The Pencil Code User Meeting is an annual meeting dedicated to the Pencil Code. The purpose of the meeting is to bring regular users and core developers together to discuss scientific and technical progress since the last meeting, to instigate collaborative projects and to allow new users to learn more about the code and to interact with other users and developers. The Pencil Code Meeting 2009 will be held August 24-28 2009 at the Max-Planck Institute for Astronomy (MPIA) in Heidelberg, Germany.

This new version contains a number of minor improvements and a few bug fixes.

September 28, 2009 - October 2, 2009, KITP, Santa Barbara, California, USA

Particle acceleration in shocks is the cornerstone of our interpretation of many nonthermal astrophysical sources. Due to the intrinsic plasma nonlinearities, the acceleration process and its associated phenomena, such as the generation of magnetic fields are notoriously difficult to unravel. However, the influx of new data and the development of new numerical and analytical tools make it an opportune time to reconsider the progress. This conference will address recent achievements and challenges in understanding nonlinear phenomena associated with astrophysical plasmas.

Prospects in Theoretical Physics 2009 (PiTP 2009) is intended for graduate students and postdoctoral fellows working in computational astrophysics. The goal is for young researchers to hone the numerical methods they employ in their own research and to learn about the techniques used in other areas of computational astrophysics. The lectures will cover numerical methods used in cosmology, general relativity, hydrodynamics and magnetohydrodynamics (both grid-based and particle-based), long-term orbit integrations, N-body dynamics (both collisionless and rigid-body), and radiation hydrodynamics, as well as computing with GPUs.
