TL;DR: Vine Toolkit solution addresses some major challenges here such as the synchronization of distributed workflows, establishing a community driven grid environment for the seamless results sharing and collaboration, and integrating with workflow engine and grid security.

TL;DR: This chapter discusses various ideas to improve the performance of Eulag - a numerical solver for all-scale geophysical flows using innovative computing technologies, and presents preliminary results of applying the GPGPU and OpenMP shared memory model to EULag.

TL;DR: This work designs architecture for a quasi-opportunistic supercomputer within the EU-supported project QosCosGrid, and presents the results obtained from studying and identifying the requirements a grid needs to meet in order to facilitate quasi- opportunistic supercomputing.

TL;DR: This work has proposed some extensions to the OGSA‐DAI architecture and successfully implemented new mechanisms enabling secure communication and distributed data integrity along with fine‐grain authorization and policy enforcement to minimize the complexity of the security right management.

TL;DR: This paper aims to present early experiences with computationally demanding applications, development efforts and evaluation of their performance on the new family of Intel Xeon 7500 processors, and confirmed that new hardware solutions can improve the overall application performance.
