Release Notes 5.7

GridWay 5.7 is the new development version of the fifth series of the metascheduler.

Release date: March 31st, 2011.

Modified installation procedure

GridWay core and commands are now configured, built and installed separately from the MADs, which have their own Makefile.

This way, GridWay installation does not depend on the installation of a given middleware.

Randomized Job State Polling

Job state is polled at randomized intervals, to avoid saturation due to multiple simultaneous requests. Moreover, the interval is duplicated when a failure occurs.

CREAM Middleware Access Driver (MAD)

A technology preview of an execution driver for CREAM, the job submission and management interface of gLite, is included in this release.

OGSA-BES Middleware Access Driver (MAD)

A technology preview of an execution driver for OGSA-BES, the OGF specification for job submission and management, is included in this release.
