The HPC Appointment

A series of weekly meetings on High Performance Computing

ICTS is organizing a series of weekly meetings with focus on High Performance Computing (HPC) and parallel programming. The idea is to combine basic topics and their possible applications in the main scientific areas of interest for the ICTP Community.

Alternating, HPC specialists from the ICT Section will present one or more topics within a self-contained one-hour lecture. Therefore, people interested in one argument, can participate in the specific lecture without the necessity to follow the whole program.

The sessions will be organized every Tuesday from 11:00 to 12:15 starting on October 9, 2012 until the end of this year. Exceptions will be:

-  Wednesday November 14, 2012   10:00AM - 11:15 at Leonardo Da Vinci Building, Stasi Seminar Room

-  Wednesday November 21, 2012   10:00AM - 11:15 at Leonardo Da Vinci Building, Stasi Seminar Room

Below you can find the complete scheduled program. The page will further be upgraded as needed. Lecture slides will also be by time to time uploaded and made available for download. Schedule and lecture rooms might change too.

This web page along with both the science-ts@lists.ictp.it and the allusers@lists.ictp.it mailing-lists are the networks where news will get around among. Stay tuned!
