Is the script being run in parallel? If so, does it crash if you run it on only one core? Nathan On Monday, October 17, 2016, tazkera haque <h.tazkera@gmail.com> wrote:
HI people,
I am using yt 3.3.1 and submitting my SLURM script to stampede. I was using this script to find abundances of C, O etc through checkpoint files in FLASH. while my script worked fine with old yt (3.1) , suddenly it crashed today and returned me the following error:

I was wondering if there is something wrong with my code or the new yt. I am also attaching my code here to look at. Thanks in advance
