Mission - An ins?tute run by scien?sts for scien?sts Foster the growth of advanced studies and research in physical and • mathema?cal sciences, especially in support of excellence in developing countries. Develop high-level scien?fic programmes keeping in mind the needs of • developing countries, and provide an interna?onal forum of scien?fic contact for scien?sts from all countries. Conduct research at the highest interna?onal standards and maintain a • conducive environment of scien?fic inquiry for the en?re ICTP community. Thanks to the generous funding from the Italian Government, UNESCO and the • IAEA, ICTP has been able to ini?ate and implement various schemes of support and assistance to scien?sts from developing countries.

Why use Computers in Science? • Use complex theories without a closed solu?on: solve equa?ons or problems that can only be solved numerically, i.e. by inser?ng numbers into expressions and analyzing the results • Do “impossible” experiments: study (virtual) experiments, where the boundary condi?ons are inaccessible or not controllable • Benchmark correctness of models and theories: the be*er a model/theory reproduces known experimental results, the be*er its predic?ons Ivan Giro*o - igiro*o@ictp.it La?n America Introductory School to Parallel Programming 17 Abacus Cinvestav, 12 Feb 2018 and Parallel Architecture for HPC

What is High-Performance Compu?ng (HPC)? • Not a real defini?on, depends from the prospec?ve: – HPC is when I care how fast I get an answer – HPC is when I foresee my problem to get bigger and bigger • Thus HPC can happen on: – A worksta?on, desktop, laptop, smartphone! – A supercomputer – A Linux Cluster – A grid or a cloud – Cyberinfrastructure = any combina?on of the above • HPC means also High-Produc?vity Compu?ng Ivan Giro*o - igiro*o@ictp.it La?n America Introductory School to Parallel Programming 19 Abacus Cinvestav, 12 Feb 2018 and Parallel Architecture for HPC
