- At the time of writing open-mpi is downloaded and built as part of the image creation. This is quite slow, so in the future we will investigate the use of a standard library
- If a fresh build is required but an image has already been built, then execute the following command, which is the same as above but with no-cache
| Code Block |
|---|
| language | bash |
|---|
| theme | Midnight |
|---|
| docker build --no-cache --tag "openifs-48r1.1" . |
- The tag name does not need to be provided but it is useful for identifying images.
|
Running OpenIFS -test using the docker image
Once a build has completed, the image can be checked by typing docker images , e.g.,
| Code Block |
|---|
| language | bash |
|---|
| theme | Midnight |
|---|
|
docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
openifs-48r1.1 latest f72ea92f010f 5 hours ago 2.15GB |
And the container can be run using the following
| Code Block |
|---|
| language | bash |
|---|
| theme | Midnight |
|---|
|
docker run -it 'openifs-48r1.1' |
This command will open an interactive session in the new container, in which the entry directory is the openifs-48r1.1 directory, e.g.
| Code Block |
|---|
| language | bash |
|---|
| theme | Midnight |
|---|
|
docker run -it 'openifs-48r1.1'
OpenIFS environment variables are:
------------------------------------------------------
OIFS_CYCLE=48r1
OIFS_DATA_DIR=/perm/openifs/oifs_data/48r1/48r1
OIFS_HOME=/home/openifs/openifs-48r1.1
OIFS_LOGFILE=/home/openifs/openifs-48r1.1/oifs_test_log.txt
openifs@d1bd89ccc47f:~/openifs-48r1.1$ ls
CHANGES COPYING NOTICE arch ifs-source oifs-config.edit_me.sh scripts
CITE LICENSE README bundle.yml ifs-test openifs-bundle |
| Note |
|---|
- In the above code block the openifs config (
oifs-config.edit_me.sh) is sourced automatically so the container has the correct environment for OpenIFS
|
Once inside the container, the openifs-test.sh script can be run, e.g.,
| Code Block |
|---|
| language | bash |
|---|
| theme | Midnight |
|---|
|
openifs@d1bd89ccc47f:~/openifs-48r1.1$ ./scripts/openifs-test.sh -cbt -s docker |
where :
-c will clean the directory (not necessary for a fresh image or new container)
-b will configure the bundle and build OpenIFS, i.e.,
- the OpenIFS double and single precision master executables (ifsMASTER.DP and ifsMASTER.SP, respectively) , which are used to run 3-D OpenIFS. The executables are located in
$OIFS_HOME/build/bin. - the double and single precision Single Column Model (SCM) executables (MASTER_scm.DP and MASTER_scm.SP, respectively), which are used to run the SCM derived from OpenIFS. The executables are located in
$OIFS_HOME/build/bin.
-t will run the ifs-test
- 21 3-D OpenIFS forecast-only tests with and without chemistry
- 1 SCM test (based on TWP-ICE)
-s docker defines the system as docker, which makes the script use the correct build commands
