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…

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 giv…

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 tha…
