bands.F90 @ 1352

Last change on this file since 1352 was 1279, checked in by Laurent Fairhead, 15 years ago
Merged LMDZ4-dev branch changes r1241:1278 into the trunk Running trunk and LMDZ4-dev in LMDZOR configuration on local machine (sequential) and SX8 (4-proc) yields identical results (restart and restartphy are identical binarily) Log history from r1241 to r1278 is available by switching to source:LMDZ4/branches/LMDZ4-dev-20091210
Property svn:eol-style set to `native` Property svn:keywords set to `Author Date Id Revision`
