Revision 1.12 - (show annotations) (download)
Wed Dec 9 16:11:51 1998 UTC (25 years, 5 months ago) by adcroft
Branch: MAIN
CVS Tags: checkpoint19, checkpoint20, checkpoint21
Changes since 1.11: +2 -1 lines
Added IMPLICIT NONE in a lot of subroutines.
Also corrected the recip_Rhonil bug: we didn't set it in ini_parms.F

6 C /==========================================================\
7 C | SUBROUTINE DO_THE_MODEL_IO |
8 C | o Controlling routine for IO in model main time-stepping |
9 C | loop. |
10 C |==========================================================|
11 C | Many systems do not have thread safe IO so it is easier |
12 C | to lump everything together and do dumping of fields |
13 C | and updating of forcing terms in a single place. |
14 C | The approach to IO used here is that writes are only |
15 C | performed by thread 1 and that a process only writes out |
16 C | its data ( it does not know about anyone elses data!) |
17 C | Reading on the other hand is assumed to be from a file |
18 C | containing all the data for all the processes. Only the |
19 C | portion of data of interest to this process is actually |
20 C | loaded. To work well this assumes the existence of some |
21 C | reliable tool to join datasets together at the end of a |
22 C | run - see joinds.p |
