Cerfacs Enter the world of high performance ...

Sparse Days Meeting 2010

Sparse Days Meeting 2010 at CERFACS
June 15th-17th,  2010


The Sparse Days this year will be combined with the final meeting of the ANR Solstice Programme. The main themes for this project were: direct methods, hybrid methods, partitioning and ordering, and web access to codes and matrices (GRID-TLSE). Thus we will make these the very non-restrictive theme for our 2010 Sparse Days meeting. The meeting will start on the morning of Tuesday June 15th and finish around midday on Thursday June 17th; the exact schedule will depend on the papers accepted for presentation.

One Cerfacs’ proposal accepted in PRACE 15th call

superadmin |  4 December 2017

This study focuses on Hall-effect thrusters, which were first invented in the 1960s. Although such systems have been extensively studied, the detailed physics of the magnetized plasmas in these thrusters is very complex and several plasma processes that have direct influence on the thruster...Read more
