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**](#target) Array to be updated on the local PE. [**source**](#source) Array containing the data to be copied on the remote PE. [**tst**](#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**](#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**](#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) 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-iget32>, shmem\_iget4: Any noncharacter type that has a storage size**](#shmem_iget32) equal to 32 bits. [**shmem\_iget64 <#shmem-iget64>, shmem\_iget8: Any noncharacter type that has a storage size**](#shmem_iget64) equal to 64 bits. [**shmem\_iget128 <#shmem-iget128>: Any noncharacter type that has a storage size equal to**](#shmem_iget128) 128 bits. shmem\_short\_iget <#shmem-short-iget>: Elements of type short. shmem\_int\_iget <#shmem-int-iget>: Elements of type int. shmem\_long\_iget: Elements of type long. shmem\_longlong\_iget <#shmem-longlong-iget>: Elements of type long long. shmem\_float\_iget <#shmem-float-iget>: Elements of type float. shmem\_double\_iget <#shmem-double-iget>: Elements of type double. shmem\_longdouble\_iget <#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. shmem\_longdouble\_iget <#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. 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). # [NOTES](#NOTES) See [*intro\_shmem*(3)](/man/enterprise-packages/openmpi-cuda-13.2/intro_shmem.3) for a definition of the term remotely accessible. # [EXAMPLES](#EXAMPLES) The following simple example uses shmem\_logical\_iget in a Fortran program.
