[gem5-users] gem5 stable release proposal [RESULTS]

[Bobby Bruce]

Dear all,

Thank you to all those who voted and provided us with valuable feedback on
the future direction of gem5. Voting is now closed and I've tallied the
votes. There appears to be a clear favored direction:

- The master shall be stable (13 votes to 3).

- gem5 will be released 3 times a year (11 votes to 3).

Given this result we will proceed with the release of gem5 19 in the coming
weeks, to exist on the stable master branch, with development moved towards
a new "develop" branch. I shall update the relevant documentation and will
send email updates as and when this is incorporated. We do not intend to
release gem5 19 with much fanfare; we consider it more of a "baseline"
release of gem5, as it exists now, in a relatively stable state. gem5 20
will be released in approximately 3 months time.

Kind regards,
Bobby

Re: [gem5-users] Run CPU 2006 benchmark on gem5 fs mode

[ABD ALRHMAN ABO ALKHEEL]

Hi Dimitrios, I appreciate your help. How I can run the benchmark for one 
million instruction in the FS mode. In SE mode I used -I 100 . Any help 
would be appreciated. Best Regards

Hi,

Here is an example of an .rcs script.  As Ciro told you, first you need to have 
a bootable image, optionally create a checkpoint after boot and finally add the 
benchmarks to the cd image.

#/bin/bash
cd 
/your/path/SPEC_CPU_2017/benchspec/CPU/627.cam4_s/run/run_base_refspeed_aarch64-64.
/sbin/m5 dumpresetstats
/yourpath/SPEC_CPU_2017/benchspec/CPU/627.cam4_s/exe/cam4_s_base.aarch64-64
/sbin/m5 exit

In the example above you simply cd to the directory of the benchmark you want 
to use and then run it.  /sbin/m5 dumperesetstats resets your statistics 
counters and exit is used to finish the execution.  Note I use spec 2017, which 
I found that it's best to run directly as I do above than use their 
infrastructure.  Problem is that FS is too slow and you waste a lot of time 
running their python scripts.  Also, I would encourage you to learn about 
simpoints if you plan on running SPEC CPU 2006 with 
anything more than the test inputs.  Running with ref will take days/weeks.

Best,

Dimitrios Chasapis

[gem5-users] In-flight conditional branches in O3

[Dimitrios Chasapis]

Hi,

Is there any option to limit the number of in-flight branches in the 
pipeline of the O3 CPU model?  I wasn't able to find one.


Best,

Dimitrios Chasapis
