Many-to-Many Model Allows many user threads to be mapped to many kernel threads Allows the operating system to create a sufficient number of kernel threads Solaris to version 9 Windows NT/2000 with the ThreadFiber package Two-level Model Similar to M:M, except that it allows a user thread to be bound to kernel thread Examples IRIX HP-UX Tru64 UNIX Solaris 8 and earlier
