Foil 10 Discrete Event Simulations

From Parallel Programming for Particle Dynamics Extra Foils Computational Science CPS615 -- Spring 2000 Semester. by Geoffrey C. Fox
1 Suppose we try to execute in parallel events E1 and E2 at times t1 and t2 with t1 > t2.
2 We show the timelines of several(4) objects in the system and our two events E1 and E2
3 If E1 generates no interfering events or one E*12 at a time greater than t2 then our parallel execution of E2 is consistent
4 However if E1 generates E12 before t2 then execution of E2 has to be rolled back and E12 should be executed first
