Like LinuxThreads, NPTL is a 1:1 threads library. Threads created by the library (via pthread_create) correspond one-to-one with schedulable entities in the kernel (processes, in the Linux case). This is the simplest of the three threading models (1:1, N:1, and M:N). New threads are created with the clone() system call called through the NPTL library. NPTL relies on kernel support for futexes to more efficiently implement user-space locks.
