[ferret_users] Memory question
Hi all,
I am trying to regrid a 0.5 deg dataset to 5-min and then write it
out as a NetCDF file. I use the following commands:
use 030410_init_wsoi.nc
use vegtype_5min.nc
show grid vegtype[d=2]
show grid wsoi_lay[d=1]
define grid/X=GJR1/Y=GJR1/Z=GOL1/L=GOL1 veg_grid
let wsoi = wsoi_lay[d=1,G=veg_grid]
set variable/title="Soil Moisture" wsoi
set region/X=-179.96:179.96/Y=-89.958:89.958N/Z=0.1:4/T=6941:7275
save/file=wsoi.nc wsoi
At that point I get:
**ERROR: insufficient memory: 18662400 words were requested.
*** NOTE: You can use SET MEMORY/SIZE=xxx to increase memory.
*** NOTE: The "Memory use" section of the FERRET Users Guide has
further tips.
So I:
set memory/size=20000000
And I get:
*** NOTE: internal overflow expressing =20000000 Mwords as words.
Restoring previous memory size.
Cached data cleared from memory
If I try to set memory/size=1000000000 FERRET says it has done it,
but then I run out of memory again if I try to write out:
**ERROR: insufficient memory: 671846400 words were requested.
*** NOTE: You can use SET MEMORY/SIZE=xxx to increase memory.
*** NOTE: The "Memory use" section of the FERRET Users Guide has
further tips
Any thoughts on what is going on or how I may be able to do this?
Thank you in advance for the assistance.
Best,
Jonathan
