346	Corrected parallel bugs in ana_psource.h	arango	arango	"The analytical specification of point sources ('''TS_PSOURCE''', '''UV_PSOURCE''', and '''Q_PSOURCE'''), in '''ana_psource.h''', are extremely tricky in ROMS parallel applications. This is due to ROMS coarse-grain parallel design that support serial, serial with tile partitions, parallel shared-memory ('''OpenMP'''), and parallel distributed-memory ('''MPI''').  It requires full knowledge of ROMS framework design and parallelism to modify this '''ana_psource.h'''.  So please look at the corrected routine and study it.  I highly recommend you to understand first what it is involve before attempting to modidy this routine.

The routine '''ana_psource.h''' was previously designed for serial applications without tile partitions.  The example tests cases were very simple and small and didn't required running in parallel. Nowadays, there is an increased number of users using this routine for their own applications. So I decided to correct this routine for you to have an idea of what it is involved.  Still the best way to specify the point sources (river runoff) in ROMS is from an input (river) forcing NetCDF.  Then, ROMS will take care of all the parallel issues internally."	bug	closed	major	Release ROMS/TOMS 3.3	Nonlinear	3.3	Fixed
