If native execution takes 5 minutes and you set the frequency to 1GHz (in the simulator) and CPI is 1 then:
5*1B = 5B instructions. Depending on the speed of your host computer and the binary you use (m5.debug or m5.fast) if the simulator speed is 1M instructions per second then simulation of a 5 minute application will take 5B/1M=5000 seconds. I think this has been discussed before. // Naderan *Mahmood; On Tue, May 22, 2012 at 11:52 AM, Bojun Ma <[email protected]> wrote: > Hi, all > I cross-compiled SPEC benchmark and got the ARM binaries of CPU2000. > I'd like to run it in ARM SE mode. > ( I didn't use cpu2000.py) > > Take gzip as an example, I put both the binary of gzip and one of its > input( input.random) in the directory of gem5. > > I used the command line like this: ( I didn't use cpu2000.py) > > command line: build/ARM/gem5.opt configs/example/se.py --cmd=gzip > --input=input.random > > The simulation seems stops but there is no error information,like this: > > Global frequency set at 1000000000000 ticks per second > 0: system.remote_gdb.listener: listening for remote gdb #0 on port 7000 > **** REAL SIMULATION **** > info: Entering event queue @ 0.
