C The five "public" routines supplied here are: |
| 6 |
C |
| 7 |
C MDSREADFIELD - read model field from direct access global or tiled MDS file |
| 8 |
C MDSWRITEFIELD - write model field to direct access global or tiled MDS file |
| 9 |
C MDSFINDUNIT - returns an available (unused) I/O channel |
| 10 |
C MDSREADVECTOR - read vector from direct access global or tiled MDS file |
| 11 |
C MDSWRITEVECTOR - write vector to direct access global or tiled MDS file |
| 12 |
C |
| 13 |
C all other routines are "private" to these utilities and ought |
| 14 |
C not be accessed directly from the main code. |

C Created: 03/16/99 adcroft@mit.edu |
| 17 |
C Modified: 03/23/99 adcroft@mit.edu |
| 18 |
C To work with multiple records |
| 19 |
C Modified: 03/29/99 eckert@mit.edu |
| 20 |
C Added arbitrary vector capability |
| 21 |
C Modified: 07/27/99 eckert@mit.edu |
| 22 |
C Customized for state estimation (--> active_file_control.F) |
| 23 |
C this relates only to *mdsreadvector* and *mdswritevector* |
| 24 |
C Modified: 07/28/99 eckert@mit.edu |
| 25 |
C inserted calls to *print_message* and *print_error* |
| 26 |
C |
| 27 |
C To be modified to work with MITgcmuv message routines. |

C Arguments: |
| 40 |
C |
| 41 |
C fName string base name for file to read |
| 42 |
C filePrec integer number of bits per word in file (32 or 64) |
| 43 |
C arrType char(2) declaration of "arr": either "RS" or "RL" |
| 44 |
C nNz integer size of third dimension: normally either 1 or Nr |
| 45 |
C arr RS/RL array to read into, arr(:,:,nNz,:,:) |
| 46 |
C irecord integer record number to read |
| 47 |
C myThid integer thread identifier |
| 48 |
C |
| 49 |
C MDSREADFIELD first checks to see if the file "fName" exists, then |
| 50 |
C if the file "fName.data" exists and finally the tiled files of the |
| 51 |
C form "fName.xxx.yyy.data" exist. Currently, the meta-files are not |
| 52 |
C read because it is difficult to parse files in fortran. |
| 53 |
C The precision of the file is decsribed by filePrec, set either |
| 54 |
C to floatPrec32 or floatPrec64. The precision or declaration of |
| 55 |
C the array argument must be consistently described by the char*(2) |
| 56 |
C string arrType, either "RS" or "RL". nNz allows for both 2-D and |
| 57 |
C 3-D arrays to be handled. nNz=1 implies a 2-D model field and |
| 58 |
C nNz=Nr implies a 3-D model field. irecord is the record number |
| 59 |
C to be read and must be >= 1. The file data is stored in |
| 60 |
C arr *but* the overlaps are *not* updated. ie. An exchange must |
| 61 |
C be called. This is because the routine is sometimes called from |
| 62 |
C within a MASTER_THID region. |

C Arguments: |
| 416 |
C |
| 417 |
C fName string base name for file to written |
| 418 |
C filePrec integer number of bits per word in file (32 or 64) |
| 419 |
C arrType char(2) declaration of "arr": either "RS" or "RL" |
| 420 |
C nNz integer size of third dimension: normally either 1 or Nr |
| 421 |
C arr RS/RL array to write, arr(:,:,nNz,:,:) |
| 422 |
C irecord integer record number to read |
| 423 |
C myIter integer time step number |
| 424 |
C myThid integer thread identifier |
| 425 |
C |
| 426 |
C MDSWRITEFIELD creates either a file of the form "fName.data" and |
| 427 |
C "fName.meta" if the logical flag "globalFile" is set true. Otherwise |
| 428 |
C it creates MDS tiled files of the form "fName.xxx.yyy.data" and |
| 429 |
C "fName.xxx.yyy.meta". A meta-file is always created. |
| 430 |
C Currently, the meta-files are not read because it is difficult |
| 431 |
C to parse files in fortran. We should read meta information before |
| 432 |
C adding records to an existing multi-record file. |
| 433 |
C The precision of the file is decsribed by filePrec, set either |
| 434 |
C to floatPrec32 or floatPrec64. The precision or declaration of |
| 435 |
C the array argument must be consistently described by the char*(2) |
| 436 |
C string arrType, either "RS" or "RL". nNz allows for both 2-D and |
| 437 |
C 3-D arrays to be handled. nNz=1 implies a 2-D model field and |
| 438 |
C nNz=Nr implies a 3-D model field. irecord is the record number |
| 439 |
C to be read and must be >= 1. NOTE: It is currently assumed that |
| 440 |
C the highest record number in the file was the last record written. |
| 441 |
C Nor is there a consistency check between the routine arguments and file. |
| 442 |
C ie. if your write record 2 after record 4 the meta information |
| 443 |
C will record the number of records to be 2. This, again, is because |
| 444 |
C we have read the meta information. To be fixed. |

C filePrec integer number of bits per word in file (32 or 64) |

C |

C MDSREADFIELD first checks to see if the file "fName" exists, then |
| 762 |
C if the file "fName.data" exists and finally the tiled files of the |
| 763 |
C form "fName.xxx.yyy.data" exist. Currently, the meta-files are not |
| 764 |
C read because it is difficult to parse files in fortran. |
| 765 |
C The precision of the file is decsribed by filePrec, set either |
| 766 |
C to floatPrec32 or floatPrec64. The precision or declaration of |
| 767 |
C the array argument must be consistently described by the char*(2) |
| 768 |
C string arrType, either "RS" or "RL". nNz allows for both 2-D and |
| 769 |
C 3-D arrays to be handled. nNz=1 implies a 2-D model field and |
| 770 |
C nNz=Nr implies a 3-D model field. irecord is the record number |
| 771 |
C to be read and must be >= 1. The file data is stored in |
| 772 |
C arr *but* the overlaps are *not* updated. ie. An exchange must |

C be called. This is because the routine is sometimes called from |

C |

C fName string base name for file to written |
| 1131 |
C filePrec integer number of bits per word in file (32 or 64) |
| 1132 |
C arrType char(2) declaration of "arr": either "RS" or "RL" |
| 1133 |
C nNz integer size of third dimension: normally either 1 or Nr |
| 1134 |
C arr RS/RL array to write, arr(:,:,nNz,:,:) |
| 1135 |
C irecord integer record number to read |
| 1136 |
C myIter integer time step number |
| 1137 |
C myThid integer thread identifier |
| 1138 |
C |
| 1139 |
C MDSWRITEFIELD creates either a file of the form "fName.data" and |
| 1140 |
C "fName.meta" if the logical flag "globalFile" is set true. Otherwise |
| 1141 |
C it creates MDS tiled files of the form "fName.xxx.yyy.data" and |
| 1142 |
C "fName.xxx.yyy.meta". A meta-file is always created. |
| 1143 |
C Currently, the meta-files are not read because it is difficult |
| 1144 |
C to parse files in fortran. We should read meta information before |
| 1145 |
C adding records to an existing multi-record file. |
| 1146 |
C The precision of the file is decsribed by filePrec, set either |
| 1147 |
C to floatPrec32 or floatPrec64. The precision or declaration of |
| 1148 |
C the array argument must be consistently described by the char*(2) |
| 1149 |
C string arrType, either "RS" or "RL". nNz allows for both 2-D and |
| 1150 |
C 3-D arrays to be handled. nNz=1 implies a 2-D model field and |
| 1151 |
C nNz=Nr implies a 3-D model field. irecord is the record number |
| 1152 |
C to be read and must be >= 1. NOTE: It is currently assumed that |
| 1153 |
C the highest record number in the file was the last record written. |
| 1154 |
C Nor is there a consistency check between the routine arguments and file. |
| 1155 |
C ie. if your write record 2 after record 4 the meta information |
| 1156 |
C will record the number of records to be 2. This, again, is because |
| 1157 |
C we have read the meta information. To be fixed. |
