| 2 | === An Introduction to the '''PA'''rallelized '''L'''ES '''M'''odel '''PALM''' === |
| 3 | |
| 4 | Seminar to be held at the School of Architecture, the Chinese University of Hong Kong (CUHK), 9am to 5pm, 25th . 29th September 2013 |
| 5 | |
| 6 | PALM is a parallelized large-eddy simulation model, which has been continuously developed at the department of |
| 7 | meteorology and climatology, Leibniz Universität Hannover, Germany, since 1997. It is used to study micro- and |
| 8 | mesoscale turbulent boundary layer flows in the atmosphere and ocean by different groups of researchers all over |
| 9 | the world. Compared with many other LES models, PALM includes a number of advanced features like topography, |
| 10 | non-cyclic horizontal boundary conditions, an embedded Lagrangian particle model, or an interface for adding user |
| 11 | defined code. The ocean option of PALM includes salinity and the equation of state for seawater. A coupling |
| 12 | between PALM-atmosphere and PALM-ocean has recently been developed. Data output is in netCDF format. PALM |
| 13 | is optimized for high performance on all kind of state-of-the-art processor architectures and scales up to several |
| 14 | thousands of processors. It is free software and can be redistributed and/or modified under the terms of the GNU |
| 15 | General Public License (v3). Download information and a detailed online documentation are available under |
| 16 | http://palm.muk.uni-hannover.de. |

| 19 | '''Seminar contents''' |
| 20 | |
| 21 | The one week seminar gives an overview of PALM, explains the installation procedure, and demonstrates how to |
| 22 | carry out runs, either on Linux notebooks provided by the participants or on local PCs provided by CUHK. The |
| 23 | seminar starts with a general introduction to large eddy simulation, followed by a discussion of the basic set of |
| 24 | equations that are used in PALM, and the numerical methods that are implemented. After explaining the PALM |
| 25 | installation procedure, the main focus is given on how to set up PALM simulations and how to run them using the |
| 26 | ksh-shell scripts that are provided with PALM. Further attention is also given to questions like how to extend PALM |
| 27 | by user-defined code and how to debug the code. Setups for several standard applications will be explained in detail |
| 28 | (e.g. convection, flow around buildings, etc.). Beside the theoretical lessons given in the morning, there will also be |
| 29 | hands-on sessions in the afternoon, where participants carry out exercises under the guidance of the lecturers. |
| 30 | |
| 31 | '''Requirements''' |
| 32 | |
| 33 | '''Participants should have a solid background in CFD modelling, FORTRAN90/95, MPI, and !Linux/Unix.''' If |
| 34 | participants intend to use their own Linux notebooks for running PALM during the seminar, these notebooks should |
| 35 | have at least a dual-core processor. It is expected that the following software has been installed on the notebook by |
| 36 | the participants in advance: a FORTRAN90/95 compiler, an MPI library, the netCDF library (not later than version |
| 37 | 3.6.3), graphics software to display netCDF data (preferably NCL), the Korn- or bash shell (ksh, bash), as well as |
| 38 | subversion (a revision control system necessary to download the PALM code). subversion is already a part of many |
| 39 | Linux distributions (e.g. openSuSe). The lecturers will be Siegfried Raasch, and other members of the PALM group |
| 40 | from the Institute of Meteorology and Climatology, Leibniz Universität Hannover, Germany. |
| 41 | |
| 42 | '''Costs / fee''' |
| 43 | |
| 44 | The participant fee will be 300€ (or around HK$3,000). This includes tuition, seminar handouts and a welcome party. Accommodation costs, other meals, and transport costs are not included. |
| 45 | |
| 46 | '''Further information and Registration''' |
