RE: [ncl-talk] memory allocate problem

Hi Jerry,

Most common reason for occurring Malloc errors is the shell limits

How to set the value to the maximum are given below,
On the command line type the following:

limit datasize unlimited

(This is for C shell)

If you are using Korn Shell the command would be

 "ulimit -Sd unlimited"

Thanks

Debasish

Subject: memory allocate problem

hi

I read a daily data with 3 dimensions T1000(time , lat , lon)，the time is
from 19480101 to 20060131.

The code is below

begin

     f =
addfile("http://172.16.66.34/cgi-bin/nph-dods/data_online/........../NCEPRE-
Daily_T1000_d.nc" , "r")
     var = f->T1000
     var_new = short2flt(var)

end

When the code runs to var_new = short2flt(var)，it get the error message：

fatal：Nclmalloc Failed：[ error=12 ]：Cannot allocate memory
fatal：Could not coerce values for operation
fatal：Execute：Error occurred at or near line 1340 in file
$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl

So i make the time range shorter ：

begin

     f =
addfile("http://172.16.66.34/cgi-bin/nph-dods/data_online/........../NCEPRE-
Daily_T1000_d.nc" , "r")
     var = f->T1000(0:3650, : , :) ; the time only chose 10 years
     var_new = short2flt(var)

end

And the scripts will work complete.

But i need to read the whole data , how can i do ?
Thank you
