A couple points with regard to the run-job script: If you run an out-of-order simulator like UniFlex.OoO, you need to also include the "-ma" flag.
In general, Flexus supports creating flexpoints with Trace simulators. You seem to be trying to write a flexpoint (the "-fxpt-out" option) with an out-of-order simulator. This may work correctly, but is not behavior we exercise or test. If you intended to read the flexpoint instead, use the "-fxpt" option.
