High Performance Fortran compiler?

I am completely new to High Performance Fortran but I am interested
in getting to learn about it and experiment with it. I am therefore
looking for a freely available HPF compiler. My requirements are:

* It should support as much as possible the latest HPF Language
Definition as in http://hpff.rice.edu/versions/index.htm

* It should be freely available (preferably Open Source or Public
Domain software). And I don't like trial periods of 30 days etc...

I came across the list at http://hpff.rice.edu/compilers/index.htm which
mentions G95 and SHPF... but since I'm not sure in how far G95 supports
the latest HPF Language Definition I guess that SHPF is my best option?
Is this correct?

Taking into consideration my requirements, what would be the best compiler
for me to pick?

Thanks,
Bart
