On SLES 64 there are two versions of the library libpthread.a - /usr/lib64/libpthread.a & /usr/lib64/nptl/libpthread.a.

What's the difference?

I'm guessing the later maybe implements the Native POSIX Thread

Library

while the former uses what? ? (LinuxThreads?, Next Generation POSIX Threads?).

Linux Threads is the old version of threads. NPTL is the new version of threads. While I don't have the details, NPTL benchmarks much faster than the old thread library and also scales better across processors.
