\- 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.
|
|
.SH SYNOPSIS
|
|
|
|
C or C++:
|
|
.Vb
|
|
#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);

.SH DESCRIPTION
|
|
|
|
These routines provide a very low latency put capability for single elements of most basic types.
|
|
.PP
|
|
The arguments are as follows:
|
|
.TP
|
|
addr
|
|
The remotely accessible array element or scalar data object which will receive the
|
|
data on the remote PE.
|
|
.TP
|
|
value
|
|
The value to be transferred to addr on the remote PE.
|
|
.TP
|
|
pe
|
|
The number of the remote PE.
|
|
.PP
|
|
As with \fIshmem_put\fP(3),
|
|
these functions start the remote transfer and may return before
|
|
the data is delivered to the remote PE. Use \fIshmem_quiet\fP(3)
|
|
to force completion of all
|
|
remote PUT transfers.
