DESCRIPTION

The strided get routines retrieve array data available at address source on remote PE (pe). The elements
of the source array are separated by a stride sst. Once the data is received, it is stored at the local
memory address target, separated by stride tst. The routines return when the data has been copied into
the local target array.

The arguments are as follows:

target Array to be updated on the local PE.

source Array containing the data to be copied on the remote PE.

tst The stride between consecutive elements of the target array. The stride is scaled by the element
size of the target array. A value of 1 indicates contiguous data. tst must be of type integer. If
you are calling from Fortran, it must be a default integer value.

sst The stride between consecutive elements of the source array. The stride is scaled by the element
size of the source array. A value of 1 indicates contiguous data. sst must be of type integer. If
you are calling from Fortran, it must be a default integer value.

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 typing constraints, which are as follows:

shmem_iget32, shmem_iget4: Any noncharacter type that has a storage size
equal to 32 bits.

shmem_iget64, shmem_iget8: Any noncharacter type that has a storage size
equal to 64 bits.

shmem_iget128: Any noncharacter type that has a storage size equal to
128 bits.

shmem_short_iget: Elements of type short.

shmem_int_iget: Elements of type int.

shmem_long_iget: Elements of type long.

shmem_longlong_iget: Elements of type long long.

shmem_float_iget: Elements of type float.

shmem_double_iget: Elements of type double.

shmem_longdouble_iget: Elements of type long double.

SHMEM_COMPLEX_IGET: Elements of type complex of default size.

SHMEM_DOUBLE_IGET: (Fortran) Elements of type double precision.

SHMEM_INTEGER_IGET: Elements of type integer.

SHMEM_LOGICAL_IGET: Elements of type logical.

SHMEM_REAL_IGET: Elements of type real.
