C Arguments: |
25 |
C |
26 |
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) declaration of "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 |
33 |
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 to floatPrec32 or floatPrec64. The precision or declaration of |
437 |
C the array argument must be consistently described by the char*(2) |
438 |
C string arrType, either "RS" or "RL". nNz allows for both 2-D and |
439 |
C 3-D arrays to be handled. nNz=1 implies a 2-D model field and |
440 |
C nNz=Nr implies a 3-D model field. irecord is the record number |
441 |
C to be read and must be >= 1. NOTE: It is currently assumed that |
442 |
C the highest record number in the file was the last record written. |
443 |
C Nor is there a consistency check between the routine arguments and file. |
444 |
C ie. if your write record 2 after record 4 the meta information |
445 |
C will record the number of records to be 2. This, again, is because |
446 |
C we have read the meta information. To be fixed. |

C Arguments: |
785 |
C |
786 |
C fName string base name for file to read |
787 |
C filePrec integer number of bits per word in file (32 or 64) |
788 |
C arrType char(2) declaration of "arr": either "RS" or "RL" |
789 |
C nNz integer size of third dimension: normally either 1 or Nr |
790 |
C arr RS/RL array to read into, arr(:,:,nNz,:,:) |
791 |
C irecord integer record number to read |
792 |
C myThid integer thread identifier |
793 |
C |
794 |
C MDSREADFIELD first checks to see if the file "fName" exists, then |
795 |
C if the file "fName.data" exists and finally the tiled files of the |
796 |
C form "fName.xxx.yyy.data" exist. Currently, the meta-files are not |
797 |
C read because it is difficult to parse files in fortran. |
798 |
C The precision of the file is decsribed by filePrec, set either |
799 |
C to floatPrec32 or floatPrec64. The precision or declaration of |
800 |
C the array argument must be consistently described by the char*(2) |
801 |
C string arrType, either "RS" or "RL". nNz allows for both 2-D and |
802 |
C 3-D arrays to be handled. nNz=1 implies a 2-D model field and |
803 |
C nNz=Nr implies a 3-D model field. irecord is the record number |
804 |
C to be read and must be >= 1. The file data is stored in |
805 |
C arr *but* the overlaps are *not* updated. ie. An exchange must |
806 |
C be called. This is because the routine is sometimes called from |
807 |
C within a MASTER_THID region. |

C |
1180 |
C fName string base name for file to written |
1181 |
C filePrec integer number of bits per word in file (32 or 64) |
1182 |
C arrType char(2) declaration of "arr": either "RS" or "RL" |
1183 |
C nNz integer size of third dimension: normally either 1 or Nr |
1184 |
C arr RS/RL array to write, arr(:,:,nNz,:,:) |
1185 |
C irecord integer record number to read |
1186 |
C myIter integer time step number |
1187 |
C myThid integer thread identifier |
1188 |
C |
1189 |
C MDSWRITEFIELD creates either a file of the form "fName.data" and |
1190 |
C "fName.meta" if the logical flag "globalFile" is set true. Otherwise |
1191 |
C it creates MDS tiled files of the form "fName.xxx.yyy.data" and |
1192 |
C "fName.xxx.yyy.meta". A meta-file is always created. |
1193 |
C Currently, the meta-files are not read because it is difficult |
1194 |
C to parse files in fortran. We should read meta information before |
1195 |
C adding records to an existing multi-record file. |
1196 |
C The precision of the file is decsribed by filePrec, set either |
1197 |
C to floatPrec32 or floatPrec64. The precision or declaration of |
1198 |
C the array argument must be consistently described by the char*(2) |
1199 |
C string arrType, either "RS" or "RL". nNz allows for both 2-D and |
1200 |
C 3-D arrays to be handled. nNz=1 implies a 2-D model field and |
1201 |
C nNz=Nr implies a 3-D model field. irecord is the record number |
1202 |
C to be read and must be >= 1. NOTE: It is currently assumed that |
1203 |
C the highest record number in the file was the last record written. |
1204 |
C Nor is there a consistency check between the routine arguments and file. |
1205 |
C ie. if your write record 2 after record 4 the meta information |
1206 |
C will record the number of records to be 2. This, again, is because |
1207 |
C we have read the meta information. To be fixed. |
