Re: Increasing stacksize on Mac OSX

I have 6 GB of memory on my Mac. I do believe that my script requires more memory than 64 MB. When I ran it on Linux systems I had unlimited stacksize and it ran without any problems.

I came across this NCL for Mac page, which suggested making the stacksize unlimited. That should mean it's possible (unless whoever wrote this page never actually tried to do that themselves):

http://www.ncl.ucar.edu/Download/macosx.shtml

If I can't figure out how to increase the stacksize, that will likely cause me problems when I try to run WRF as well, because 64 MB is pretty darn small...

I haven't been able to find a way to increase the stacksize to unlimited, or even anything larger than that. An NCL script that I have runs just fine on Linux systems, but when I run it on my new Mac, I get errors like this one:
