num_processors() reporting the wrong number fo Processors

Hi,
I'm running a parrallel vsip++ program on a Xenon with 2 processors and 8 cores. Installed is the light version of vsipl++ with no options to ./configure. In my program I print out the return value of num_processors() for verification purposes and it returns 1 instead of the 8 I might expect.
I figure this is could be due to two reasons:
1. VSIPL++ lite doesn't support parallel features. It'd be nice if the differences in the lite version were specified somewhere but the problem is fixed once we get the commercial version.
2. During installation I was supposed to include an option to enable parallel support but I didn't and so it doesn't work. I didn't find anything in the "Getting Started" guide which mentioned enabling built-in parallel support (just external libraries like MPI) but if this is the case I would be ever grateful if someone could provide the correct options to use.
Thanks,
Erek
