CPU usage on dual socket motherboard

us flag

Ubuntu's system monitor shows CPU usage for each core separately. I have a motherboard with two CPU sockets and want to know how much CPU on socket0 is loaded and how much CPU on socket1 is loaded. How can this be done?

The reason I want to know this is that when I run a specific program, the CPU on socket1 is much hotter than the CPU on socket2. First, I'm going to know if the two CPU's are loaded equally. Then, if that is the case, I can be sure that it is an issue with the cooling system (i.e. Fan, Heatsink, thermal paste, etc.).

The CPU cores in the graphs will be sequential. If your CPUs have 12 cores each (for example), then the first twelve numbers will be for Socket 0 while the latter 12 will be for Socket 1. I do not believe there is anything in the default utilities that will show details on a per-socket as an aggregate

You can try command like

sar -P 0-5,12-17 -u 1

where -P specifies the CPU core, -u specifies the display interval.

Just check the cpu usage in different sockets at the same time and you can check weather two CPUs are loaded equally.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
