HPL_barrier(3)

💖 HPL_barrier(3) 💖

ok so bestie, welcome to the HPL Library Functions corner of the man pages 🎀 this one's HPL_barrier and it's literally the "wait for everyone" function, no cap.

✨ NAME ✨

HPL_barrier — Barrier operation. 🚧

🌸 SYNOPSIS 🌸

#include "hpl.h"

int HPL_barrier( MPI_Comm COMM );

🦋 DESCRIPTION 🦋

Okay so here's the vibe: HPL_barrier blocks the caller until all process members have called it. Like, it's the group chat "everyone react when you're here" energy 🫶

The call returns at any process only after all group members have entered the call. So nobody gets to leave the party early — everyone's in the call, then everyone's out. Periodt. 👑

ngl if you're the impatient type, this function will humble you. it does not care about your schedule, bestie. it waits. 💀

💅 ARGUMENTS 💅

• COMM (global/local input) — MPI_Comm The MPI communicator identifying the process collection. it's giving "who's invited to this barrier" 🌈 it's an input, it's global/local, and it is exactly type MPI_Comm, don't come at me with anything else.
