[MITgcm-devel] netcdf on sx8

[Martin Losch]

Hi all,

I found a funny error with netcdf in my SX8 routine test: in lab_sea/run
I get this
 > cat STDERR.*
(PID.TID 0001.0001) *** ERROR *** NetCDF ERROR:les
(PID.TID 0001.0001) *** ERROR *** MNC ERROR: opening 'phiHydLow. 
0000000000.t002.nc'
 > cat STDOUT.0001
  NetCDF ERROR:

  Not enough space

  MNC ERROR: opening 'phiHydLow.0000000000.t002.nc'

and in ideal_2D_oce
 > cat STDERR.*
(PID.TID 0001.0001) *** ERROR *** NetCDF ERROR:

phiHydLow ist not part of the diagnostics out and flxDiag.* is only  
the 4th output stream in data.diagnostics? By lucky accident I found  
that the second error occurs when the model calls
> C       Update the record dimension by writing the iteration number

from diagnostics_out.F

"not enough space" cannot refer to disks-space, as I am well below my  
file number and disk-space quotas.

Any idea what could be going on? The other examples with netcdf seem  
to be doing fine (and in  our "production" runs we generally don't  
have problems with MITgcm+netcdf  ...)
