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 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. |

747 |
C |
748 |
C fName string base name for file to read |
749 |
C filePrec integer number of bits per word in file (32 or 64) |
750 |
C arrType char(2) declaration of "arr": either "RS" or "RL" |
751 |
C nNz integer size of third dimension: normally either 1 or Nr |
752 |
C arr RS/RL array to read into, arr(:,:,nNz,:,:) |
753 |
C irecord integer record number to read |
754 |
C myThid integer thread identifier |
755 |
C |
756 |
C MDSREADFIELD first checks to see if the file "fName" exists, then |
757 |
C if the file "fName.data" exists and finally the tiled files of the |
758 |
C form "fName.xxx.yyy.data" exist. Currently, the meta-files are not |
759 |
C read because it is difficult to parse files in fortran. |
760 |
C The precision of the file is decsribed by filePrec, set either |
761 |
C to floatPrec32 or floatPrec64. The precision or declaration of |
762 |
C the array argument must be consistently described by the char*(2) |
763 |
C string arrType, either "RS" or "RL". nNz allows for both 2-D and |
764 |
C 3-D arrays to be handled. nNz=1 implies a 2-D model field and |
765 |
C nNz=Nr implies a 3-D model field. irecord is the record number |
766 |
C to be read and must be >= 1. The file data is stored in |
767 |
C arr *but* the overlaps are *not* updated. ie. An exchange must |
768 |
C be called. This is because the routine is sometimes called from |
769 |
C within a MASTER_THID region. |

C |
1123 |
C fName string base name for file to written |
1124 |
C filePrec integer number of bits per word in file (32 or 64) |
1125 |
C arrType char(2) declaration of "arr": either "RS" or "RL" |
1126 |
C nNz integer size of third dimension: normally either 1 or Nr |
1127 |
C arr RS/RL array to write, arr(:,:,nNz,:,:) |
1128 |
C irecord integer record number to read |
1129 |
C myIter integer time step number |
1130 |
C myThid integer thread identifier |
1131 |
C |
1132 |
C MDSWRITEFIELD creates either a file of the form "fName.data" and |
1133 |
C "fName.meta" if the logical flag "globalFile" is set true. Otherwise |
1134 |
C it creates MDS tiled files of the form "fName.xxx.yyy.data" and |
1135 |
C "fName.xxx.yyy.meta". A meta-file is always created. |
1136 |
C Currently, the meta-files are not read because it is difficult |
1137 |
C to parse files in fortran. We should read meta information before |
1138 |
C adding records to an existing multi-record file. |
1139 |
C The precision of the file is decsribed by filePrec, set either |
1140 |
C to floatPrec32 or floatPrec64. The precision or declaration of |
1141 |
C the array argument must be consistently described by the char*(2) |
1142 |
C string arrType, either "RS" or "RL". nNz allows for both 2-D and |
1143 |
C 3-D arrays to be handled. nNz=1 implies a 2-D model field and |
1144 |
C nNz=Nr implies a 3-D model field. irecord is the record number |
1145 |
C to be read and must be >= 1. NOTE: It is currently assumed that |
1146 |
C the highest record number in the file was the last record written. |
1147 |
C Nor is there a consistency check between the routine arguments and file. |
1148 |
C ie. if your write record 2 after record 4 the meta information |
1149 |
C will record the number of records to be 2. This, again, is because |
1150 |
C we have read the meta information. To be fixed. |
