PPT-Efficient Deterministic Replay of Multithreaded Executions

in a Managed Language Virtual Machine Michael Bond Milind Kulkarni Man Cao Meisam Fathi Salmi Jipeng Huang Purdue Microsoft Ohio State 1 Nondeterminism is problematic Reproduce and Debug. washingtonedu httpsampacswashingtonedu Abstract The behavior of a multithreaded program does not depend only on its inputs Scheduling memory reordering timing and lowlevel hardware effects all introduce nondeterminism in the execution of multithreade Determinism and Randomness . Classical physics is deterministic!. If you know where you started you know where you are going. Randomness:. Quantum randomness is truly random and unpredictable. A lot of randomness is actually complexity and uncertainty. in a Managed Language Virtual Machine. Michael . Bond. Milind. Kulkarni. Man . Cao. Meisam. . Fathi. . Salmi. Jipeng. Huang. Purdue.

In an IMC campaign, it is important that every time the target is exposed to the message, no matter the vehicle, it reinforces the key benefits. . Look . to what visuals are being used in other materials: consider color, spokesperson or character representatives, headline styles, or the execution techniques used elsewhere in the promotional mix to bind the IMC pieces together..
