Exploiting Modern High Performance Architectures with Barnes-Hut Tree Codes

The Institute of Computational Science is pleased to announce the workshop "Exploiting Modern High Performance Architectures with Barnes-Hut Tree Codes".

Date: Tuesday, March 20th, 2012
Place: USI Università della Svizzera italiana, room 354, Main building (Via G. Buffi 13)

Despite rapid development in supercomputer performance over the last three decades, solving the N-body problem with direct summation and O(N^2) complexity is and will be unfeasible for real-life applications.
Since hardware acceleration and/or parallelism can postpone but never remove the bottleneck implied by such an algorithmic complexity, much attention has been devoted to rapid summation techniques such as the Barnes-Hut tree code. In this workshop, we present and discuss new ideas aiming at the full exploitation of modern and upcoming high performance architectures.
