GMMUCache Hit/Miss Pattern Remains Unchanged

[Kranti-Ingale]

I am running the FIR application with the following command:
./fir -report-gmmu-cache-hit -report-tlb-hit-rate -timing -use-unified-memory -gpus=1,2,3,4 -trace-mem -length=4096000

The GMMUCache statistics I observe are:
GPU[1].GMMUCache hit 315
GPU[1].GMMUCache miss 2005
GPU[1].GMMUCache mshr-hit 0

GPU[2].GMMUCache hit 0
GPU[2].GMMUCache miss 2005
GPU[2].GMMUCache mshr-hit 0

GPU[3].GMMUCache hit 0
GPU[3].GMMUCache miss 2005
GPU[3].GMMUCache mshr-hit 0

GPU[4].GMMUCache hit 0
GPU[4].GMMUCache miss 2005
GPU[4].GMMUCache mshr-hit 0

I have noticed that varying the -length parameter does not seem to affect the GMMUCache hit/miss pattern—it remains the same across different runs. Am I missing something in my modifications, or is this behavior expected? Any guidance would be appreciated. Thank you.
