Hi Andrea --

We're working towards a feature freeze deadline for the next release at 
present, so it may be a bit before we're able to look at your code in 
detail.  The "only using 2 CPUs" issue is surprising though.  I'm curious:

a) How are you determining this?

b) How many messages do you get if you compile and run
    examples/hello5-taskpar.chpl?

If you haven't found it yet, be sure to read $CHPL_HOME/PERFORMANCE and, 
if you aren't, to throw the --fast flag when compiling for performance 
runs.

Hope to spend more time on this soon, but curious for your answers to
the above,
-Brad
