4 Build

The script build.sh in the JMC Code L Baseline top-level directory creates three executables.

• ocn/src/tutorial_examples/global_ocean.128x64x15/mitgcmuv is the executable for the ocean component and is built from sources in sub-directories under ocn/src.
• atm/src/tutorial_examples/aim_5l.LatLon/mitgcmuv is the executable for the atmosphere component and is built from sources in sub-directories under atm/src.
• cpl/src/tutorial_examples/aim.5l_LatLon+global_ocean.128x64x15/mitgcmuv is the executable for the atmosphere ocean coupling component and is built from sources in sub-directories under cpl/src.

The three sets of directories ocn/src, atm/src and cpl/src are all organized using the MITgcm release1 scheme that is described at http://mitgcm.org/sealion.

4.1 System Requirements

A Fortran 90 compiler and system library and a compatible MPI library are required to compile and link this code. All routines are in Fortran except for a single timing routine that uses C. This routine requires a C compiler and a C library with the gettimeofday() function. Appropriate macros for calling a C procedure with a pointer to a 64-bit float are required and are included for most common platforms.
