ATOMIC_MAX(3clc)

💖 ATOMIC_MAX(3clc) 💖

okay bestie, this is a page from the OpenCL Manual and it's about atomic_max — the icon, the moment, the function. let's get into it 🫶

---

✨ NAME ✨

atomic_max — atomic_max functions. yes that's the whole vibe, no notes 💅

int atomic_max(volatile global(3clc) int *p, int val);

unsigned int atomic_max(volatile global(3clc) unsigned int *p,
                        unsigned int val);

int atomic_max(volatile local(3clc) int *p, int val);

unsigned int atomic_max(volatile local(3clc) unsigned int *p,
                        unsigned int val);

🌸 DESCRIPTION 🌸

so here's the tea, bestie ☕ — you read the 32-bit value that's chillin' at the location pointed to by p, and we call that lil guy old. then you compute commonMax(3clc) of (old, val) and store that result right back at the location pointed to by p. and the function returns old. periodt ✨

and ooooh, a 64-bit version of this function exists too — it's called atom_max(3clc), and it's enabled by cl_khr_int64_extended_atomics(3clc). iykyk 👑
