a while to settle in to the execution of the grid (I was a bit thrown by the way "LIKE A ROLLING STONE" was broken up), but once I did, I found myself humming along with Peter A. Collins's tribute to the ROLLING STONE list of the "500 Greatest Songs of All Time".
The components that manage and control the execution in the Grid environment interact with the suit of the SLA-related services exchanging information that is used to provide the quality framework of the execution with respect to the agreed contractual terms.
This paper presents a scientific workflow based approach to facilitate the inside-out enzyme design process in the Grid execution environment by providing features such as resource consolidation, task parallelism, provenance tracking, fault tolerance and workflow reuse, which results in an automated, pipelined, efficient, extensible, stable, and easy-to-use computational process for enzyme design.
Even when a failure occurred, data movement and climatology execution on another grid node, from the point the simulation stopped, worked as expected.
This model is closer to job execution on the grid rather than the model more common in the cloud which is reserving a VM with specific resource requirements and then running tasks on them.
The integrated simulation system, (incorporating image processing, visualization, grid execution and other technical facilities) has been termed "Oncosimulator" [25].
