18.2.118. shmem_long_g — Open MPI 5.0.10 documentation

# 18.2.118. shmem_long_g

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) - 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.

## 18.2.118.1. 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)

## 18.2.118.2. DESCRIPTION

These routines provide a very low latency get capability for single elements of most basic types.

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.
