 Shortly after v5.9.0, we have successfully implemented a new mode of efficient I/O using dedicated 'scribes'. At runtime, the user needs to specify number of scribe cores (equal to # of 3D outputs variables (vectors counted as 2) plus 2), and the code, compiled without USE_OLDIO, will output combined netcdf outputs for each 3D variable and also all 2D variables in out2d*.nc. Sample 3D outputs are: salinity_*.nc, horizontalVelX_*.nc etc - note that vectors variable names end with 'X,Y'.
