CUfilePerGpuStats(3)

💅 CUfilePerGpuStats(3) 💅

okay so welcome to the CUfilePerGpuStats(3) page, straight out of the Library Functions Manual bestie — this is the whole vibe, we're doing per-GPU statistics today and we're doing them thoroughly 🫶

---

🌸 NAME 🌸

CUfilePerGpuStats — the per-GPU statistics structure used in Level 3. that's the whole pitch, no notes, she said what she said 💅

✨ SYNOPSIS ✨

#include <cufile.h>

🦋 DETAILED DESCRIPTION 🦋

Per-GPU statistics structure used in Level 3. that's the official description, word for word, and it's giving "confident but mysterious" — the main character energy of documentation ngl 🌈

👑 FIELD DOCUMENTATION 👑

okay so here's the part where the page goes through every field one by one. and the notes for each one? literally nothing else. she lists the field, she moves on. minimalism. we respect it 💀

real talk bestie: the page doesn't give descriptions beyond the field signatures above, so i'm not gonna sit here and make stuff up about them. what you see is what the docs say, periodt 💅
