General description of package FORMS
Programming language,
error messages, screen output, etc.
Unified memory management.
History files.
Alphabetical list of input parameters of all programs.
Unified error management.
The error and warning messages are written to the output error file
of fixed name 'error.out'.
File 'error.out' is deleted by Perl script 'go.pl' before executing
the history file.
When an error or warning message is issued, the message is appended to
the error file, starting with string '##Error' or '##Warning',
respectively. Error file 'error.out' is checked for string
'##Error' before running the next program of the history file.
New in version 7.10
General description of data forms
- SEP (parameter files):
- SEP (Stanford Exploration Project) parameter files
are convenient for the specification of input parameters of programs,
and especially for the description of grid dimensions for the
gridded data (data forms GRD and MGRD).
Subroutines to read and write the SEP data are collected in file
sep.for.
- GSE (seismograms):
- GSE waveform data exchange files are one of many seismological
standards used to store and exchange seismograms, and are very
simple and readable ASCII files.
Subroutines to read and write the GSE files are collected in file
gse.for.
- GRD (GRiDded data):
- Singlevalued data on regular rectangular grids are written
gridpoint-by-gridpoint into formatted files.
N1*N2*N3 grid values are stored in the Fortran manner, i.e.
with the inner loop corresponding to N1 and outer loop
corresponding to N3.
The gridded data are sometimes repeated for N4 time snaphots.
In such a case, each new snapshot (N1*N2*N3 grid) should begin
on a new line.
The files are designed to be read by the list-directed input
(free format). The null values are generated in place of undefined
values (e.g., travel times in a free space). The null values are
treated as default values when read by list-directed input
(free format).
Example: 124 null values are written as ' 124* '.
The grid dimensions are usually assumed to be specified by
parameters N1, N2, N3, sometimes N4 (numbers of gridpoints),
D1, D2, D3, sometimes D4 (grid intervals),
O1, O2, O3, sometimes O4 (coordinates of the grid origin,
i.e., of the first gridpoint).
Subroutines
WARRAY and
WARAY
to write real-valued gridded data,
WARRAI and
WARAI
to write integer gridded data,
RARRAY and
RARAY
to read real-valued gridded data, and
RARRAI and
RARAI
to read integer gridded data, are collected in file
forms.for.
Subroutines with double R work with a single N1*N2*N3 spatial grid,
subroutines with single R work with a space-time grid (N4 spatial grids).
- MGRD (Multivalued GRiDded data):
- Multivalued data on regular rectangular grids are given
by a couple of files:
(a) Integer gridded data file (form GRD) containing for each gridpoint
the number of data values.
(b) Formatted file containing all data values at the first,
second, ..., last gridpoints.
The subroutines to write and read singlevalued gridded data GRD
may be used to write and read these files.
- Matrices and vectors:
- General matrices (GM), symmetric matrices (SM), skew matrices
and diagonal matrices (DM) are distinguished. Vectors are general
matrices with a single row or a single column, and are not
distinguished from general matrices.
Each matrix is stored in two files:
- The matrix header file is a formatted SEP-like file which
contains the parameters describing the matrix. The parameters are
as follows:
- IN='string' ... Name of the matrix data file.
- M1=integer ... Number of rows of the matrix.
- M2=integer ... Number of columns of the matrix.
- SPARSE='string' ... Identifies whether the matrix is written
as sparse matrix or not.
SPARSE=' ' means dense, not sparse matrix.
SPARSE='CSC' means that the matrix is written as sparse
matrix in the Compressed Sparse Column format.
- NELEM=integer ... Number of nonzero elements of the matrix.
Used only for sparse matrices (SPARSE differs from ' ').
- SYMMETRY='string' ... Identifies the symmetry of the matrix.
Possible values are 'diag' for diagonal matrix,
'sym' for symmetric matrix, 'skew' for skew matrix,
and ' ' for general matrix.
- FORM='string' ... Identifies the format of the matrix data
file. Possible values are 'formatted' and 'unformatted'.
- The matrix data file is a formatted or unformatted file with
the values of matrix elements.
For a symmetric matrix, just components from the first row
to the diagonal are stored for each column, i.e., M1*(M1+1)/2
matrix components are stored for symmetric M1*M1 matrix.
For a skew matrix, just components above the diagonal are stored,
M1*(M1-1)/2 matrix components are stored for skew M1*M1 matrix.
For a diagonal M1*M1 matrix, just M1 diagonal components are
stored.
The matrix data files differ for sparse and for dense
(not sparse) matrices:
- For dense, not sparse matrices, (SPARSE=' ') the values
of all matrix elements are stored component by component.
Components of the matrices are stored columnwise.
- For sparse matrices, Compressed Sparse Column (CSC) format
is used. In this format, the nonzero elements of the matrix
are stored columnwise, together with the integer values of
their row indices, and with the "pointers" dividing the stored
matrix elements into individual columns.
- The M2 integer pointers, corresponding to the matrix
columns, are stored first. The value of each pointer equals
the number of stored nonzero matrix elements from the
beginning of the matrix to the end of the corresponding
column.
- Then NELEM
pairs of integers equal to the row indices of nonzero matrix
elements and reals equal to the values of the nonzero matrix
elements are stored.
For formatted files, the pairs start on a new line of the file
after the pointers, and each line contains NUMLINM pairs.
Example of the pointers: Assume a matrix with 2 nonzero
elements in the first column, and 3 nonzero elements in the second
column. Than the first pointer is 2, the second pointer is 5,
and so on. The last pointer is NELEM.
The matrices may be stored either in the formatted files, or in
the unformatted files, depending on the value of input SEP
parameter FORMM of the programs dealing with the matrices.
Reading and writing of the unformatted files is usually much faster.
The formatted files are designed to be read by a single
list-directed input (free format). The number of components
per line is given by input SEP parameter NUMLINM, default for matrix
data files is NUMLINM=5. The different matrix components may
correspond to different quantities. The matrix components are
thus written using the 'E' Fortran format in order to preserve
the relative accuracy of all matrix components.
- LIN (LINes):
- Subroutine FORM2
of file forms.for may be
useful when writing these data.
- PTS (PoinTS):
- Subroutine FORM2
of file forms.for may be
useful when writing these data.
- FTT (Travel Times):
- Subroutine FORM2
of file forms.for may be
useful when writing these data.
Compiling and linking programs of package FORMS
All Fortran 77 source code and include files are assumed
to be located in a single directory when being compiled and linked.
The files with main programs contain, at their ends, Fortran 90
INCLUDE command for all subroutine files required. In this way,
each program may simply be compiled and linked as a single file.
All filenames are assumed to be expressed in lowercase.
Fortran 77 source code files have extension '.for'. The corresponding
files with specifications of the COMMON blocks have extension '.inc'
and are included in the Fortran 77 source code by means of Fortran 90
INCLUDE command.
Compilation and linking:
- Copy all files (or at least all *.for, *.inc
and *.pl files) of package FORMS
into your working directory.
All the files may also be extracted using
pkunzip -d forms.zip or
tar -xvf forms.tar.
At http://sw3d.cz, *.zip contain ASCII files in the DOS format.
At http://sw3d.cz, *.tar contain ASCII files in the UNIX format.
On the UNIX disk, *.zip and *.tar contain ASCII files
in the UNIX format.
On the DOS disk, *.zip and *.tar contain ASCII files
in the DOS format.
- If you wish to compile following programs
you need also few subroutines (mentioned in parentheses)
of the Numerical Recipes
and the corresponding licence.
grdfft.for
(fourn.for),
grdran2d.for
(fourn.for, ran2.for, ran3.for),
grdran.for
(ran3.for),
grdckn.for
(gammln.for, bessik.for, beschb.for, chebev.for),
smpower.for
(indexx.for, tred2.for, tqli.for, pythag.for),
smeigen.for
(indexx.for, tred2.for, tqli.for, pythag.for).
Necessary subroutine files are included at the end of above
listed files containing main programs.
- On a computer with a very small memory (less than 16 MB), you may
need to decrease array dimension MRAM in the include file
ram.inc.
You may also wish to increase array dimension MRAM in the include file
ram.inc if 16 MB are not
sufficient for your calculations.
- Edit Perl script f.pl
designed to compile and link a single file according to your
Fortran compiler and linker.
Test Perl script f.pl by entering command
perl f.pl do-test
to compile program
do-test.for,
which may be executed on most systems by entering command
do-test
- If you have no Perl interpreter, it should be available at
www.perl.org.
You may ask your system manager to install the Perl interpreter.
- Run Perl script
fforms.pl
by entering command
perl fforms.pl
to compile and link the programs of package FORMS.
For the list of files to compile and link, refer to
Perl script fforms.pl,
which employs Perl script
f.pl
to compile each program.
All necessary subroutine files and include files are included
by the Fortran 90 INCLUDE command.
Fortran 77 subroutine files are included at the end of above
listed files containing main programs.
Running programs of package FORMS
All Fortran 77 source code and include files together with all the
Perl scripts and data files of package FORMS are assumed
to be located in the same single working directory
in which the programs will be run.
It is recommended to run the programs from the
history files.
The history files may contain the information how to execute the programs,
the data read from standard input (Fortran)
or from the command line (Perl) and the data read
from the SEP parameter files.
Data from standard input *:
Main input data of each program are read from the standard input,
and mostly consist of a single line containing filenames and
at most few numerical parameters.
For the description of input data of individual programs refer to
the list of files below.
Path to the root directory of the SW3D software:
There is a possibility to edit file
go.pl
and set path to the root directory of the SW3D software in global
variable $SW3D
to enable full functionality of the Perl
script chk.pl. Some history
files will then be able to copy their input data
from the SW3D-CD disk to the working directory automatically.
