- 21 3-D OpenIFS forecast-only tests with and without chemistry
- 1 SCM test (based on TWP-ICE)
-j
allows the user to define the number of threads used to create and build openifs, e.g.
Code Block | ||||
---|---|---|---|---|
| ||||
$OIFS_TEST/openifs-test.sh -cbt -j 16 |
which will perform the create and build step using 16 threads
- If
-j
is not supplied as a command line argument, as in the above argument, the number of threads will default to the IFS build options for 48r1, i.e.- 64 threads for ATOS
- 8 threads for all other systems
- If
-j
argument is present, then the command line number of threads takes precedence over the defaults for any system- The default of 8 threads can be increased for larger systems. Such an increase may speed up the build. For advice on this please liaise with the system administrator.
- It is important to note that 8 threads can be problematic for older and lower spec systems. For example, it will not work with a 4 core intel m3. In this case reduce the number of threads to 2 for example.
