Segmentation fault when L2 cache disabled

[andy-shiyi-liu]

I am running GPGPU-Sim with modified gpgpusim.config file to test performance under different setups. Based on configs/tested-cfgs/SM75_RTX2060/gpgpusim.config, I disabled L2 cache by changing line 114:

Then when I run GPGPU-Sim with L2 cache disabled, I met a segmentation fault.

I suspect this fault is caused by not detecting whether L2 cache is disabled when executing force_tag_access() during cudaMemcpy(). If not, could someone tell me a way to avoid this segmentation fault? Thanks!

I am running with GPGPU-Sim v4.2.1.
