[gem5-users] Re: Kernel Panic ARM Ubuntu

Hi, Based on my experience, more cores does not means more work, unless you specify more work. To elaborate: running same 1 thread application on 2 cores should be relatively close to 8 cores. More time will be needed (I think close to linearly) when you have more actual work, such as 8 threads

[gem5-users] Re: SPEC2017 Calculating CPI

Hi, I ran into similar issues before. Say I did, boot the cpus with atomic cpu, then warmup the application with atomic cpu, then restore with atomic cpu for ROI data collection. With this, the final numcycles are counted including boot+warmup+roi, not just roi. If you did a finalTick/ frequency

[gem5-users] Re: SPEC2017 Calculating CPI

This is what I did and made it work. Of course, I did this after I trace where they increment the cycles and made the changes make sense to me. I am using v22, so I would image it works for you. But, as Eliot pointed out, there are more places you need to check. I would suggest you starting with

[gem5-users] Any way to add randomization into full system simulation?

Hi, I am trying to run some benchmark on ARM full system simulation. Already use AtomicSimpleCPU to do the bootup and everything to speed up warmup, but still, ROI is few seconds of machine time, which takes up to few days to simulate. Also, for statistical confidence reasons, repeated run with

[gem5-users] Ethernet support for ARM FS simulation

Hi all, I noticed with the recent updates in ARM ISA support, now default machine setup is using VExpress_GEM5_V1, which is great, with the 2019 build kernel and boot loadert tested and everything. However, I also know that VExpress_GEM5 does not support ethernet device. What would be best setu
