Is there any option to limit the number of in-flight branches in the

Hi All,
I run this command on GEM5 and got nothing in the stats.txt
./build/X86

reset proprely, they appear to do so.
Does anyone has any insight or better understanding around this?

Hi Carlos,
Does this fault appear early on in the execution? Have you tried
booting with 1 core, create a checkpoint and then when restoring from it
(basically skipping boot) you can have multiple cores. I had a similar

Hi,
If I understand your commands properly, I think you compile spec for
x86_64 but your image is for the arm architecture. You need to compile
spec for arm as well. You can try cross-compiling, using qemu to chroot
to an arm linux image and compile spec from there or take a look at the
lin
What is the script you are running? For example if you used dumpreset
command, it will dump the stats until that point and then again at the
end of the execution (for the stats gathered after the dumpreset command).

Hi,
I have been running keras (python interface for tensorflow) in Gem5.
If I understand correctly you want to run a python script in Gem5 from a
C++ source file, correct? Gem5 already uses pytbind11 (which is a
header's only library simplifying embedding python code in C++ and vice
versa)
nstead of possible). The command I use to run is the following:
./gem5/build/ARM/gem5.opt \\
./gem5/configs/example/se.py \\
--cmd="401.bzip2" \\
--take-simpoint-checkpoint=./simpoints.pnts,./weights.wgts,1,5000
\\
--cpu-type=AtomicS
Issue resovled. Apparently the problem was that I was running multiple
simpoints on a shared filesystem and they were all modifying the content
of the folder "fs/", creating a race condition.

Hi Sam,
I am not sure how the python script works but I think what you want to
do can be achieved by using the --outdir=DIR (or -d DIR) command line
argument for the gem5 binary, not the script. For example I think the
correct way to do it in your example is this:
build/X86/gem5.opt --outdi
