Goals of WP-M3
Work program
The project starts with defining the setups and the testing procedure, and improving the installation- and run-scripts for PALM-4U. Furthermore, the demonstration PC will be configured. As soon as new PALM-4U components are available, they will be passed through the testing procedure.
WP-M3.1: Definition of test- and benchmark-setups, improvement of PALM-4U installation/run scripts, setup of standard PC
The test- and benchmark setups will be developed in close coordination with all other work packages (especially WP-C and WP-D3). PALM-4U installation- and run-scripts will be developed and improved, based on existing PALM scripts. The project standard PC will be configured, which includes installation of compilers, libraries, and further tools (MPI, FFTW, netCDF4/HDF, NCL, etc.). PALM will be implemented on the standard PC and work packages will be given access to the system. A one-week seminar “Introduction to the PArallelized LES Model PALM” will be given for all project partners of module A, and interested partners of modules B/C, at project start, in order to make them familiar with the PALM-code as the basis of the new PALM-4U-code.
WP-M3.2: Installation and application of existing urban climate models
Existing urban climate models will be installed and run for the test-setups (as far as possible). A focus will be on codes currently used in Germany, like MUKLIMO_3, ASMUS, ENVIMET, etc.. Simulation results will later be used for comparison with results from PALM-4U.
WP-M3.3: Test and benchmark runs
New parts of PALM-4U code that create performance bottlenecks will be identified and scheduled for further optimization, including porting for accelerator boards (to be partly done by a sub-contract partner). Feedback will be given to work packages in order to improve the respective code. An optimized PALM-4U version will be availabe after 24 months.
WP-M3.4: Final documentation of test- / benchmark-setups including results
Besides the final documentation, first versions of test setup descriptions and results will be made available on the PALM-4U Trac server as soon as the setups have been defined.
