💅 LPARNUMASCORE(8) — the lparnumascore glow-up 🦋

okay bestie, so this one's from the Linux on Power Service Tools crew, and it's literally called lparnumascore — the icon, the moment, the NUMA affinity score checker for the LPAR you're running in right now. no cap. ✨

🌸 NAME 🌸

lparnumascore — displays the NUMA affinity score for the running LPAR 💖

🎀 SYNOPSIS 🎀

lparnumascore [-c | -d ]

that's it. that's the whole vibe. two flags, maximum slay. 🫶

✨ DESCRIPTION ✨

so the lparnumascore command is your new fave for displaying the NUMA affinity score for the running LPAR. and what does each score even mean? okay so — every score reflects the amount of resources the Linux kernel is seeing as bound to a node while the hypervisor has moved that resource to another node. like, the kernel thinks it knows where things live and the hypervisor is lowkey moving furniture around behind its back. 😭

the score is a number between 0 and 100. so:

  • a score of 100 means all the resources are seen correctly — perfect, iconic, no notes 👑
  • a score of 0 means all the resources have been moved to different nodes — truly the worst-case scenario, it's giving chaos 💀

and the important part: there's a dedicated score for each resource type. so they're not all squished into one number, each resource gets its own vibe check. 🌈

💅 OPTIONS 💅

  • -c <resource type> — displays the score for this type of resources. the valid resource types are "mem" for memory and "cpu" for cpu's. by default, the score for each of the supported resources is reported. so if you don't pass -c, you get the whole lineup. slay. ⭐
  • -d <detail level> — enables debugging output. and when you're displaying memory information, this flag will also enable printing information about LMBs not currently owned by the system. so yeah, extra tea with your tea. 🔥
real talk: the resource types are literally just "mem" and "cpu" — don't go inventing new ones, bestie. 🙈
