| 165 | | === Periodic start dates === |
| 166 | | |
| 167 | | In [#Ensemble.card ensemble.card], it is possible to specify a periodic list of start dates. Restart files will be generated for each member at each date starting from `BEGIN_INIT` to `END_INIT` with a periodicity of `PERIODICITY`, using `BEGIN_RESTART` as first restart. Leave all ''NON_PERIODIC'' options empty (`NONPERIODIC`, `RESTART_NONPERIODIC`, `INITFROM_NONPERIODIC`, `LENGTH_NONPERIODIC`).[[BR]] |
| 168 | | |
| 169 | | The following part of [#Ensemble.card ensemble.card] sets 10 years simulations from 1990-01-01 to 2000-01-01 every 2 years each with a restarts starting from 1814-12-31 every 2 years: |
| 170 | | |
| 171 | | {{{ |
| 172 | | # start date of the first periodic simulation |
| 173 | | BEGIN_INIT=19900101 |
| 174 | | |
| 175 | | # start date of the last periodic simulation |
| 176 | | END_INIT=20000101 |
| 177 | | |
| 178 | | # duration between the start of 2 periodic simulations |
| 179 | | PERIODICITY=2Y |
| 180 | | |
| 181 | | # date for the first restart (next = first+periodicity). CAUTION of the calendar (use config.card one)! |
| 182 | | BEGIN_RESTART=18141231 |
| 183 | | }}} |
| 184 | | |
| 185 | | This will produce simulations starting at the dates : 1990-01-01, 1992-01-01, 1994-01-01, 1996-01-01, 1998-01-01, 2000-01-01. (`PERIODICITY` can be given in months for shorter periods).[[BR]] |
| 186 | | |
| 187 | | The restart files are taken from `BEGIN_RESTART` every `PERIODICITY` step : 1814-12-31, 1816-12-31, 1818-12-31, etc...[[BR]] |
| 188 | | |
| 189 | | The directory in which the start date is retrieved is given by `INITPATH` and `INITFROM`.[[BR]] |
| 190 | | |
| 191 | | To restart from experiment ''v3.historical6'' in directory ''/ccc/store/cont003/dsm/p86denv/dmf_import/IGCM_OUT/IPSLCM5A/PROD/historical'' fill: |
| 192 | | |
| 193 | | {{{ |
| 194 | | # Restart name |
| 195 | | INITFROM= v3.historical6 |
| 196 | | |
| 197 | | # Restart directory |
| 198 | | /ccc/store/cont003/dsm/p86denv/dmf_import/IGCM_OUT/IPSLCM5A/PROD/historical |
| 199 | | }}} |
| 200 | | |
| 203 | | |
| 204 | | |
| 205 | | === Non-Periodic start dates === |
| 206 | | |
| 207 | | In [#Ensemble.card ensemble.card], it is also possible to specify manually all simulations running and restart dates, length, experiment names and directories to get restart files.[[BR]] |
| 208 | | |
| 209 | | First, you need to left empty the periodic attributes `BEGIN_INIT`, `END_INIT`, `PERIODICITY` and `BEGIN_RESTART` in [#Ensemble.card ensemble.card]. Then you can list the start date of all simulations with `NONPERIODIC` variable, all restart dates with `RESTART_NONPERIODIC` one, all experiments to get restart files in `INITFROM_NONPERIODIC`, all simulations restart path using `INITPATH_NONPERIODIC` and give the length of each simulation (`LENGTH_NONPERIODIC`).[[BR]] |
| 210 | | |
| 211 | | Here is an example of a configuration : |
| 212 | | |
| 213 | | {{{ |
| 214 | | # list of start dates for all simulations |
| 215 | | NONPERIODIC=(18150101 19910101 19990101) |
| 216 | | |
| 217 | | # list of corresponding restart dates |
| 218 | | RESTART_NONPERIODIC=(18141230 19901230 19981231) |
| 219 | | |
| 220 | | # simulation name to restart for each simulation. IF empty all simulations will use INITFROM one. |
| 221 | | INITFROM_NONPERIODIC=( v3.historical6 v3.historical6 v5.historical1) |
| 222 | | |
| 223 | | # directory of the restart for each simulation. IF empty all simulations will use INITPATH one. |
| 224 | | INITPATH_NONPERIODIC= ( path/to/1st path/to/2nd path/to/3rd ) |
| 225 | | |
| 226 | | # length of each simulation. If empty all simulations duration will be the default LENGTH option. |
| 227 | | LENGTH_NONPERIODIC=(10Y 10Y 50Y) |
| 228 | | }}} |
| 234 | | |
| 235 | | |
| 236 | | This will produce 3 simulations which starting at the dates : 1815-01-01, 1990-01-01 and 1999-01-01using respectively restarts from 1814-12-30, 1990-12-30, 1998-12-31 (note that the calendar should be different from the [#Config.card config.card] one) taking into ''v3.historical6'' experiment for the 2 firsts and from ''v5.historical1'' for the last one (`INITFROM` is ignored when `INITFROM_NONPERIODIC` is filled). Restarts will be taken respectively in the 3 directories specified with `INITPATH_NONPERIODIC` (`INITPATH` is ignored when `INITPATH_NONPERIODIC` is filled). Simulations length will be 10 years for the 2 firsts and 50 years for the last one. All restart experiments should be in the directory ''/ccc/store/cont003/dsm/p86denv/dmf_import/IGCM_OUT/IPSLCM5A/PROD/historical.''[[BR]] |
| 237 | | |
| 238 | | Notice that `INITFROM_NONPERIODIC`, `LENGTH_NONPERIODIC` and `INITPATH_NONPERIODIC` are not mandatory for non-periodic configuration. If you don’t fill one of them or all the `INITFROM` value and/or `LENGTH` value and/or `INITPATH` will be used for all simulations : |
| 239 | | |
| 240 | | {{{ |
| 241 | | # default length of the simulation for non periodic and duration for all periodic (in Year or Month) |
| 242 | | LENGTH=10Y |
| 243 | | […] |
| 244 | | |
| 245 | | # list of start dates for all simulations |
| 246 | | NONPERIODIC=(18150101 19910101 19990101) |
| 247 | | |
| 248 | | # list of corresponding restart dates |
| 249 | | RESTART_NONPERIODIC=(18141230 19901230 19901231) |
| 250 | | |
| 251 | | # simulation name to restart for each simulation. IF empty all simulations will use INITFROM one. |
| 252 | | INITFROM_NONPERIODIC= |
| 253 | | |
| 254 | | # length of each simulation. IF left empty all simulations durations will be the default LENGTH option. |
| 255 | | LENGTH_NONPERIODIC= |
| 256 | | |
| 257 | | # directory of the restart for each simulation. IF empty all simulations will use INITPATH one. |
| 258 | | INITPATH_NONPERIODIC= |
| 259 | | |
| 260 | | # Restart name |
| 261 | | INITFROM= v3.historical6 |
| 262 | | |
| 263 | | # Restart directory |
| 264 | | /ccc/store/cont003/dsm/p86denv/dmf_import/IGCM_OUT/IPSLCM5A/PROD/historical |
| 265 | | }}} |
| 266 | | |
| 267 | | This will produce 3 simulations starting at the dates : 1815-01-01, 1990-01-01 and 1999-01-01 using respectively restarts from 1814-12-30, 1990-12-30, 1990-12-31.[[BR]] |
| 268 | | All of them use ''v3.historical6'' experiment in `/ccc/store/cont003/dsm/p86denv/dmf_import/IGCM_OUT/IPSLCM5A/PROD/historical` directory to get restart files and their duration is 10 years. |
