COMBINED ULT/KLT APPROACHES

Idea is to merge the best of both approaches

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

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