[gem5-users] Does KvmCPU gives timing information

Hello Everyone, Is there any notes or README that describes KvmCPU? Is it same as AtmoicCPU and the difference is, it is using the host computer's architectural resources? Also, can it be used to collect O3CPU timing information? Best regards, Abhishek

Re: [gem5-users] Multiple simultaneous benchmark run on same diskimage/kernel

Hi Ayaz, Thank you for your response. I have checked if any of the gem5 process was actually killed because of being Out of memory but it’s not the case. The simulations doesn’t use that much memory and I have checked occasionally to see the system resource usage and never found memory usage

Re: [gem5-users] Multiple simultaneous benchmark run on same disk image/kernel

Hi Reyad, Sharing the disk image and kernel should not be a problem. I will suggest you to make sure that the OOM (out of memory) killer is not getting activated on the system (usually logged in /var/log/messages). Regards, Ayaz On Fri, Feb 7, 2020 at 4:53 PM Hafizul Islam Reyad wrote: > > >

[gem5-users] Multiple simultaneous benchmark run on same disk image/kernel

Hi, I am new to gem5 and I was trying to run multiple benchmarks on gem5 to get some results for my research. I face a issue that whenever I run multiple gem5 simulations on one disk image, some of the gem5 process exits without giving any results or errors.    For example, I have about 20

[gem5-users] Perform multithreaded simulation in x86 o3 cpu model

Hello Everyone, I want to simulate multithreaded application on gem5. I tried gem5 SE model using m5 threads. I tried simulating examples in m5threads using 2 threads, I used test_lock example particularly. The gem5 commit I used is *82f6d6e90* The simulation starts but exits on its own without

Re: [gem5-users] Kernel Panic in FS ARM simulation

Thanks for the help and I found my error, I didnt know multiple image files were now supported so I was wrongly altering the fsconfig script.Now the simulation is sucessfully booting the operating system.On Feb 7, 2020 2:22 PM, Giacomo Travaglini wrote: Your log says: "No working init found"

Your log says: "No working init found" Are you sure you have a valid init script/executable in your disk image? Giacomo From: Iago . Sent: 07 February 2020 13:28 To: Giacomo Travaglini ; gem5-users@gem5.org Subject: RE: [gem5-users] Kernel Panic in FS ARM

[gem5-users] How to attach second image to full system emulation.

I've been trying to reproduce some tests i've done last year but with some of the latest updates to the tool the way to append a second image to the FSConfig.py script has changed, i've been trying to just change this: def makeCowDisks(disk_paths): disks = [] for disk_path in
