[lsg-rg] GridWay development release

[Eduardo Huedo Cuesta]

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.
