how to use fattree static routing
by Peixin Qiao 15 Mar '17

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: peixin@peixin:~/simulation/scripts/routing_folder$ ls net.dot net.txt peixin@peixin:~/simulation/scripts/routing_folder$ cd .. peixin@peixin:~/simulation/scripts$ ~/simulation/scripts/create_static_lft.sh /home/peixin/simulation/scripts/routing_folder/ net dot file already exists. running createIBNet.py Selected configuration: Output: /home/peixin/simulation/scripts/routing_folder/topo.net Topology: XGFT Number of endpoints: 8 Number of ports per endpoints: 1 Number of switches: 4 Number of ports per switch: 36 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(3; 18,18,36; 1,18,18) 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.

Simulation ends with events unprocessed
by Jian Peng 06 Mar '17

Hi, I'm running some experiments on Dragonfly with CODES 5.0.2. Sometimes they end up with unsent messages remaining in terminals and routers. I think the reason is the events that carry these messages are not handled. I looked through my debugging information and confirmed it. So, why does ROSS end when there are still events unprocessed? I'm running a sequential simulation. Thanks. [image: Inline image 1]

Hi All, Most of you might be already aware but we have a CODES wiki setup that provides details on the interconnect models, workload generators, best practices on model development, collective translation and much more. Please feel free to visit and share your feedback. https://xgitlab.cels.anl.gov/codes/codes/wikis/home Regards, Misbah
