Re: memory problem

Hi,

I have 8Gb of RAN, I


here is the PrintVarSummary information
 printVarSummary(vrt)

Variable: vrt
Type: float
Total Size: 1351142400 bytes
            337785600 values
Number of Dimensions: 3
Dimensions and sizes: [initial_time0_hours | 2920] x [g0_lat_1 | 241] x
[g0_lon_2 | 480]
Coordinates:
            initial_time0_hours: [876576..885333]
            g0_lat_1: [-90..90]
            g0_lon_2: [ 0..359.25]

Could it be because uv has more than 2Gbt ?

Variable: uv
Type: float
Total Size: 2702284800 bytes
            675571200 values
Number of Dimensions: 4
Dimensions and sizes: [2] x [2920] x [241] x [480]
