2021 HPC School Application Form Registration is open till July 1st


2021 HPC SCHOOL


The strategic project "Modelling & Simulation" organizes the third school of high-performance computing (HPC).

The school is structured to be followed entirely, but also in single days, based on the level of competence and initial knowledge, as well as specific interests.

The first day, accessible also to those with limited computer and computation skills, is dedicated to some basic tools, such as Python for scientific programming, Git for version control, Bash and Make for the automation of scientific workflows. In addition to being functional to the rest of the school, this day offers a good first contact with the HPC.

The second day will cover the use of the university's HPC cluster. The fundamental objective is to provide participants with the necessary knowledge for the preparation and submission of jobs, making the most of the potential of the cluster. Particular attention will be paid to the practical rules that help improve performance, which is why a broad participation of both students and grant holders, and University staff is encouraged.

The third day will focus on parallel computing with MPI. The fundamental concepts of parallel programming will be introduced, with particular reference to the solution of partial differential equations (PDE). In particular, examples of parallelization of methods to implicit and explicit finite volumes will be proposed, with applications to the mechanics of fluids and solids.

The last two days are dedicated to Molecular Dynamics (MD) and simulations with Lammps, starting with basic elements and simple simulations, and continuing with in-depth studies both on research topics, such as active and topological polymeric systems, and on the automated management of multiple parallel simulations to explore parameter spaces.


The preliminary program only summarizes the titles and topics of the different days. In the second circular, to be distributed at the beginning of June, information on the registration and the final program will be available, with more details on the planned activities.

The school, which includes both lectures and practical "hands-on" sessions, will be held in Mesiano, in the presence, with 30 participants. Other participants will be allowed to follow in streaming. In the first two days, given the themes of widespread interest, a dozen participants may be admitted over the set limit.


Organizing committee: Marianne Corvellec, Laura Del Rio, Michael Dumbser, Luca Tubiana, Raffaello Potestio, Binayak Mukherjee, Sergio Setti & Paolo Scardi
