Call for participation for the

6th Workshop on Parallel-in-Time methods
in Monte Verità, Switzerland

23.10.2017 - 27.10.2017

The efficient use of modern high performance computing (HPC) systems has become one of the key challenges in computational science. Top HPC architectures have already attained million-way concurrency, and current trends suggest that processor counts will continue to grow rapidly. Exploiting these levels of parallelism using traditional techniques for spatial parallelism becomes problematic when, for example, the problem size per processor shrinks and communication costs begin to dominate.

For the numerical solution of time-dependent differential equations, time-parallel methods have recently been shown to provide a promising way to extend prevailing strong-scaling limits. To overcome the seemingly inherent serial dependence in the time direction, and to enable integration of multiple time-steps simultaneously, one idea of time-parallel methods is to introduce a space/time hierarchy, where integrators with different accuracies and costs are coupled in an iterative fashion. Serial dependencies are shifted to the coarsest level, allowing the computationally expensive parts on finer levels to be treated in parallel. Thus, the key to optimal parallel performance in most time-parallel methods is a well-balanced relationship between aggressive coarsening and fast convergence.

The 6th time-parallel workshop will take place in the Italian speaking part of Switzerland. Conference fee is CHF 500, which includes accommodation and all meals as well as a nice tour through the city of Bellinzona. Travel support for PhD students is available.

Deadline for submission of abstracts is
September 30, 2017. Earlier submission is welcome.

Please submit your abstract (at most one page, including references)
as a pdf to rolf.krause AT usi DOT ch

Acceptance of abstracts will be communicated individually latest within two weeks after submission.
After acceptance, rooms can be booked at the Hotel and Conference Center Monte Verità, the venue of choice of Congressi Stefano Franscini (ETHZ) subsidized conferences.

If you would like to participate without giving a presentation, you can register via email. Please be advised that in case of too many applicants, priority will be given to applicants who submit an abstract.
