NPTL Threading on SMP/NUMA

I am running an application which runs many threads under a single process. The system is running 2.6.18-3 and NPTL 2.3.6 on Dual Opteron 246HE's.

All of the load is on 1 CPU per top, mpstat, etc. Does NPTL provide a method to spread threads our over multiple CPU's even if they exist under a the same parent process? I am trying to determine if this is a limitation in NPTL or in the application I am running.

Thanks,
