1 Format for raw output files from MITgcmUV
2 =========================================

4 Introduction
5 ------------
6 When running in parallel mode with multiple processes the MITgcmUV
7 model operates as N separate programs, each responsible for its "local"
8 region of the "total" model domain. Synchronisation and sharing of data between
9 these processes is done explicitly by calls to data exchange and
10 barrier routines. Consequently there is no single program that has
11 a view of the whole model domain as the code is running. Any simple
12 I/O can only operate on the local region of the model domain - I/O
13 operations to and from datasets that represent the total domain need
14 to address the multiple process behavior explicitly.
15 Under MITgcmUV there are a set of I/O support routines that mask the
16 details of this process and enable end-users to read and write datasets
17 in a straight-forward manner. The routines use the following design
18 strategy:
19 o Input datasets are for the total domain
20 o Output datasets are for the local domain
21 o A separate program "joinds" is provided which joins a set of
22 local domain datasets together to form total model domain dataset.

74 this - Thread id of the calling subroutine
75
76 Dataset format
77 --------------
78 Datasets are written using the standard Fortran 77 sequential binary
79 file format. The Fortran IO statements in he model code do not specify any
80 particular format, however, compile and run-time flags are used on some platforms.
81 On DEC platforms by default the IO form is set to big-endian with a compile time
82 flag. On CRAY platforms a runtime flag is normally used to select IEEE
83 representation. The Fortran 77 sequential binary file format is
84 4 byte header
85 data
86 4 byte terminator
87 The header and terminator are unsigned integers which give the length
88 of the data section in bytes. This is format is standard over all UNIX
89 platforms. In Fortran this style of file is generated by code of the
90 form
91
92 REAL A(dim1, dim2, ..... )
93 OPEN(unitnumber,filename,FORM='FORMATTED')
94 WRITE(unitnumber) A
95 END
96
97 The data is sequenced in the standard Fortran convention of the left-most
98 index varying fastest. This convention holds for any dimension of datsets
99 one-dimensional, two-dimensional, three-dimensional and four-dimensional or
100 more datasets are all written this way.
101
102 Multiprocess support
103 --------------------
104 The format described above is used for multi-process simulations. In this
105 case the data written to separate files with each process writing data that
106 is local to it. To support this approach a file naming convention is used and a second
107 file of "meta" information accompanines the data. The naming convention
108 is used to avoid duplicate names and to make it easy to identify sets of
109 files that together represent the total domain data. The meta file contains
110 information about the extent of the sub-domain within each file.
111 The naming convention used is
112 PREF.SUFF.pPNUMBER.tTNUMBER.data
113 PREF.SUFF.pPNUMBER.tTNUMBER.meta
114
115 where
116 PREF - Is a field identifying the data within the file. For
117 temperature PREF is T, for zonal velocity PREF is U etc...
118 SUFF - Is a field identifying the "instance" of the data within the
119 file. The instance is typically the time level. In general
120 the instance will be a model timestep number.
121 PNUMBER - Is a process number used to identitfy which process of
122 a multi-process run generated this data. The number ranges
123 from 0 to (number of processors)-1.
124 TNUMBER - Is a thread number used to identify which thread of a
125 multi-threaded run generated this data. The number ranges
126 from 0 to (number of threads)-1.
127
128 the .data suffix identifies the file containing the actual data.
129 the .meta suffix identifies the file containing textual information
130 indicating the extent of the domain written to the .data file.
131
132 .meta file Format
133 -----------------
134 This file contains a set of parameters that are specified using the
135 generic parameter specification format used in GCMPACK software. This
136 format consists of a sequence of assignments and comments
137 Assignments have the form
138 keyword =[ val-list ];
139
140 where
141 keyword is a text string
142 val-list is a sequence of one or more fields separated by commas
143
144 Comments are preceeded by // or # characters or contained in
145 /* */ pairs.
146 The keywords contained in a .meta file are
147 id - This is a numeric identifier. It can be used to
148 verify consistency over a set of .meta files.
149 nDims - This is a single integer indicating the dimensionality
150 of the data in the .data file.
151 dimList - This is a sequence of triplets. There is one triplet for
152 each dimension and the triplets are ordered in the same
153 way as the dimensions. Each triplet is made of three integers.
154 The first integer gives the domain extent globally for
155 the associated dimension.
156 The second integer gives the low coordinate for the values
157 within .data file for the associated dimension.
158 The third integer gives the high coordinate for the values
159 within .data file for the associated dimension.
160 Thus for a .data file containing the north-west quadrant of
161 a global domain of size 90 x 40 the .meta might read
162 nDims = [ 2 ];
163 dimList = [ 90, 46, 90, 40, 1, 20];
164 For a global domain of size 90 x 40 x 33 the .meta file
165 would read
166 nDims = [ 3 ];
167 dimList = [ 90, 46, 90, 40, 1, 20, 33, 1, 33];
168
169
170
171 Example matlab program to join files
172 ------------------------------------
173 The following matlab script joins together a collection of files that
174 were written in split form. The files to join are indicated by a user
175 defined PREF.SUFF pair. e.g. T.0000002800. The script uses the UNIX
176 ls command to find all files starting with T.0000002800 and then
177 scans the .meta files to extract the dimensions. It then merges all
178 the sections together to form a complete representation of the global
179 dataset.
