1084 It supports not just K-ary-N-Trees, by handling for non-constant K,
1085 cases where not all leafs (CAs) are present, any CBB ratio.
1086 As in UPDN, fat-tree also prevents credit-loop-deadlocks.
1088 If the root guid file is not provided ('-a' or '--root_guid_file' options),
1089 the topology has to be pure fat-tree that complies with the following rules:
1090 - Tree rank should be between two and eight (inclusively)
1091 - Switches of the same rank should have the same number
1092 of UP-going port groups*, unless they are root switches,
1093 in which case the shouldn't have UP-going ports at all.
1094 - Switches of the same rank should have the same number
1095 of DOWN-going port groups, unless they are leaf switches.
1096 - Switches of the same rank should have the same number
1097 of ports in each UP-going port group.
1098 - Switches of the same rank should have the same number
1099 of ports in each DOWN-going port group.
1100 - All the CAs have to be at the same tree level (rank).

1104 - Tree rank should be between two and eight (inclusively)

1120 ratio, the routing will not be as balanced as in case of integer CBB ratio.
1125 pure and symmetrical fat-tree, the more optimal the routing will be.
1127 The algorithm also dumps compute node ordering file (opensm-ftree-ca-order.dump)
