Comment 6 for bug 1656728

I'm still confused about exactly what is happening in the runs that fail, but by disabling LHAPDF, I was able to successfully run on our cluster with the modification I made to cluster.py. It is unclear to me if the error reflects something problematic about my LHAPDF installation or is a side effect of my modification to cluster.py. (I have successfully run some simpler processes, like p p > t t~, with LHAPDF turned on, so it doesn't always fail.)

In any case, I can get by without the systematics information, so I guess my current setup is good enough for now.

Thanks for your help.
