Thursday: https://indico.egi.eu/indico/conferenceTimeTable.py?confId=2452#20150521 Friday: https://indico.egi.eu/indico/conferenceTimeTable.py?confId=2452#20150522 Opportunities will be given during the Cloud Plugfest for remote participation and an invitation is hereby extended to the community to provide and to share access to testbeds that are suited for use in this part of the program. (Please note that this will be the 16th event in this long-running testing series, and that opportunities will exist to continue the testbed work on a long-running basis as a further outgrowth of this program.) Please enjoy the rest of the EGI conference if you are attending, and we look forward to seeing you at the OGF sessions. If you are remote, please feel free to contact me regarding Cloud Plugfest remote participation details, which will also be posted to the cloudplugfest.org<http://cloudplugfest.org> and ogf.org<http://ogf.org> web sites. If you have resources that can be shared or made available for testing, please also feel free to send the info. As in previous Cloud Plugfests, a spreadsheet of available testing instances will be made available to all participants. Alan Sill VP of Standards Open Grid Forum
