This short example presents how to describe computing resource location. Simulated architecture consist of data center with 2 racks named rack1 and rack2, respectively. Location of rack1 is defined using vector (4, 0, 2), while rack2 according to vector (6, 0, 2) Rack1 contains 2 computing nodes - node11 and node12. Appropriate coordinates for node11 are (0, 0, 0) and for node12 (0, 1, 0). Rack2 contains 2 computing nodes named node21 and node22. Their location is defined as follows: (0, 0, 0) for node21 and (1, 0, 0) for node22. Using 3 coordinates allows to express location in various ways. It can be interpreted as a absolute placement in 3D, as well as the relative position according to the precedent computing resource. Moreover, it is possible to define only the arrangement of the computing resources by increasing only the value of one coordinate. In the following example, racks location is defined using relative positions (with respect to the data center), while for nodes the order of appearance is specified (with additional direction in which the order tends (node12 is located after node11 and placed above it, while node22 is located on the right side of node21) 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. 4 0 2 0 0 0 0 1 0 6 0 2 0 0 0 1 0 0 FCFSLocalSchedulingPlugin dataCenter
