Last change on this file since 5022 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

2MODULE oasis
3!
4! This module contains subroutines for initialization, sending and receiving
5! towards the coupler OASIS3. It also contains some parameters for the coupling.
6!
7! This module should always be compiled. With the coupler OASIS3 available the cpp key
8! CPP_COUPLE should be set and the entier of this file will then be compiled.
9! In a forced mode CPP_COUPLE should not be defined and the compilation ends before
10! the CONTAINS, without compiling the subroutines.
