* This program is an adaptation of examples found in the man pages

* of SGI’s SHMEM implementation.
|
||
*
|
||
* In this program, iput is used to select 5 elements from array source separated by
|
||
* a stride of 2 and write them to array target using a stride of 1.
|
||
*
|
||
* Given the array source = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }
|
||
* iput will select 5 elements from array source on PE 0, using a stride of 2:
|
||
*
|
||
* selected elements = { 1, 3, 5, 7, 9 }
|
||
*
|
||
* These elements will then be written to the array source on PE 1 using a stride of 1:
|
||
*
|
||
* target = { 1, 3, 5, 7, 9 }
