The OMII Software – Demonstrations and Comparisons between two different deployments for Client-Server Distributed Systems
This paper describes the key elements of the OMII software and the scenarios which OMII software can be deployed to achieve distributed computing in the UK e-Science Community, where two different deployments for Client-Server distributed systems are demonstrated. Scenarios and experiments for each deployment have been described, with its advantages and disadvantages compared and analyzed. We conclude that our first deployment is more relevant for system administrators or developers, and the second deployment is more suitable for users’ perspective which they can send and check job status for hundred job submissions
Scientific workflow orchestration interoperating HTC and HPC resources
8 páginas, 7 figuras.-- El Pdf del artículo es la versión pre-print.In this work we describe our developments towards the provision of a unified
access method to different types of computing infrastructures at the interop-
eration level. For that, we have developed a middleware suite which bridges
not interoperable middleware stacks used for building distributed computing
infrastructues, UNICORE and gLite. Our solution allows to transparently
access and operate on HPC and HTC resources from a single interface. Using
Kepler as workflow manager, we provide users with the needed integration of
codes to create scientific workflows accessing both types of infrastructures.Peer reviewe
