[gfarm-announce:00008] Gfarm Version 1.0 release Available

[Osamu Tatebe <o.tatebe@xxxxxxxxxx>]

Hello all,

The Grid Datafarm team is pleased to announce the release of Gfarm
Data Grid middleware, version 1.0.  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 was used for a Trans-Pacific large-scale testbed during
SC2003 last week.  The successful experiment won the Distributed
Infrastructure Award in the high-performance bandwidth challenge.

The software can be downloaded from: http://datafarm.apgrid.org/

Bug tracking system is available at http://datafarm.apgrid.org/bugzilla/

	    and scheduling functions hang.
