Release Announcement for ARC version 0.8.2.1

June 3, 2010


The 0.8.2.1 is an emergency release of the 0.8.2 major ARC release that was created to provide a fix for the critical bug #1944.

The Advanced Resource Connector as of version 0.8.2.1 is an open source software solution that enables production quality computational grids for high throughput computing, encompassing a wide range of size and purpose. The middleware integrates computing resources (typically, computing clusters managed by a batch system) and, to a lesser extent, storage services, making them available via an information system and a common secure grid layer. The middleware builds upon standard open source solutions such as OpenSSL, OpenLDAP and libxml2, as well as some Globus Toolkit 5 pre-WS libraries. It relies on well-tested technologies in creating unique ARC-specific services and tools. ARC developers strive to achieve simplicity, non-invasiveness, high performance, stability and reliability. With release 0.8.2.1 come enhanced scalability and improved performance of computing and information services. ARC middleware is officialy supported on major Linux flavors, and is known to operate smoothly on other Linux systems, with a variety of batch job management systems. Starting from release 0.8.2 several of the new components are also available on Microsoft Windows and Mac OS X platforms.
