shmem_char_p(3), shmem_float_p(3), shmem_int_p(3), shmem_long_p(3),
shmem_short_p(3), shmem_longlong_p(3), shmem_longdouble_p(3) - These routines
provide a low latency mechanism to write basic types (char, short, int,
float, double, long, long long, long double) to symmetric data objects
on remote PEs.
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);
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.
