[parsec-users] Serial implementation of Canneal

I noticed that the serial implementation of Canneal uses atomic
pointers even though they are not necessary. This seems to carry a
fairly high overhead and gives a false sense of  performance
scalability for this application.

I rewrote the single threaded implementation to use regular pointers
and found that the performance increased by 40%.
