Hello, I use gcn3_x86 in gem5 to test the impact of interference between gpu programs and cpu program memory access requests on cpu and gpu performance. By modifying apu_se.py, I specify the test program for gpu as square, and the cpu test program as 401 of spec2006. I wanted to see if my idea would work, so I specified a maximum instruction count of 1000000000. However, the program does not stop after execution, and no error is reported. There is no data in the output file stats.txt.
