Dear LSG-RG colleagues, Below you will find the official announcement of the GridWay framework release. You can find some use cases in http://www.gridway.org/usecases.php, including a Bioinformatics application for protein structure prediction and thermodynamic analysis. Don't hesitate to check the rest of the web site and download the software. Best regards, Eduardo Huedo ======================================================================== GRIDWAY PROJECT TO RELEASE GRIDWAY 4.0 DEVELOPMENT RELEASE The GridWay Team is proud to announce the development release of GW4.0, which incorporates improved functionality and robustness for interacting with the Globus Toolkit services. More information and download at http://www.gridway.org All components developed as part of the GridWay framework are released as "open source" under the GPL license to encourage innovation and pass full freedom to our users. BENEFITS The GridWay framework provides a submission agent that incorporates the runtime mechanisms needed for transparently executing jobs in a Globus-based Grid. Its modular architecture for job adaptation to a dynamic environment offers the following benefits: - Easy to deploy: GridWay is a client tool that does not require new services, apart from Globus basic services. - Easy to extend and adapt: GridWay modules allow its communication with the Grid services available in a given testbed. In fact, it could be used as a building block for much more complex service-oriented. - Easy to use: It is not bounded to a specific class of application generated by a given programming environment, which extends its application range and allows reusing of existing software. - Easy to scale: Its decentralized architecture gives the possibility of boosting scalability. REQUIREMENTS GridWay framework does not require new system software to be installed in the Grid resources apart from Globus Toolkit services. The framework is currently functional on any Grid testbed based on the Globus Toolkit. The client computer must reach the following requirements: - UNIX-like Operating System (i.e. Linux) - A running Globus installation, version 2.4-3.9.3 GridWay uses the following Globus Toolkit services: - Pre-WS and WS GRAM - GridFTP - MDS, when necessary by the Resource Selector FEATURES The GridWay framework offers the following functionality: - Unix-like: GridWay uses commands very similar to those found on Unix systems and resource management systems like PBS or SGE. - Job control: With GridWay you can submit, kill, migrate, watch and wait for jobs. Also, you can submit an array of jobs. - Error detection: GridWay automatically detects when a job has failed, and allows the user to abort, retry o migrate it to a new machine. - Log information: Most relevant information about the jobs can be obtained in the several log files that GridWay generates. - Programming: DRMAA subset support to develop distributed applications. -- ************************************************** Eduardo Huedo Cuesta Laboratorio de Computación Avanzada, Simulación y Aplicaciones Telemáticas Centro de Astrobiología (CSIC-INTA) Ctra. de Ajalvir Km 4 28850 Torrejón de Ardoz, Madrid Spain Tel: +34 91 520 64 28 Fax: +34 91 520 10 74 Email: huedoce@inta.es Web: http://www.cab.inta.es/~huedoce **************************************************
