Dear Chang,
this is hardly a matter of configuration but a question of programming
(meaning you cannot change it unless you modify the source code and
recompile). You can run a program of which you know it is
parallelised, e.g. XDS, shelxl, shelxd, and check with the command
'top' that your %CPU is about 400%.
You can also get the program i7z for more detailed information about
the status of your CPUs.
Phaser is parallelised, but I dare say it is rather an exception
within the ccp4 suite.
So all you can do is encourage the developers of cpu-demanding
programs to spend time on parallelising their code - XDS is one of the
most impressive examples of how much this can be worth in the context
of acceptance and propagation.
Best,
Tim
