18.2.127.1. 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)

18.2.127.2. DESCRIPTION

These routines provide a very low latency put 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.
value: The value to be transferred to addr on the remote PE.
pe: The number of the remote PE.

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.
