I have access to a centos machine with many cores, so I want to start 
writing parallelised code on it. This is probably naive, but *is using the 
code in sage.parallel the best way to write parallel code in sage*? 

I started using the @parallel decorator but then I found the optional 
packages openmpi and mpi4py and wondered if it would be better to use these 
instead, except it seems that the packages are no longer maintained (and 
hence not useful?) as "new style" packages for them don't seem to exist. I 
am confused, however, because mp4py is the main topic of the thematic 
tutorial 
http://doc.sagemath.org/html/en/thematic_tutorials/numerical_sage/parallel_computation.html
 

which suggests that it is still being used.
