The P-GRADE Grid Portal was software for web portals to manage the life-cycle of executing a parallel application in grid computing. It was developed by the Laboratory of Parallel and Distributed Systems (LPDS) at the Hungarian Academy of Sciences, Hungary.

Contents

Features

By building onto the GridSphere portal framework, the P-GRADE Portal hides details of Grid systems with high-level interfaces that can be integrated with middleware. It offers portlet based access to the following services:

  • definition of grid environments
  • creation and modification of workflow applications
  • management of grid certificates
  • controlling and execution of workflow applications on grid resources
  • monitoring and visualization of workflows and their component jobs.

    • The P-GRADE Portal allows multi-user development and execution of workflows, and also provides support for workflow level grid interoperation.

    The portal supports various middleware technologies including Globus Toolkit, EGEE (LCG or gLite) and Advanced Resource Connector.

    License and support

    The P-GRADE Portal is developed under the GNU General Public License. Online tutorials videos and documents are available on the P-GRADE Portal site.

    A release of P-GRADE Grid Portal is version 2.10 .

    The 2.9 version introduced features such as Portable Batch System (PBS) and Platform LSF cluster support, EDGes 3G Bridge resource support, local PS port support and extended NorduGrid (ARC) support.

    Installations

    The P-GRADE Portal served grid communities in research and industry, providing access to Grids including:

  • EGEE Grids - through the P-GRADE Multi-Grid portal
  • South-Eastern European Grid - through the P-GRADE Multi-Grid portal
  • NGS Grid (UK) - through the NGS P-GRADE GEMLCA Portal
  • The Belgian Grid for Research (operated by BELNET)- through the BEgrid Portal
  • KnowledgeGRID Malaysia (operated by MIMOS) - through the KnowledgeGRID Malaysia P-GRADE Portal
  • CLGrid (Chile)- through the CLGrid Portal
  • and others, listed on the P-Grade Portal homepage.

    • Applications

    Application specific portals can be created by adding application specific portlets to P-GRADE portal, omitting some generic purpose portlets and hiding the underlying workflow within an application specific portlet.

    Applications include:

  • The parallel version of MadCity, a discrete time-based traffic simulation, developed by the University of Westminster and MTA-SZTAKI. In this case the legacy code of MadCity is deployed in a service-oriented Grid architecture and accessed through a user-friendly Web interface
  • Parallelization and gridification of air pollution forecast on the HUNGRID infrastructure, with P-GRADE Portal providing a flexible and unified way for parallel application development and multi-grid development
  • Gridification of OMNeT++, a public-source, component-based, modular, discrete event simulation environment. OMNeT++ is frequently used in a wide area of simulation applications due to its strong GUI support and embeddable simulation kernel. The P-GRADE Portal environment was successfully integrated with the OMNeT++ simulation framework to enable large-scale grid resources to the simulation user community, providing significant performance increase for OMNeT++-based simulations.
  • Since 2008 applications were listed on the LPDS Grid Application Support Centre web site.

    • The Grid Application Support Centre (GASuC) was established in 2008 within the Laboratory of Parallel and Distributed Systems and supported as part of the European Grid Infrastructure. GASuC provides assistance in porting legacy applications onto grid infrastructures.
