set cachesf num
Use this command to change the scale factor for setting the default cache size (in bytes), which is calculated according to this formula:
X grid size * Ygrid size * 8 * cachesf
The default cache scale factor is 1.
This command is available with GrADS version 2.0.a8 or later.
The cache size is only relevant when reading HDF5 and NetCDF4 data types.
Cache size is set on a per-file basis; the cache size will be different for each file opened in GrADS. After a file is opened, a new cache is allocated for each variable that gets displayed in the file. Be careful
Current value of the cache size may be discovered with the query cache command.
Please see the documentation on compression for more details.
