SHMEM_CHAR_G(3)

okay bestie, welcome to the Open MPI page for SHMEM_CHAR_G(3) — it’s giving “tiny remote read, major main character energy,” and honestly? iconic 🎀

✨ NAME ✨

These routines are your low latency mechanism to read basic types — char, short, int, float, double, long, long long, long double — from symmetric data objects on remote PEs. Fr fr, that’s the whole vibe.

• shmem_int_g(3)
• shmem_long_g(3)
• shmem_short_g(3)
• shmem_longlong_g(3)
• shmem_longdouble_g(3)

And yes bestie, the synopsis below also brings shmem_double_g to the group chat 👀

🌸 SYNOPSIS 🌸

C or C++:

#include <mpp/shmem.h>

char shmem_char_g(const char *addr, int pe);

short shmem_short_g(const short *addr, int pe);

int shmem_int_g(const int *addr, int pe);

long shmem_long_g(const long *addr, int pe);

long long shmem_longlong_g(const long long *addr, int pe);

float shmem_float_g(const float *addr, int pe);

double shmem_double_g(const double *addr, int pe);

long shmem_longdouble_g(const long double *addr, int pe);

💜 DESCRIPTION 💜

These routines provide a very low latency get capability for single elements of most basic types. No cap, that’s the official description — very low latency, single elements, most basic types. Slay ✨

The arguments are as follows:

• addr — the remotely accessible array element or scalar data object which will receive the data on the remote PE.
• pe — the number of the remote PE.

🦋 SEE ALSO 🦋

• intro_shmem(3)
• shmem_get(3)

go give these a read, bestie 🫶
