Hello all,
We are pleased to announce the release of Gfarm Data Grid middleware,
version 1.0.1. Gfarm is a reference implementation of the Grid
Datafarm architecture designed for Petascale Data-intensive computing.
It provides a global file system using local disks of cluster nodes,
and supports data-parallel execution via file-affinity scheduling.
This release includes performance improvement, fault tolerance
improvement, and bug fixes by extensive testing. We strongly
encourage all to upgrade to this version.
The software can be downloaded from: http://datafarm.apgrid.org/
Bug tracking system is available at http://datafarm.apgrid.org/bugzilla/
