Workshop “Parallel-in-Time Integration Schemes”, June 3rd

Monday, April 4th, 2011

We would like to inform you about the following event, that the Institute of Computational Science at USI Lugano organizes in the course
of the HP2C initiative.

Workshop “Parallel-in-Time Integration Schemes”, June 3rd at the Institute of Computational Science, USI Lugano

With high performance computing systems featuring growing number of nodes, efficient strategies to parallelize all parts of a program become increasingly important. While parallelization in space by domain decomposition is already widely used, for a fixed spatial resolution this approach scales well only up to some critical number of processors beyond which the sub-domains are too small and communication becomes the bottleneck. Parallel-in-time Integration schemes provide an additional direction of parallelization, potentially allowing to reduce total execution time of parallel programs below the point where a pure spatial parallelization saturates. One algorithm from this field that received a lot of attention over the past years is “Parareal”, which has been successfully applied to a broad range of problems. The workshop is dedicated to the presentation of recent developments, advances and applications of “Parareal”.

The workshop will host four talks. We are happy to announce that three speakers have already confirmed their participation:

Prof. Martin Gander,     University of Geneva
Prof. Michael Minion,   University of North Carolina
Julien Cortial,                Stanford University

Registration for the workshop is already open »

The workshop is free of charge. Please note that the days before, the workshop “Advances in Computational Science” is also taking place at USI Lugano.

Groundbreaking method for computer simulation: Car-Parrinello method turns 25

Thursday, October 21st, 2010

ETH Life just published an article on the Car-Parrinello method for  performing ab-initio quantum mechanical molecular dynamics (MD). Prof. Parrinello, one of the two scientists that created the methods holds a dual professorship at ETH Zurich and the Università della Svizzera italiana in Lugano from 2011.

The method has been developed 25 years ago and allowed the first quantum mechanical calculation of the molecular state – “ab initio”. The Car-Parrinello method has been developed and honed for different applications over the years and has produced a lot of important information in various research disciplines.

New Institute of Computational Sciences at Università delle Svizzera italiana

Friday, October 1st, 2010

On September 20th, the Università della Svizzera italiana (USI) inaugured the new Institute of Computational Sciences (Istituto di scienze computazionali, ICS). The ICS provides a unique research environment, where strong competences in modeling, simulation and information science come together in an open and application oriented atmosphere. This “virtual laboratory” will conduct complex simulations with supercomputers and cooperate closely with the Swiss Center for Scientific Computing (CSCS) at the ETH Zurich.

ICS has been presented by the presitend of USI Piero Martinoli, the dean of the information science faculty prof. Mauro Pezzè, the director of the ICS prof. Rolf Krause,  prof. Michele Parrinello (USI and ETH Zurich) and the director of CSCS prof. Thomas Schulthess. They presented the reasons for the creation of the new institute and his potential for science, society and economy.
