On July 26th, representatives from PGI will be here to discuss the latest version of the PGI compiler (v. 11.7). PGI has also offered to stay on for the remainder of the day and an extra day (July 27th) to be available for one-on-one code sessions to better understand the applications to see where PGI might be able to help.

There will be an approximately two-hour presentation on compilers with the remainder of the time left for one-on-one discussions.
