Hi CODES,

When I run the command in README.fattree.txt, I cannot finish creating static routing table. The third step cannot be finished as follows:

How to create fat-tree static routing table with 36-ports switch?

Thanks, Peixin

Hi, I still cannot create the routing table. Here is what I did and the error report: 1: I do the "empty" run to dump the topology and only get the file: fattree.dot.0, which is in attachment 2: When I run ./simulate.py -s, I get the following result: patching file Makefile.am patching file scripts/scheduler-sar-interface.py Step 1... Step 2... Step 3... Step 4... Step 5... Step 6... sed: can't read /home/peixin/simulation/ofed/bin/ibdiagnet: No such file or directory ...... skipping omnet install ..... Step 9... 3. Finally I run ~/simulation/scripts/create_static_lft.sh routing_folder dot_file, and get the following result: peixin@peixin:~/simulation/scripts$ ~/simulation/scripts/create_static_lft.sh /home/peixin/fattree_simulation/routing_folder fattree running createIBNet.py Selected configuration: Output: /home/peixin/fattree_simulation/routing_folder/topo.net Topology: DOT Number of endpoints: 8 Number of ports per endpoints: 1 Number of switches: 4 Number of ports per switch: 4 Dimensions for Mesh/Torus: -1, -1, -1 k-ary-n Tree: -1 -ary- -1 Kautz K(b,n): K(-1; -1) XGFT(h,m,w): XGFT(-1; -1; -1) Dragonfly(a,p,h) : Dragonfly(-1, -1, -1) with -1 groups Cascade(a,p,h,g) : Cascade(96, 8, 10) with -1 groups Tofu(d1,d2,d3) : Tofu(-1, -1, -1) with -1 groups This program also writes an dot-file to plot the graph with Graphviz.

routing_folder and dot_file are keywords/parameters in the config file whose values were chosen by you during the topology dump run. It is described in the second step "2- Static Routing”.

So what is the routing_folder and dot_file? Is the following correct?

routing_folder: mkdir routing_folder dot_file: python simulate.py createIBNet -t XGFT -xh 3 -xm 18,18,36 -xw 1,18,18 -sp 36 (get 2 files: net.dot and net.txt)
