| 7 | This short example presents how to describe computing resource location. |
---|
| 8 | Simulated architecture consists of data center with 2 racks named rack1 and rack2, respectively. |
---|
| 9 | Location of rack1 is defined using vector (4, 0, 2), while rack2 using vector (6, 0, 2) |
---|
| 10 | Rack1 contains 2 computing nodes - node11 and node12. Appropriate coordinates for node11 are (0, 0, 0) |
---|
| 11 | and for node12 (0, 1, 0). Rack2 contains 2 computing nodes named node21 and node22. Their location is defined as follows: |
---|
| 12 | (0, 0, 0) for node21 and (1, 0, 0) for node22. |
---|
| 13 | Using 3 coordinates allows to express location in various ways. It can be interpreted as a absolute placement in 3D, as well as the |
---|
| 14 | relative position according to the parent computing resource. Moreover, it is possible to define only the arrangement of |
---|
| 15 | the computing resources by increasing only the value of one coordinate. |
---|
| 16 | In the following example, racks location is defined using relative positions (with respect to the data center), while |
---|
| 17 | for nodes the order of appearance is specified (with additional direction in which the order tends |
---|
| 18 | (node12 is located after node11 and placed above it, while node22 is located on the right side of node21) |
---|
| 19 | It has to be stressed that simulator only stores the location parameters and does not process them. Hence, their interpretation should be done by user. |
