Exact time tbd. --- ## Session: HPC - Haarsträubend Problematische Computer Supercomputer sind auch nur wie Computer; nur grösser; und schlimmer (oder: Never underestimate the stupidity of dumb cpus in large groups) petschge und urs ranten über Supercomputer. Dienstag, 29.12.2020: 22:00h, im Seminarraum der Nerd2Nerd 2D-World (https://jitsi.rc3.world/seminarraum-e0a9f) > Hast du manchmal das Gefühl, dass dein Computer dich hasst? > Jetzt stell dir vor, du hättest 50.000 davon gleichzeitig. > > Petschge und urs benutzen beide seit vielen Jahren wissenschaftliche Supercomputer (HPC, High Performance Computing) und haben über die Jahre einige haarsträubende Geschichten angesammelt. In diesem Event ranten sie eine Stunde lang darüber. > > Seltsame Software-Setups: "Die Compute-nodes booten ohne Betriebssystem in deinen Code, führen ihn aus und crashen dann. Das ist by-Design so." > Parallele Dateisysteme: Schnell oder ohne Datenverlust? Choose one. > Kühlprobleme: "Unser Supercomputer kann nicht ohne Last arbeiten! Könnt ihr den mal über Weihnachten warm halten?" > Personalprobleme: "Das System war so teuer, wir hatten kein Geld mehr übrig um jemanden anzustellen, der es bedienen kann."
