Patches
Download and untar these tar files in the same directory as ccsm2.0. These patches correct minor bugs in the release code, and some do change the answers slightly compared to the B20.007 control run.
- Patch 1 download. This is a bug fix in the ocean model to correct hmix_gm.F.
- Patch 2 download. This is a bug fix in the coupler to correct a very minor error in communication of the ocean tilt fields to the ice model.
- Patch 3 download intentionally left blank.
- This fixes exact restart problems on seaborg related to the massv library that was used previously. It also updates to scripts and build for bluesky. Also, the compiler defaults for IBM machines (in Macros.AIX) has be changed from O3 to O2 due to problems in new IBM compilers. Performance is literally unchanged due to the O2 degradation in compiler optimization.
