Open Lab Session:

Following the tutorial presentations, there will be an open lab session with the instructors. Bring your codes and/or example input files for domain-specific applications, for consultation on compilation, job submission, and batch submission, or to debug performance issues. If application installation is required in advance, contact help@carc.unm.edu.

Instructors:

Dr. Ryan Johnson, CARC Systems and User Services Group
Jim Prewett, CARC Systems and User Services Group
