Registration is required. Only those who have access to the ORNL campus can attend this workshop in person. This training event will also be webcast for those who cannot attend in person. Directions for joining the webcast will be emailed separately.

Overview

On July 26th, representatives from PGI will be here to discuss the latest version of the PGI compiler (v. 11.7).
