VSC Training Course: Acting on Insight – Tips for Developing and Optimizing Scientific Applications


Today’s ever advancing technology platforms offer huge potential for completing faster and more advanced work but missing the vital warning signs of inefficient code behaviour will hinder your performance at any scale. Allinea tools are designed to help you get to the root causes of system crashes and bottlenecks quickly and in this training we will provide hands-on user advice for developing more robust code efficiently at VSC. The session will also demonstrate the use of the tools for getting the most out of the VSC cluster by easily identifying your biggest priorities for optimization across commonly occurring crash, memory and workload balance issues.
