The Oak Ridge Leadership Computing Facility (OLCF) will host a summit at Oak Ridge National Laboratory (ORNL).  The summit will provide a forum for current and prospective users to meet with OLCF staff and industry vendors to discuss Titan, the next-generation leadership-class computational resource, and a significant step towards exascale computing at the OLCF.  Users are encouraged to present their application plans for scaling to exascale.

Registration is required for this event. Information about travel and accommodations in the Oak Ridge area are provided below. Lunch and refreshments will be provided during the event.

Additionally, the event will be webcast. Please indicate if you intend to participate in person or via webcast on the registration form.

Overview
Summit Overview

The purpose of this summit is to bring together OLCF staff, current and prospective users, and vendors to discuss Titan and its implications to application development. The summit is intended to be an open forum to discuss techniques, strategies, concerns, and expectations. Users are encouraged to discuss their application roadmaps to help OLCF staff provide the appropriate assistance to ensure that user’s realize their research goals on Titan.

A variety of presentations from OLCF staff and vendors about lessons learned and the current state of development tools will serve as a backdrop to enhance the discussions about user applications with respect to their path towards exascale computing.
