Field Halo Test Description

Test Description: Halo operation with an Array interface

Test Configuration

• Test Programming Language: Fortran90
• Number of PETs: 12
• Communications Method: MPI

Sections

The main program of the test application consists of the following sections.

• Create
• Initialize
• Run
• Finalize
• Destroy

Create

• Creates a 3x4 DELayout

9	10	11
6	7	8
3	4	5
0	1	2

• Creates a Component named "System Test #70385"

Initialize

• Creates a horizontal 30x36 global Grid, distributed over DELayout with a halo of 2 in each direction.
• Allocates an Array with 14x13 cells on each DE (10x9 plus the halo).
• Sets the initial value over the entire Array to -1
• Sets the initial value over the the exclusive domain to the DE identifier.
• Creates a Field using the Grids and Arrays

Run

• Does a halo operation on the Field

Finalize

• Prints out the results of the halo operation

Destroy

• Deallocates memory for all the created objects by calling destroy subroutines for the Component, Field, Grid Arrays, and DELayout.
