On behalf of the Organizing Committee, I’m pleased to invite you to participate in the Pacific Rim Application and Grid Middleware Assembly (PRAGMA) 25th Workshop, which will be held in Beijing from 16-18 October 2013. We expect to share techniques and experiences during the workshop, and explore more opportunities to enhance sustained collaborations. Your active participation and contributions will be of great benefit to all participants and make the PRAGMA 25th Workshop truly successful. PRAGMA is an open organization in which leading institutions around the Pacific Rim collaborate to advance the applications on Grid and Cloud, as well as to deploy the needed infrastructure. CNIC has actively participated as a founding member of PRAGMA since the inaugural PRAGMA Workshop in 2002, and now aims to enhance the impact of the collaboration. Please feel free to contact me if you need any information. We look forward to seeing you in October.
