The emulator produces traces and dependency information. The simulator uses those traces to predict performance on target architecture. During emulation, you run the application as if you have a large number of processors (using Charm++'s normal virtualization capabilities).

Hi,
I look at the webpage(http://charm.cs.illinois.edu/research/bigsim).
Both BigSim Emulator and BigSim Simulator can be used to simulate PetaFLOPS Supercomputers. What's the difference? How should I to select?

Thanks.

Qin
