HPC Fundamentals Classes: Week 7

The Oak Ridge Leadership Computing Facility (OLCF) and National Institute for Computational Sciences (NICS) will be offering a summer training course on high-performance computing fundamentals. The course will meet once a week for 1-2 hours for eight weeks during the summer. The course is designed for summer students and interns who have no prior experience in high-performance computing topics. The course would also be beneficial for any staff wishing to learn more about high performance computing.

COURSE INTRODUCTION

The goal of this course is to provide a survey of high performance computing. The course will discuss topics related to accessing high performance computing resources, developing applications for those resources, and executing developed applications. The lectures and presentations are designed to provide knowledge and experiences to students that serve as a foundation for continued learning of high performance computing.

Who may attend: The course is limited to individuals who already have access to the ORNL campus. The course will also be webcast if there is sufficient interest.

When: Course will meet from 3:00 p.m. – 4:00 p.m. every Monday.  The classes will be held in 5100, Room 128 (Lecture Hall).

REGISTRATION IS REQUIRED

The course is designed to provide a survey of high performance computing. The focus of the course is to provide students with an introduction to the concepts, tools, and methods for using high performance computers.
