[gem5-users] GemsFDTD stats with X86_SE

[Mahmood Naderan]

Hi
Some one has tried simulating 459.GemsFDTD in SE mode?
I tried X86_SE with these options:

fast forward = 2,000,000,000 instructions
max ticks = 100,000,000,000 ticks
cpu type = detailed
L2 = 1MB, 16
L1 = 32kB, 4


however the  output stats are strange:
sim_insts                                                    2053846134
system.switch_cpus.ipc                                         0.538461

system.l2.replacements                                                0
system.l2.demand_accesses                                             1
system.l2.demand_misses                                               1

system.cpu.icache.replacements                                        1
system.cpu.icache.demand_accesses                                    29
system.cpu.icache.demand_misses                                       5

system.cpu.dcache.replacements                                        0
system.cpu.dcache.demand_accesses                                     0
system.cpu.dcache.demand_misses                                       0

As you can see, D-cache has not been accessed in 100B ticks. Also L2
is accessed only one time.

I have not tried ALPHA isa. If you have any idea about that please let me know
