I wonder what the scaling is like as we > approach larger N. :-) I've got a patch to do this, prompted by the use of UltraSPARC-T2 machines with 8 cores/8 strands which are quite slow on their own: [build, testsuite, v3] Increase gcc, g++, gfortran and libstdc++-v3 testsuite parallelism http://gcc.gnu.org/ml/gcc-patches/2010-07/msg01633.html but haven't yet incorporated Jakub's comments.
