SHMEM_CHAR_P(3)

💖 NAME 💖

Okay bestie, this is the SHMEM_CHAR_P(3) page from the Open MPI manual — and it's giving “tiny but mighty remote-write energy.” ✨

shmem_char_p(3), shmem_float_p(3), shmem_int_p(3), shmem_long_p(3), shmem_short_p(3), shmem_longlong_p(3), and shmem_longdouble_p(3) — these routines provide a low latency mechanism to write basic types (char, short, int, float, double, long, long long, long double) to symmetric data objects on remote PEs. Periodt. 💅

✨ SYNOPSIS ✨

C or C++:

#include <mpp/shmem.h>

void shmem_char_p(char *addr, char value, int pe);

void shmem_short_p(short *addr, short value, int pe);

void shmem_int_p(int *addr, int value, int pe);

void shmem_long_p(long *addr, long value, int pe);

void shmem_longlong_p(long long *addr, long long value, int pe);

void shmem_float_p(float *addr, float value, int pe);

void shmem_double_p(double *addr, double value, int pe);

void shmem_longdouble_p(long double *addr, long double value, int pe);

---

🦋 DESCRIPTION 🦋

These routines provide a very low latency put capability for single elements of most basic types. No cap, it's the little “just put this one value over there” moment. 🎀

The arguments are as follows:

• addr — The remotely accessible array element or scalar data object which will receive the data on the remote PE. It's the destination bestie on the other side. 🫶
• value — The value to be transferred to addr on the remote PE. This is the actual tea being sent. ☕
• pe — The number of the remote PE. Like, which PE are we sending this to? 👑

⚠️ Timing tea, important: As with shmem_put(3), these functions start the remote transfer and may return before the data is delivered to the remote PE. Use shmem_quiet(3) to force completion of all remote PUT transfers. Don't skip the quiet check if you need the delivery done-done. 😭

okay bye bestie 💖 — footer vibes: source/version says gitclone, Unreleased developer copy, and the page is SHMEM_CHAR_P(3). No date printed in this footer, so that's the whole cute sign-off. mwah 💋🌈
