Debugging HPF with TotalView

For a parallel debugger to be truly usable with HPF, it should display your original HPF code in its source window. TotalView does this for pghpf programs.

It is also possible to retrieve and plot a distributed data vector. Here is a display of every 25th value of a 500-element vector that is distributed across 4 processors.

If it is a two-dimensional array, you can also get a data-value histogram.
