[ncl-talk] Dataset required

[mamadoulamine.mbaye at ucad.edu.sn]

Hi Soma
You can try this:
open any text editor and paste the content of the  ".hluresfile", and save it in your home directory with the same name. Please do not forget the dot before hluresfile. I will be a hidden file.
Hope this will help.
Best Regards,
Mamadou

Hello,
Can you inform me where to create/paste "." into the ncl package?

Can we keep it in current directory?

So your system is reporting wmMaximumSize as 100MB, which is the default, and should be more than sufficient for the dataset in question. I tried limiting my system to 100MB (I generally have it set to 500MB), and the script ran just fine.

So I'm not sure what to advise you at this point. You can try to increase the wsMaximumSize, but I'm skeptical that's going to make a difference. You can do that programmatically by placing the following lines at the top of your script:

setvalues NhlGetWorkspaceObjectId()
    "wsMaximumSize" : 500000000
  end setvalues

More commonly, people override the default by setting wsMaximumSize in the so-called ".hluresfile"; see:

Good luck!

Output is coming like below;

Hi,

The script and that dataset work fine on my system, and barely make a mark in the amount of memory consumed.  That message is coming from NCL itself, not from your system. Please try running this little scriptlet from within NCL, and report back to the group:

getvalues  NhlGetWorkspaceObjectId()
   "wsMaximumSize" : maxMem
end getvalues
print(maxMem)

Also, please report the results of "ulimit -a", as Gus advised.

Finally, do you have a file named ".hluresfile" (note the leading period) in your home directory?  If so, is there a line that begins "*wsMaximumSize: xxxxx", and what is the value for xxxxx?  Perhaps bump it up to 500000000.

Thank you..

But I am getting the error " dynamical memory allocation error".

How much disk space is required approximately to plot this data?

Thanks & Regards,
Soma

Hello,
I am trying to run the script vegland_1.ncl and for that I required sample input file.

Input file name: IGBPa_1198.map.nc<http://IGBPa_1198.map.nc>

Please kindly send me the input file.

Thanking you,
