[MITgcm-devel] mnc pickup

[Baylor Fox-Kemper]

Hello,
   I am in agreement with Martin.  There is something screwy with the 
mnc pickups currently.  They seem to be getting written correctly, but 
not read correctly.
   I have previously suggested to Ed that mnc pickup reads be added to 
the standard platform testing package.  This serves as an official 
reminder.
   My error with mnc pickups (I'm at the head of CVS tree) is :

NetCDF ERROR:  NC_UNLIMITED size already in use
MNC ERROR: MNC_DIM_INIT ERROR: cannot create dim 'T' in file 'pickup...'

When I ncdump the pickup, it already has a 'T' in it...

Cheers,
    -Baylor


Hi,

I am trying to pickup from netcdf files on 12 CPUs, so I copy all
pickup files into my working directory (and RENAME them from
pickup.iterationnumber.0000.processorid.nc to
pickup.iterationnumber.processorid.nc, why is this necessary?) and
start from there, but I get the following error message:
 > (PID.TID 0000.0001) *** ERROR *** MNC ERROR: dimension 'Zp1' does not
 > exist for
 > file 'pickup.0000072000.000001.nc'
That's clearly true:
 > model::test> ncdump -h pickup.0000072000.000001.nc | head
 > netcdf pickup.0000072000.0000.000001 {
 > dimensions:
 >         T = UNLIMITED ; // (1 currently)
 >         Xp1 = 31 ;
 >         Y = 40 ;
 >         Z = 23 ;
 >         X = 30 ;
 >         Yp1 = 41 ;
 > variables:
 >         int iter(T) ;

my data.mnc looks like this:
 >  &MNC_01
 >  mnc_use_outdir=.TRUE.,
 >  mnc_outdir_str='mnc_',
 >  snapshot_mnc=.true.,
 >  timeave_mnc=.true.,
 >  pickup_write_mnc=.TRUE.,
 >  pickup_read_mnc=.TRUE.,
 >  &

I am using checkpoint57 for this experiment. I am NOT using the
diagnostics package. Any idea what I may be doing wrong?
