[MITgcm-devel] seeking algo for globally unique per-tile file names

[Ed Hill]

Hi Andy & Chris,

I'm trying to come up with a simple method for generating globally
unique per-tile file names for mnc.  I understand that the "iG,jG"
method as used in mdsio is not valid for W2/exch2.  And I've noticed the
comment in pkg/exch2/W2_EXCH2_PARAMS.h that says:

C     W2 tile id variables (tile ids are no longer a function of
C     process and subgrid indicies).

But in spite of that comment, could we somehow determine global tile
indices using only the three variables: [myThid, bi, bj]?  Perhaps we
could add a common block with a myTileIDs(bi,bj) variable that gets
initialized by the wrapper at thread start-up?

Or is there a better way?

Ed
