Abstract

Grid computing is a very promising research area in Computer Science in our days. The ultimate goal is to interconnect large number of heterogeneous resources and services (like processors, storage systems, databases, special devices, etc.) into an abstract resource pool to make them dynamically available for various user communities (represented by virtual organizations) all around the world on demand. The Grid itself denotes the middleware systems and communication protocols that aim to hide the heterogeneous and complex nature of the underlying resources from the end users or from the end user applications.

The LPDS Laboratory of MTA SZTAKI (Computer and Automation Research Institute of the Hungarian Academy of Sciences) has been involved in several national and international Grid research activities and has achieved internationally respected results. The main interests of the laboratory include designing and prototyping program development tools to support high-performance computing in the Grid.

The talk will overview the main features of P-GRADE that can be applied for transparently developing and running applications on both supercomputers, clusters and the Grid. P-GRADE (Parallel Grid Run-time and Application Development Environment) hides the complexity of the Grid from the user and makes the Grid transparent. Users do not have to worry about which service or resource they are accessing - they use the same high-level graphical environment and tools. P-GRADE uses a set of libraries and Grid middleware tools, which together allow applications to access Grid resources without the programmer having to learn the details of the underlying Grid middleware or its APIs. P- GRADE produces a set of high-level application-oriented Grid services such as transparent and automatic application migration, performance monitoring and visualization and workflow management for both end-users and application developers.

Thus they can develop and run applications on the Grid without having to know in advance what the runtime environment will provide. Emphasis will be put on the Grid-specific services of P-GRADE like workflow management and the P-GRADE Grid portal. A real HPC meteorology application developed by the Hungarian Meteorology Service will be used to demonstrate the various facilities and features of P-GRADE throughout the talk.
