Dear OGF working group members, Plans are now in place for members of working groups in OGF Security and Infrastructure (networking) areas to meet at the same location and venue immediately following the Terena Networking Conference (TNC2013) in Maastricht in June. As you know from previous messages, we are referring to this activity as OGF 38a and this is a target of opportunity, as many of the relevant working group members will be there already for the TNC2013 events. Planning is now underway for the next (and main) portion of the OGF 38 activities, which involve working group sessions, BOFs, and associated OGF sessions at the XSEDE 13 conference, July 22-25, 2013, in San Diego, California. The OGF38b program committee seeks active participation from the community, and encourages the submission of session proposals that may include (but are not limited to) the following topics: * Interop/ plugfest sessions * Federated Identity and Delegation * Data/Storage * Identity Management and Virtual Organizations * Production Infrastructure Interoperability * Software Sustainability for Grids and Clouds * Green IT, Energy Efficiency * Inter-cloud interoperability and SLA management * Networking for Distributed Computing Infrastructures * Performance measurement of Grids and Clouds * Science Clouds at large scales * Grid and Cloud Security * Distributed Desktop Grid and Volunteer Computing * Emerging Distributed Infrastructure * Campus Grids and Clouds * Data Management in Grids and Clouds * Federated Infrastrucutre * OGF Chartered Group Sessions * Birds of a Feather (BoF) Sessions OGF 38b will be held in conjunction with XSEDE 13, July 22-25, 2013, in San Diego, California. There will be no separate charge or registration for OGF. OGF is currently slated to have a single track of rooms, and we will organize session requests to make best use of this track. If necessary, we can pursue additional rooms, but would first like to see the expected turnout and utilization for the space we have reserved. Please get your requests in as soon as is reasonable so that we can determine if more than one track is needed. Please select the most appropriate session type for your proposal, whether it is a "Workshop", "Presentation", "OGF Chartered Group", "OGF Birds of a Feather" or "OGF Area Meeting". The link to the call for session requests response is on the page linked below. Please contact us at events@ogf.org<mailto:events@ogf.org> if you have any questions. http://www.ogf.org/dokuwiki/doku.php/events/ogf-38b/call_for_session_proposa...
