    In the output file of the profile results, you will find the memory traffic behavior of the kernel of interest. You can then further process and analyze these results.
 
    We cannot pre-assign names due to libraries like Triton having internal implementations that call extra kernels. Filtering based on names is not feasible. To address this, we run profiling multiple times (e.g., three) to observe log outputs, then run the tested program several times (e.g., five) to identify patterns. This helps us pinpoint actual kernel calls and post-process the ncu profiling logs to compute network traffic over the memory hierarchy.

+### Run the test
+
+We have prepared a testing environment on the provided server to run the tests.
+
+1. [run_all_ncu_cutlass.sh](../run_all_ncu_cutlass.sh) is used to run the test for flash attention2 implmented in CuTlass.
+
+  ```bash
+   sudo -i # Switch to root account
+   cd /home/sosp/nnfusion/artifacts
+   ./run_all_ncu_cutlass.sh
+   ```
+
+2. [run_all_ncu_flash2.sh](../run_all_ncu_pt.sh) is used to run the test for flash attention2 implemented in PyTorch.
+
+   ```bash
+   sudo -i # Switch to root account
+   cd /home/sosp/nnfusion/artifacts
+   # Choose the environment you want to test
+   source /home/sosp/env/torch_env.sh
+   ./run_all_ncu_flash2.sh
+   ```
+
+3. [run_all_ncu_ft.sh](../run_all_ncu_ft.sh) is used to run the test bigbird and flash attention implemented in FractalTensor.
+
+   ```bash
+   sudo -i # Switch to root account
+   cd /home/sosp/nnfusion/artifacts
+   ./run_all_ncu_pt.sh
+   ```
