eORCA1

Instructions to compile and run a global circulation configuration with NEMO 4.2

Important

Nemo 4.2 is incompatible with XIOS-2.5. This configuration has to be linked against Xios-trunk

Compilation of the base cofiguration

1. The eOrca1 configuration can be built starting from the shipped reference configuration ORCA2_ICE_PISCES. First, lets duplicate this configuration with the command

./makenemo -m 'local' -r ORCA2_ICE_PISCES -n 'OrcaDef1' -j 0;

where -j 0 sets the number of processors for compilation to 0: with this peculiar choice the command ./makenemo will only duplicate and rename the necessary files without compiling.

2. Modify the cpp_*.fcm: the file cfgs/OrcaDef1/cpp_OrcaDef1.fcm should contain the following line

bld::tool::fppkeys   key_si3 key_xios key_qco key_isf

3. Compile the code

./makenemo -m 'local' -r ORCA2_ICE_PISCES -n 'OrcaDef1' -j 32;
