A philosophical and technical comparison of Legion and Globus

Fault Tolerance in Grid using Ant colony Optimization and Directed Acyclic Graph

“…Table (1) indicates tasks computing cost matrix existing in the program independently on different processors. This matrix called execution time of completion cost matrix (ETC) is entered to the system as another input of problem.As indicated in figure (1), in this paper the computing time for any task, the same as expected execution time is equal with the minimum time of running that task on all processors.In addition, it is assumed that the tasks will be allocated to the resources on non-preemption based and processors may not be allocated to another task until last task is completed.…”

“…In this problem, ants will be put on different nodes of graph. Any ant may choose its next node randomly and by calculating the special probability function according to equation (1). In any repeat in the problem, such choices will be continued to such extent that all nodes could be surveyed.…”

“…Grid computing is resource sharing and problem solving in dynamic virtual organizations throughout several institutions [1]. Using parallel programs is a reliable choice to attaining the higher performance.…”

Comparison Between Cloud and Grid Computing: Review Paper

“…Grimshaw et.al. [28] define grid computing as "coordinated resource sharing and problem solving in dynamic, multi-institution virtual organizations".…”

InteGrade: Um Sistema de Middleware para Computação em Grade Oportunista

“…Tal fase de análiseé devida em parte ao princípio de arquitetura adotado por Legion: construir uma fundação básica sobre a qual os serviços de maior nível da Grade pudessem ser construídos. Tal arquitetura contrasta fortemente com o desenho do Globus Toolkit Versão 2 [GHN04], baseada em um conjunto de serviços razoavelmente independentes, mas curiosamente guarda grande semelhança com o Globus Toolkit Versão 3 e sua arquitetura OGSA/OGSI.…”
