End-user Information
The access to the QosCosGrid middleware may be realised in two ways depending on user requirements. The first option is based on using command-line tools delivered with the core software. It requires specific knowladge about Grid infrastructure and may be difficult for particular scientists. The second way of using QosCosGrid middleware is an utilization of dedicated Science Gateways.
QosCosGrid Science Gateways
The advanced graphic and multimedia oriented user interfaces (GUIs) designed for scientists and engineers could change the way end-users collaborate, deal with advanced simulations, share results and work together to solve challenging problems. Moreover, future science and engineering gateways will influence they way end-users will access not only their data, but also control and monitor their demanding computing simulations over the Internet. To allow end-users to interact remotely with future supercomputers and large-scale computing environments in a more visual manner we developed a web tool called Vine Toolkit. Technically speaking, Vine Toolkit is a modular, extensible and easy-to-use tool as well as high-level Application Programmer Interface (API) for various applications, visualization components and building blocks to allow interoperability between many different grid and supercomputing technologies. It supports Adobe Flex and BlazeDS technologies to allow developers to create advanced, rich web applications similar to many stand-alone GUIs. Additionally, Vine Toolkit has been integrated with well-known open source web frameworks, such as Liferay and GridSphere. Using the enhanced version of Vine Toolkit we created a new interface called QosCosGrid Science Gateway. The Vine based QosCosGrid Science Gateway consists of general part showing and monitoring computational resource characteristics as well as a set of domain specific web applications developed for certain complex system use cases. Therefore, end-users are able to use only web browsers to create and submit their complex simulations.
QosCosGrid Icon
For Windows users we prepared a lightweight application called QCG-Icon. Its allows to submit MATLAB scripts (we plan to support also other applications) to remote computing clusters in a way that resembles local execution. Thanks to the QCG-Icon the HPC resources are just one-click away from your desktop.
Other tools
Moreover, in the PL-Grid project, an additional client, enabling the mobile access to the QosCosGrid middleware was implemented. The QCG-Mobile application is written in Java Micro Edition and allows for most common operations like job submission and control. Its leverages SOAPoverXMPP to receive asynchronous notification about the job states. We also plan to provide QCG-Mobile for the Android platform.
