C fName (string) :: base name for file to read |
27 |
|
|
C filePrec (integer) :: number of bits per word in file (32 or 64) |
28 |
|
|
C arrType (char(2)) :: type of array "arr": either "RS" or "RL" |
29 |
|
|
C nNz (integer) :: size of third dimension: normally either 1 or Nr |
30 |
|
|
C arr (RS/RL) :: array to read into, arr(:,:,nNz,:,:) |
31 |
|
|
C irecord (integer) :: record number to read |
32 |
|
|
C myThid (integer) :: thread identifier |

C |
34 |
|
|
C MDSREADFIELD first checks to see if the file "fName" exists, then |
35 |
|
|
C if the file "fName.data" exists and finally the tiled files of the |
36 |
|
|
C form "fName.xxx.yyy.data" exist. Currently, the meta-files are not |
37 |
|
|
C read because it is difficult to parse files in fortran. |
38 |
|
|
C The precision of the file is decsribed by filePrec, set either |
39 |
|
|
C to floatPrec32 or floatPrec64. The precision or declaration of |
40 |
|
|
C the array argument must be consistently described by the char*(2) |
41 |
|
|
C string arrType, either "RS" or "RL". nNz allows for both 2-D and |
42 |
|
|
C 3-D arrays to be handled. nNz=1 implies a 2-D model field and |
43 |
|
|
C nNz=Nr implies a 3-D model field. irecord is the record number |
44 |
|
|
C to be read and must be >= 1. The file data is stored in |
45 |
|
|
C arr *but* the overlaps are *not* updated. ie. An exchange must |
46 |
|
|
C be called. This is because the routine is sometimes called from |
47 |
|
|
C within a MASTER_THID region. |

C |
441 |
|
|
C MDSWRITEFIELD creates either a file of the form "fName.data" and |
442 |
|
|
C "fName.meta" if the logical flag "globalFile" is set true. Otherwise |
443 |
|
|
C it creates MDS tiled files of the form "fName.xxx.yyy.data" and |
444 |
|
|
C "fName.xxx.yyy.meta". A meta-file is always created. |
445 |
|
|
C Currently, the meta-files are not read because it is difficult |
446 |
|
|
C to parse files in fortran. We should read meta information before |
447 |
|
|
C adding records to an existing multi-record file. |
448 |
|
|
C The precision of the file is decsribed by filePrec, set either |
449 |
|
|
C to floatPrec32 or floatPrec64. The precision or declaration of |
450 |
|
|
C the array argument must be consistently described by the char*(2) |
451 |
|
|
C string arrType, either "RS" or "RL". nNz allows for both 2-D and |
452 |
|
|
C 3-D arrays to be handled. nNz=1 implies a 2-D model field and |
453 |
|
|
C nNz=Nr implies a 3-D model field. irecord is the record number |
454 |
|
|
C to be read and must be >= 1. NOTE: It is currently assumed that |
455 |
|
|
C the highest record number in the file was the last record written. |
456 |
|
|
C Nor is there a consistency check between the routine arguments and file. |
457 |
|
|
C ie. if your write record 2 after record 4 the meta information |
458 |
|
|
C will record the number of records to be 2. This, again, is because |
459 |
|
|
C we have read the meta information. To be fixed. |

C |
820 |
|
|
C MDSREADFIELD first checks to see if the file "fName" exists, then |
821 |
|
|
C if the file "fName.data" exists and finally the tiled files of the |
822 |
|
|
C form "fName.xxx.yyy.data" exist. Currently, the meta-files are not |
823 |
|
|
C read because it is difficult to parse files in fortran. |
824 |
|
|
C The precision of the file is decsribed by filePrec, set either |
825 |
|
|
C to floatPrec32 or floatPrec64. The precision or declaration of |
826 |
|
|
C the array argument must be consistently described by the char*(2) |
827 |
|
|
C string arrType, either "RS" or "RL". nNz allows for both 2-D and |
828 |
|
|
C 3-D arrays to be handled. nNz=1 implies a 2-D model field and |
829 |
|
|
C nNz=Nr implies a 3-D model field. irecord is the record number |
830 |
|
|
C to be read and must be >= 1. The file data is stored in |
831 |
|
|
C arr *but* the overlaps are *not* updated. ie. An exchange must |
832 |

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

C "fName.meta" if the logical flag "globalFile" is set true. Otherwise |
1230 |

C it creates MDS tiled files of the form "fName.xxx.yyy.data" and |
1231 |
|
|
C "fName.xxx.yyy.meta". A meta-file is always created. |
1232 |
|
|
C Currently, the meta-files are not read because it is difficult |
1233 |
|
|
C to parse files in fortran. We should read meta information before |
1234 |
|
|
C adding records to an existing multi-record file. |
1235 |
|
|
C The precision of the file is decsribed by filePrec, set either |
1236 |
|
|
C to floatPrec32 or floatPrec64. The precision or declaration of |
1237 |
|
|
C the array argument must be consistently described by the char*(2) |
1238 |
|
|
C string arrType, either "RS" or "RL". nNz allows for both 2-D and |
1239 |
|
|
C 3-D arrays to be handled. nNz=1 implies a 2-D model field and |
1240 |
|
|
C nNz=Nr implies a 3-D model field. irecord is the record number |
1241 |
|
|
C to be read and must be >= 1. NOTE: It is currently assumed that |
1242 |
|
|
C the highest record number in the file was the last record written. |
1243 |
|
|
C Nor is there a consistency check between the routine arguments and file. |
1244 |
|
|
C ie. if your write record 2 after record 4 the meta information |
1245 |
|
|
C will record the number of records to be 2. This, again, is because |
1246 |
|
|
C we have read the meta information. To be fixed. |
