[codes-ross-users] how to use fattree static routing

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 at 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.
Try:
  dot / neato /home/peixin/fattree_simulation/routing_folder/topo.dot -Tpng
-o graph.png && evince graph.png
running simulate.py
Run ibsim...
Run opensm...
Check routing...
Scan fabric...
Stop ibsim/opensm...
Warning: 13526 already dead
Warning: 13520 already dead
Check the connectivity of the system...
mv: cannot stat
‘/home/peixin/fattree_simulation/routing_folder/ofedout/ibdiagnet.fdbs’: No
such file or directory

ERR: file /home/peixin/fattree_simulation/routing_folder/ibdiagnet.fdbs or

Thanks,
