Hi Everyone , I am doing a full system simulation on ARM using fs_bigLITTLE.py and fs_power.py , I am trying to import numpy library in my python script but it takes 3-4 days and is still running but the library is not imported , how can I speedup this , once I import I can checkpoint but somehow its very slow and takes a really long time.please provide me some suggestions on this. Thank you in advance Regards Srinija

You can run to checkpoint using a simple and fast cpu model, such as the atomic simple cpu. Then you can run after checkpoint with a more complex cpu model. Of course, the system may already be doing that for you. Another possible issue is whether you're firing up a gazillion server processes in the OS. Trimming down the boot sequence helped me save a lot. HTH Eliot Moss

I am using atomic cpu model ,chekcpointed the system after the boot , I am also trying to import this library , using atomic CPU model again so that I can checkpoint it once its loaded but it does not even after this , its been running for 3-4 days now but has been stuck at this import line I also tried this method of kernel-init ./build/ARM/gem5.opt configs/example/arm/fs_bigLITTLE.py --kernel=/home/saras/gem5-resources/src/arm-ubuntu/gem5/full_system_images/binaries/vmlinux.arm64 --disk=/home/saras/gem5-resources/src/arm-ubuntu/gem5/full_system_images/disks/arm64-ubuntu-server.img --caches --cpu-type=atomic --kernel-init=/bin/bash To speed up the boot up And it is successful however the import numpy statement takes forever to run Regards Saras On Tue, Jan 2, 2024 at 9:35 AM Eliot Moss <moss@cs.umass.edu> wrote: > On 1/2/2024 9:28 AM, saras nanda via gem5-users wrote: > > Hi Everyone , > > > > I am doing a full system simulation on ARM using fs_bigLITTLE.py and > fs_power.py , I am trying to import numpy library > > in my python script but it takes 3-4 days and is still running but the > library is not imported , how can I speedup this > > , once I import I can checkpoint but somehow its very slow and takes a > really long time.please provide me some > > suggestions on this. > > You can run to checkpoint using a simple and fast cpu model, > such as the atomic simple cpu.
