So, I tried this for several minutes. Basically, what I did was used R to simulate three billion pseudo-random realizations. Did not store the ouput or even put it on the screen. Piped it to system.time so that I did not get output at all. Anyway, the fan went on normally. It took 179 seconds. Used in R; > system.time(rnorm(3e9)) However, while writing this email in mutt (which involves some IO), the fan ended running, and the screeching is back and continues on even though the fan does not appear to be running. Many thanks and best wishes, Ranjan _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
