Description

[ONLINE] Efficient Use of HPC Systems

Description

The purpose of this course is to guide existing and potential users on how to efficiently use HPC systems, and to present typical HPC tools, the software environment, compilers, libraries, parallel environments, batch system and best practices.

The trainees will learn what the HPC systems offer, how they work, how to make efficient use of resources and how to apply for access to PRACE and similar infrastructures.

Prerequisites

The course is addressed to any potential user of an HPC infrastructure.  Background in modules, compilers, MPI/OpenMP/Cuda, batch systems and running time consuming applications, is desirable but not mandatory.

The hands-on sessions, will take place on an HPC-like environment in a VirtualBox image. Participants will be guided step by step on how to install and use the VirtualBox at the beginning of hands-on sessions.

Course language is English.

Registration

Registrations will be evaluated on a first-come, first-served basis. GRNET is responsible for the selection of the participants on the basis of the training requirements and the technical skills of the candidates. GRNET will also seek to guarantee the maximum possible geographical coverage with the participation of candidates from many countries.

The zoom room will be open about 1 hour prior to the course schedule in order for the participants to test their connection.

He has extensive HPC and grid computing experience. He is using HPC systems in computational chemistry research projects.  In EGEE/EGI projects he acted as application support and VO software manager for SEE VO, grid sites administrator (HG-02, GR-06), NGI_GRNET support staff (2008-2014). In PRACE 1-6 IP he is involved in benchmarking tasks (2010-2020). Currently he is leader of the HPC team at GRNET S.A.

Mr. Kyriakos Ginis received his Diploma in Electrical and Computer Engineering in 2003 from the National Technical University of Athens, Greece. Between 2004 and 2014 he participated in the european projects EGEE I/II/III and EGI as a grid site administrator of the HellasGrid sites HG-01-GRNET, HG-06-EKT and HG-08-Okeanos. Since 2014 he works at GRNET as a system administrator of the ARIS HPC system, primarily responsible for hardware, operating systems and file/storage systems. He continues maintaining the HellasGrid sites HG-06 and HG-08, and supports other GRNET services such as the unique and persistent identifiers (PID) service, also part of the EUDAT project.
