OpenIFS will also run on MacOS X but we do not offer any support for use of the model on this operating system.

Support level 
 Good support; all test cases will be verified at each release
 

Medium support; not all test cases may be run depending on local resources. Typically this means the highest resolution cases will not be run.

 Minimal support. No equivalent system available at ECMWF. Relies on access to external systems or user tests.

Mac OS X. OpenIFS will run on Mac OS X using the gfortran/gcc compilers but we do not offer any technical support on this system.

Notes:

  1. gfortran version must be at least 4.5. OpenIFS is known not to work on gfortran versions less than this due to a bug in the gfortran compiler.
  2. 32bit is not supported or tested.
