[ncl-install] ncl on Cray systems

[Jatin Kala]

Hi,
I had some trouble getting ncl (pre compiled binary) to work on a Cray system before. Here is a snippet of the email from the sys admin:


####
export NCARG_ROOT=/group/y98/ncl-6.2.1
export NCARG_USRRESFILE=$NCARG_ROOT/hluresfile
export MY_TMP=/scratch/y98/[your-user-id]/tmp

TMPDIR=$MY_TMP aprun -n 1 $NCARG_ROOT/bin/ncl plot_entropy_examples.ncl


The key here is that the environment variable NCARG_USRRESFILE must be set.
This is causing the SEGV observed earlier. The file need not exist, or may be empty,
but the environment variable must be set.

I recommend you create a temporary directory and specify MY_TMP as above. By
default, temporary files are written to /tmp, which on Magnus is actually memory.
This can create problems if you have large temporary files.

Hope this helps. We did manage to get ncl to work on this cray machine without having to build from source.
Cheers,
Jatin
