Port CICE to Carpenter for intel, cray, and gnu compilers with mpich. Will add weekly testing on Carpenter, Onyx was recently decommissioned.

During development

• It was discovered that the serial compilers and parallel compilers produce different results. This was reported to sys admins. Serial compilation is done with the parallel compilers to ensure bit-for-bit results with serial and mpi comm versions.
• It was discovered that the openmpi and intel mpi options are not working properly. This was reported to sys admins. All testing is done with mpich for now.
