Dear Colleagues, I'm writing to you today to ask for your assistance in a very important NSF-XSEDE effort. For those of you that do not know me, my name is David Lifka and I am the Director of the Cornell University Center for Advanced Computing and the Weill Cornell Medical College Director of Research Computing. I also serve as the coordinator for the XSEDE Architecture and Design team and it is in that capacity that I'm writing to you today. I've been asked by Dr. Barry Schneider of the National Science Foundation and Dr. John Towns, Principal Investigator for the XSEDE project, to collect information on how researchers are using Cloud resources today in order to guide us on how best to integrate Cloud resources into XSEDE in the future. NSF and XSEDE management would like to hear directly from researchers and educators on how they are using the Cloud, why they are using the Cloud, and the advantages the Cloud provides for their research. They especially want to hear from researchers who are not currently XSEDE users. We know that there are many compelling Cloud offerings (IaaS, SaaS, PaaS, etc.) and that many of you have had great success using these resources in innovative and exciting ways to forward your research. If you have had such a success, we strongly encourage you to fill out a short online Cloud Use Survey at: https://www.xsede.org/cloudsurvey Your participation will help the NSF plan for the future Cloud integration. If you have any questions, concerns or ideas, I'd be happy to speak with you. Just let me know (lifka@cac.cornell.edu) and we can schedule a call. On behalf of the NSF/XSEDE management team, thank you! Sincerely, David Lifka David A.
