data flow in cuda-sim

[Shougang Yuan]

Hi, All,

Have any of you tried to get the data flow of applications from the cuda-sim? If we have one memory address in gpgpu-sim, and we want to know the real data of the application corresponding to this address, how can we get it in the simulator?

Thanks and regards

Shougang

Suppose you're using execution-driven mode. 

This is the memory struct that stores real data of the app

https://github.com/accel-sim/gpgpu-sim_distribution/blob/dev/src/abstract_hardware_model.cc#L182

And here is the read function

https://github.com/accel-sim/gpgpu-sim_distribution/blob/dev/src/cuda-sim/memory.cc#L134

And you can reference how to get a read a value from the memory struct from the functional implementation of load inst

https://github.com/accel-sim/gpgpu-sim_distribution/blob/dev/src/cuda-sim/instructions.cc#L3398

Hope these help!

Thanks,

Junrui
