Hi Geoffrey,

The operation to combine profile and phase plot data after running in parallel was missing, so what you were seeing was the results from only one of the processors.  I have just filed a pull request to fix this.  Now, I get the same results independent of processor number.  Please. have a look at the PR here and test it out if you can.

Hi Geoffrey,

Britton and I verified you are correct, there is a problem with the
ProfileND objects not conducting their parallel reduction operation.
A fix is forthcoming.
