PPT-Process Synchronization Readings: Chapter 5

Issues in coopering processes and Threads data sharing Shared Memory Two or more processes share a part of their address space Incorrect results whenever two processes or two threads of a process modify the same data at the same time. wait Bi l s gna C lock acquire D lock release E signalAll Hoare monitor semantics Assume thread T1 is waiting on condition Assume thread T2 is in the monitor Assume thread T2 calls x signal T2 ives u monitor T2 blocks gp T1 takes over monitor run Hakim Weatherspoon.
