SHMEM_LONG_G(3) Open MPI SHMEM_LONG_G(3)


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.

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.

The arguments are as follows:

The remotely accessible array element or scalar data object which will receive the data on the remote PE.
The number of the remote PE.
