DESCRIPTIONThese routines transfer nelems elements of the data object at address source on the calling PE, to the data object at address target on the remote PE pe. These routines start the remote transfer and may return before the data is delivered to the remote PE. The delivery of data into the data object on the destination PE from different put calls may occur in any order. Because of this, two successive put operations may deliver data out of order unless a call to shmem_fence(3) is introduced between the two calls. The arguments are as follows: target Data object to be updated on the remote PE. This data object must be remotely accessible. source Data object containing the data to be copied. len Number of elements in the target and source arrays. len must be of type integer. If you are using Fortran, it must be a constant, variable, or array element of default integer type. pe PE number of the remote PE. pe must be of type integer. If you are using Fortran, it must be a constant, variable, or array element of default integer type. The target and source data objects must conform to certain typing constraints, which are as follows: shmem_putmem: Fortran: Any noncharacter type. C: Any data type. len is scaled in bytes. shmem_put4, shmem_put32: Any noncharacter type that has a storage size equal to 32 bits. shmem_put8, shmem_put64: Any noncharacter type that has a storage size equal to 64 bits. shmem_put128: Any noncharacter type that has a storage size equal to 128 bits. shmem_short_put: Elements of type short. shmem_int_put: Elements of type int. shmem_long_put: Elements of type long. shmem_longlong_put: Elements of type long long. shmem_float_put: Elements of type float. shmem_double_put: Elements of type double. shmem_longdouble_put: Elements of type long double. SHMEM_CHARACTER_PUT: Elements of type character. len is the number of characters to transfer. The actual character lengths of the source and target variables are ignored. SHMEM_COMPLEX_PUT: Elements of type complex of default size. SHMEM_DOUBLE_PUT: (Fortran) Elements of type double precision. SHMEM_INTEGER_PUT: Elements of type integer. SHMEM_LOGICAL_PUT: Elements of type logical. SHMEM_REAL_PUT: Elements of type real. If you are using Fortran, data types must be of default size. For example, a real variable must be declared as REAL, REAL*4, or REAL(KIND=4).

EXAMPLESThe following shmem_put example is for C/C++ programs: #include <stdio.h> #include <mpp/shmem.h> main() { long source[10] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }; static long target[10]; shmem_init(); if (shmem_my_pe() == 0) { /* put 10 words into target on PE 1 */ shmem_long_put(target, source, 10, 1); } shmem_barrier_all(); /* sync sender and receiver */ if (shmem_my_pe() == 1) shmem_udcflush(); /* not required on Altix systems */ printf("target[0] on PE %d is %d\n", shmem_my_pe(), target[0]); }
