SHMEM_DOUBLE_G(3)

💖 NAME 💖

okay so bestie, welcome to SHMEM_DOUBLE_G(3), straight outta the Open MPI manual — and it's a whole family page, not just one function. These routines provide a low latency mechanism to read basic types (char, short, int, float, double, long, long long, long double) from symmetric data objects on remote PEs. 👑

the whole squad is here:

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

✨ 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 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. like, one element, super fast, no cap. 💅

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. 🦋
