I would like to write a shellscript that reads the current CPU utilisation on a per-core basis. Is it possible to read this from the /sys directory in Linux (CentOS 8)? I have found /sys/bus/cpu/drivers/processor/cpu0 which does give me a fair bit of information (like current frequency), but I’ve yet to figure out how to read CPU utilisation. In other

Estimate Core capacity required based on load?
I have quad core ubuntu system. say If I see the load average as 60 in last 15 mins during peak time. Load average goes to 150 as well. This loads happens generally only during peak time. Basically I want to know if there is any standard formula to derive the number of cores ideally required to handle the given
Is it safe to use all 4 cores of your pc to train a machine learning model
I am training a ml model on my ubuntu 16.04 . I wrote a code that utilizes all 4 cores of my pc. I doubt if this would lead to some sort of crash Using htop command on terminal shows me my 100% usage of all 4 cores along with many information including /usr/lib/xorg/Xorg -core:0 …….. no listen Answer It
Using Cgroups to limit cpu usage
I am trying to use cgroups in order to limit the CPU usage. I am using this guide https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Resource_Management_Guide/sec-cpu_and_memory-use_case.html My /etc/cgconfig.conf file is the following My cgrules.conf is the following Althouth when I try to run: I see that the cpu usage in 100% for the users belong to group wheel and test1 I have checked the services with service
Getting cpu cycles using RDTSC – why does the value of RDTSC always increase?
I want to get the CPU cycles at a specific point. I use this function at that point: (editor’s note: “=A” is wrong for x86-64; it picks either RDX or RAX. Only in 32-bit mode will it pick the EDX:EAX output you want. See How to get the CPU cycle count in x86_64 from C++?.) The problem is that it
