15. 22.-24.09.20046th General COSMO Meeting --- Milano, Italy15 β-Version Software: INT2LM Common interpolation program INT2LM is available!!! Including GME2LM, IFS2LM, LM2LM Version int2lm_test_1.1 is under testing Implementation in Version Control System as soon as possible INT2LM shall replace GME2LM

16. 22.-24.09.20046th General COSMO Meeting --- Milano, Italy16 β-Version Software: Nesting Version More problems could be solved in the last year –Single processor runs –Treatment of external parameters for the nest –Updated nesting version to (actual) LM Version 3.9 Remaining problems –Definition and parallelization of nests (detected reproducibility problem) –relaxation of boundary and external data into the nests

17. 22.-24.09.20046th General COSMO Meeting --- Milano, Italy17 β-Version Software: Nesting Version My problem: –I did not get too much feedback on the last work! –Is there still an interest? Your problem: –Solving the remaining problems still will take some time and an experienced (parallel) programmer.

18. 22.-24.09.20046th General COSMO Meeting --- Milano, Italy18 Documentations on the Web Operational Applications (Updated!) Research Applications (Nothing available) Planned Extensions: –Update histories of the programs –History of operational versions –Description of the Working Groups This all has to be updated regularly!!!
