In Solaris 9 and Solaris 10, there is a one-to-one mapping between ULTs and LWPs. In Solaris 8, a single LWP supports one or more ULTs.
a. What is the possible benefit of allowing a many-to-one mapping of ULTs to LWPs?
b. In Solaris 8, the thread execution state of a ULT is distinct from that of its LWP. Explain why.
c. Figure 4.19 shows the state transition diagrams for a ULT and its associated LWP in Solaris 8 and 9. Explain the operation of the two diagrams and their relationships.
