traj.gs

[Ted Pollock]

Hello All;

I am running the script traj.gs on some high temporal resolution MM5 data.
The script has to be run 49 times per output image file. The trouble is that
after around 5 to 6 trajectory calculations grads crashes with the following
error: Segmentation fault (core dumped). Each trajectory calculation runs
slower then the last so it is some kind of memory problem but the coredump
file size is only 5.2 Mb.

I have tried setting the memory limits and core dump size very high with
little success.

I am running Version 1.8SL9 on an SGI IRIX64.

Here is the script I'm using to run traj.gs.

  while (j<8)

    'run traj.gs 'LONb' 'LATb

    j=j+1
    LATb=LATb+dlat

  endwhile

endwhile
