How to control Main memory size in accelsim?

[SYYtera]

Hello, I'm beginner of this simulator. So I try to adjust the parameter of config file.

While adjusting it, I tried to reduce the main memory size of QV100 config file, but I was not able to find any other parameter to reduce it.

Is there any way to control main memory size while keeping bandwidth between GPU and HBM?

If I can give the effect of reducing the main memory size while maintaining the bandwidth between GPU & HBM without reducing the main memory size parameter directly, that's also good.

Best Regards.

PCI-E is not modeled, so the baseline assumption is the workload can fit within the memory.

Thus, memory size is not modeled.
What are you trying to study?

I wanted to see how performance changes as cache and memory size change in GPU models. So I changed cache parameter in config file but I couldn't find parameters about memory size.
Thank you for your response.

you can change the cache size. L1, L2, etc. But just not the memory (HBM).
