Solaris is an illustration of an OS that combines both ULT and KLT

  2. Bulk of synchronization and scheduling of threads done in the user space
  3. The programmer may perhaps adjust the number of KLTs
  4. Process comprise the user's address space, process control block and stack
  5. User-level (threads library) threads invisible to the OS are the interface for application parallelism
  6. Kernel threads the unit that is able to be dispatched on a processor
  7. Lightweight processes (LWP) every LWP supports one or more ULTs and maps to exactly one KLT.
