Dear PWSCF users, For all my jobs, the wall time is usually significantly larger than the CPU time. Especially the larger the job, the larger the difference. For example, for a large job run for a system of 824 electrons, I have
1d 15h58m CPU time, 2d 7h44m wall time I am using QE-4.1.2 and run on 40CPUs (each CPU has 3 tasks). Linux x86_64, and Intel Compiler 10.1.015. I don?t know what are the possible reasons that causes this delay. What factors I should look at to fix this problem. Thank you very much, Trinh Vo CalTech Jet Propulsion Lab -------------- next part -------------- An HTML attachment was scrubbed...
