Hi,
Gabriel
I'm not interested in a specific gem5 component. I have a microbenchmark
that makes use of the srand and rand functions with srand() being seeded by
using time.
struct timeval t1;
gettimeofday(, NULL);
srand(t1.tv_usec * t1.tv_sec);
I assume that gem5 always uses the same time for
Hi,
I have followed the instructions in the post below in order to introduce
randomness between different runs of gem5.

However, it does not seem to work. I'm producing random numbers in my
program by seeding srand with time and
Hi Gabriel,
I've followed the instructions you have provided but I'm still getting the
same numbers on every gem5 run. The changes I made to se.py are the
following.

Hi,
I have created a new stat of type Formula in the xbar.cc/hh files. There I
aggregate all the different transDist types. I'd like to use this newly
created stat to compute another stat in the BaseCPU object. What is the
best way to have access to it (i.e., allTransactions stat) from BaseCPU?
Hi,
I have some questions about the power model in gem5.
- In what extent is it implemented? I'm mainly interested in a power model
for the CPU. Is there one?
- I have seen a python configuration script (fs_power.py) for ARM. Is there
a power model only for the ARM architecture?
- If yes, can it

Hi,
I've tried running the SPEC2017 benchmarks in FS mode of gem5 using the
instructions/files provided by the gem5 resources page.
https://gem5.googlesource.com/public/gem5-resources/+/refs/heads/stable/src/spec-2017
I've also followed the step by step instructions in the git repo for

Hi,
Building on top of my previous question and making it a bit more general.
Is there a way to access stats in a somewhat global manner? Let me explain
that with an example. During program execution, I need to know the number
of instructions committed and the MPKIs for L1 and L2. On every commit
Hi,
I want to run some tests for phase predictors using cache stats (e.g., L1
and L2 MPKIs). I need access to those stats during program execution, in
order to both keep a log of these and make predictions based on them. What
is the best way to access them? Would this be done through the cache.cc
