Version: 2.7
This version has been tested on an SGI64 workstation, an SGI Challenge computer, a Fujitsu VPP700, a DEC ALPHA, and a Cray C90.
Download
You can download a 700 kb gzipped tar file containing the source code
of MICOM, the user manual, and a set of data files from here:
micom-2.7.tar.gz.
Installation
To install the package you should create a directory MICOM
and copy the downloaded file into it. After changing into the
MICOM directory you can unpack the tar file with the command
gunzip -c micom-2.7.tar.gz | tar xvf -Five subdirectories are created: bin contains some scripts and is the location where the MICOM executable is stored, config is where the configuration file of MICOM is located, data contains the climate input and output data, doc contains some documentation, and the source code is stored in source directory.
You can prepare the software package for compilation by typing the command
./configureThis command determines the location of the various commands (compiler, etc.) that are needed to build the MICOM executable. Note that this should be done on the machine on which the executable should run and only needs to be done once on every computer.
Finally, type
maketo compile the program. Upon successful completion you can find the executable micom-standard in the directory MICOM/bin.
Configuration
You can change any of the parameters of the MICOM program by editing
the configuration file standard in the directory
MICOM/config/standard or by using the
MICOM configurations database.
Note that after modifying this file you should
recompile the program in order for the modifications to take effect.
Information on the parameters is available in the postscipt document
doc/user_guide.engl.ps.
Compilation
You can compile the program by typing the following command in the
MICOM directory
makeAll object files and executables can be removed by typing
make clean
Running
You can perform a demo run of MICOM by typing the command
'make demo'. The following table provides some data
about memory usage and computing time for this demo run on several
computers. (The UNIX time and top utilities were
used for this.)
