[gem5-users] Re: How to change voltage and frequency of individual ComputeUnit for GPU?

2023-04-04 Thread Srikant Bharadwaj via gem5-users
Hi Kazi, Matt's assumption is correct. Voltage does not affect the correctness of the model. You can see the scope of the voltage domain in src/sim/voltage_domain.cc Changing the voltage when the DVFS is enabled changes the clock frequency according to the perf levels that have been set. One can

Hi, I did not understand how the proposals in the above content would affect the simulation results. What I'm curious about is whether the above has been updated to the current Gem5 version! Regards, Haseung

[gem5-users] Kernel Panic ARM Ubuntu

2023-04-04 Thread Νικόλαος Ταμπουρατζής via gem5-users
Dear gem5 community, I have successfully simulated the HPCG benchmark using ARM Ubuntu in gem5 in 2 cores. However, when I try to simulate it using more cores (i.e. 8 cores) it takes more simulated time, and I get the following kernel panic after approximately 20 hours of simulation: [

[gem5-users] Architectural Registers Mismatch in gem5

2023-04-04 Thread Nitesh Narayana Gondlyala Sathya via gem5-users
Hi I was playing with the number of physical registers for an experiment. I observe the following: ARM config file has numPhysVecRegs to be 48. This means after gem5 initializes the rename map (in cpu constructor src/o3/cpu.cc ) the size of the free list should be 48 - architectural registers,
