Running GEM5+Ramulator with se.py+ruby with the new patch about ramulator

[SaugataGhose]

Oh I see there's a typo in README.md. The --ramulator-config argument takes in a filename, for a file that contains the configuration parameters of Ramulator. We've included an example file, gem5-config.cfg, that contains a DDR3 configuration. If you try --ramulator-config=/path/to/ramulator/gem5-config.cfg, does that work?

[dongha]

works. thanks!

[astromonk2013]

Could you please tell me if gem5-config.cfg still exists?Thanks

[i7mist]

We now use a unified config file for all modes, i.e. there isn't a config file specifically for gem5 now, and you can use the config file in configs dir.

Thnaks, wanted to use the DDR3 config option.
Also getting a build error ramulator+gem5, any insights would be great:

It's duplicate question. Please see this thread: #20

Thanks a lot!!

[astromonk2013]

This is the command i am using, please advice
./build/X86/gem5.opt ./configs/example/se.py --mem-type=ramulator --ramulator-config=/home/ramulator-master/configs/ALDRAM-config.cfg -c tests/test-progs/hello/bin/x86/linux/hello

[i7mist]

Hi, can you open another issue? The problem is not related with the original one

[astromonk2013]

SUre, apologize.Will open another issue
