This is the first GridWay release since it entered the Globus incubator project. It is mainly a maintenance release with no major features, but includes many bug fixes and minor enhancements.
Release Date: November 17th, 2006
This release includes new functionality in the following GridWay commands:
You can find out more information in the commands help (-h option) or in the command reference guide.
The retrying requests of the Execution and Transfer MADs has been improved. GridWay follows a linear back-off retry strategy in case of MAD failures, which has been implemented at the operation level.
Also development settings has been removed from MADs. Moreover the MADs are now executed with a low priority (using nice values).
When a resource fails, GridWay now implements an exponential linear back-off strategy at resource level (and per each user), henceforth resources with persistent failures are discarded (for a given user).
Also the scheduler module has been re-design and coded from scratch to improve its scalability. Now an asynchronous scheduler to GW communication pattern is followed. Moreover its internal structures has been modified to include easy to use scheduling policies (as the scheduler skeleton has not been very popular among GridWay users). Note. These new policies will be available in version 5.2.
From this release onwards GridWay won't use Storage Elements to transfer files by default. Now transfer and execution are performed as follows:
