Although a fix was implemented that improved the performance in idealised test cases the performance in realistic simulations (e.g. ORCA025) is worse. It is not clear that the new or old formulation is correct for the case of sloping bathymetry and partial steps. 186 187 187 [[BR]] ''' Status: ''' [[BR]] ''' Main Tasks: ''' [[BR]] ''' Science Reviewer:''' [[BR]] ''' System Reviewer:''' [[BR]] ''' Deadline:''' [[BR]] ''' Priority:''' [[BR]] ''' Depends on:'''[[BR]]188 [[BR]] ''' Status: ''' [[BR]] ''' Main Tasks: ''' [[BR]] ''' Science Reviewer:''' [[BR]] ''' System Reviewer:''' [[BR]] ''' Deadline:''' [[BR]] ''' Priority:''' [[BR]] ''' Depends on:''' [[BR]] 188 189 189 190 '''ROBUSTNESS-3 / CNRS - Academic test cases in the system''' … … 209 210 210 211 * Follow-up the status of the trusting for supported configurations & HPC centers 212 * Finalize documentation (help content, wiki page, ...) 211 213 * Complete the list of monitored configurations & add new features for improvement 212 * If needed, 214 * If needed,install the trusting on new HPCC for benchmarking the code over several centers 213 215 214 216 '''Science Reviewer:'''[[BR]]'''System Reviewer:''' [[BR]]'''Deadline:''' [[BR]]'''Priority:''' Medium[[BR]]'''Depends on:''' [[BR]]'''Principal Investigator: '''Nicolas Martin … … 226 228 227 229 ==== ROBUSTNESS-10 / CNRS - Evolution of the Collaborative Development Environment (CDE) ==== 228 '''Motivation: '''in anticipation of the web server EOL hosting the NEMO website[[BR]]'''Status: '''[[BR]]'''Main Tasks:''' 229 230 1.
