Currently I am working on a simulation project which I develop in my own pc (Chakra linux, intel core i5). When I compile using icpc v 14.0.2 I get really nice results in terms of speed. The problem is that when I compile the code in a cluster (CentOs, Xeon E7-8837 ) using icpc v 13.1.1 the execution time doubles. I have really no clue on what can be the cause of such behavior as my code is relatively simple. I would like to know what could be the possible causes and how to check them. Also If further information is needed please let me know so I can update the post.
