GlobusWORLD 2011 will be held April 11-12 at Argonne (near Chicago, Illinois, USA). The Globus team successfully launched Globus Online at SC10 in New Orleans last month, showcasing a reliable, secure high-performance file transfer service that is simple to use for grid end-users, developers, and system builders alike. GlobusWORLD 2011 will feature new user success stories, the launch of expanded software-as-a-service capabilities in Globus Online, and updates on Globus Toolkit development. A broader range of tutorials will feature topics that address Globus use and integration, and offer sneak peeks into planned features. Remember to adjust your schedules!
