Hi Vicente,
I've executed your parallel_sort2.cpp with NN = 10000000 on a core 2 duo E6600 
(with  BOOST_BIND_WORKER_TO_PROCESSORS, BOOST_DISABLE_ASSERTS and -02)

std::sort: reverse 0..10000000 158 milli seconds
std::sort: 0..10000000 148 milli seconds
boost::sort: reverse 0..10000000 158 milli seconds
boost::sort: 0..10000000 148 milli seconds
parallel_sort 5000000:  reverse 0..10000000 145 milli seconds
parallel_sort 5000000:  0..10000000 121 milli seconds
parallel_sort 2500000:  reverse 0..10000000 169 milli seconds
parallel_sort 2500000:  0..10000000 148 milli seconds
parallel_sort 1250000:  reverse 0..10000000 190 milli seconds
parallel_sort 1250000:  0..10000000 166 milli seconds
parallel_sort 625000:  reverse 0..10000000 201 milli seconds
parallel_sort 625000:  0..10000000 184 milli seconds
parallel_sort 312500:  reverse 0..10000000 216 milli seconds
parallel_sort 312500:  0..10000000 203 milli seconds

I've added your example - thx.

Oliver
