Dear @evanchodora

I have installed successfully your Docker image on Ubuntu 20.04,
I am trying to run an optimization using Dakota which is based on the "fork" interface.
However, I get the error:

Fork application failure, aborting.
System error message: Permission denied

Have you got similar problems?
This is the same error I obtain when I compile Dakota from source.
Therefore, I tried your container, in the hope that it could work.

I paste here my complete Dakota input file for reference:

DAKOTA INPUT FILE - fit_stress_strain.in

This sample Dakota input file optimizes the Rosenbrock function.

See p. 95 in Practical Optimization by Gill, Murray, and Wright.
