No DRAM activity

[Sudhanshu Gupta]

Hi all,

I want to use GPGPU-Sim to collect memory statistics and am trying to run a small vector addition kernel using PTX simulation. After the application finishes execution, the output verification passes but there is no DRAM activity. I enabled the flushing of L2 cache after kernel completion, but that didn't help. Running the simulation in a debugger confirms that dram_t::push is indeed never called either. Does anyone know what's happening here?

Thanks,

Sudhanshu
