We are trying to make plans for which version of cesm to use during this coming year. It would be preferable for us to continue using cesm1_2_2 until some current projects are completed. Will this version be ported to phase 2 of NERSC Cori? Or will cesm2.0 be the only supported version? Note we are more concerned about functionality than performance.Thanks, Michael

Althought the cesm1.2.2.1 release update contains a cori-knl configuration, we have not yet been able to acheive satisfactory performance on cori-knl with most cesm setups.   In particular we have not been able to successfully enable openmp threads which I understand to be crucial to performance on KNL.  We welcome input from the community if you find successful configurations for this machine.
