Release Notes 5.4

GridWay 5.4, which is also shipped with GT4.2.0, is a new stable version with increased functionality, including support to access the NorduGrid infrastructure, new bindings for DRMAA and support for DAGMAN workflows.

Release Date: July 9th, 2008

Integration with major Grid Infrastructures

Following the trend from previous releases, GridWay is capable of integrate with another major infrastructure: NorduGrid. Drivers for Execution and Transfer are included in this release.

New DRMAA bindings for scripting languages

Previous GridWay releases come with support for C and Java bindings implementing the DRMAA standard. Scripting languages are interesting from the point of view of rapid application prototyping among others. From dsa-research.org we believe this to be an interesting aspect, and that is why GridWay includes bindings to access the DRMAA standard from scripting languages such as Perl, Ruby and Python.

Support for DAGMAN workflows

There is an increasing interest from the scientific community to be able to run complex workflows on a Grid environment. An almost de-facto standard to represent DAG workflows is Condor DAGMAN. In this development release GridWay includes a new workflow launcher (gwdag) that handles this kind of workflows.
