Vishkin, UziDesigning a coherent agenda for the implementation of the High Performance Computing (HPC) program is a nontrivial technical challenge. Many computer science and engineering researchers in the area of HPC, who are affiliated with U.S. institutions, have been invited to contribute their agendas. We have made a considerable effort to give many in that research community the opportunity to write a position paper. This explains why we view the project as placing a mirror in front of the community, and hope that the mirror indeed reflects many of the opinions on the topic. The current paper is an organizer's summary and represents his reading of the position papers. This summary is his sole responsibility. It is respectfully submitted to the NSF.
