Dear Firedrakers, Terry Haut is giving a seminar about parallel-in-time methods for solving PDEs with fast oscillatory waves (such as those used in weather forecasting and ocean modelling). The talk will concentrate on parallelisable methods for computing the action of the exponential of an anti-symmetric matrix (i.e. the matrix coming from discretising the linear wave part of a PDE), which are then used to take large stable timesteps for the coarse propagator in a parallel-in-time algorithm. Date: 12th September 2014 Time: 12 noon Location: Huxley 130 (i.e. the maths dungeons). http://www3.imperial.ac.uk/newsandeventspggrp/imperialcollege/naturalscience... cheers --cjc
