*** README file for fattree network model ***
1- Configuring CODES dragonfly network model
CODES dragonfly network model can be configured using the fattee config file (currently
located in codes/src/network-workloads/conf). Below is an example config file:
MODELNET_GRP
{
repetitions="12";
server="4";
modelnet_fattree="4";
fattree_switch="3";
}
PARAMS
{
....
ft_type="0";
num_levels="3";
switch_count="12";
switch_radix="8";
....
}
The first section, MODELNET_GRP specifies the LP types, number of LPs per type and their
configuration. In the above case, there are 12 repetitions of 4 server LPs, 4 fat tree
network node/terminal LPs and 3 fat tree switch LPs. Each repetition represents a leaf
level switch, nodes connected to it, and higher level switches that may be needed to
construct the fat-tree. The 'fattree_switch' parameter indicates there are 3 levels
to this fat tree and each repitition will have one switch from each level. This
configuration will create a total of (fattree_switch)*repetitions=12*3=36 switch LPs,
with 'fattree_switch' many switch LPs per level.
modelnet_fattree = radix of switch/2
fattree_switch = number of levels in the fattree (2 or 3)
ft_type:
0: Custom- ("Pruned" Fat Tree)
1: Standard Full Fat Tree
The Custom- ft_type is simply a pruned standard full fat tree. This layout type starts
with the standard full fat tree and then removes pods and adjusts L1-L2 switch connections
as needed to drop the total node/terminal count in the system. This approach still maintains
full bisection bandwidth. Knowing a full standard fat tree uses k pods of k/2 switches per
pod (k/2 L1 switches and k/2 L0 switches) and each switch in L0 connects to k/2 terminals,
then each pod connects to (k/2)*(k/2) terminals. Therefore, the number of pods needed to get
N-many terminals using the Custom- ft_type is Np = ceil(N/[(k/2)*(k/2)]). So the config file
should have "repetitions" = "switch_count" = Np*(k/2).
Supported PARAMS:
packet_size, chunk_size (ideally kept same)
modelnet_scheduler - NIC message scheduler
modelnet_order=( "fattree" );
router_delay : delay caused by switched in ns
num_levels : number of levels in the fattree (same as fattree_switch)
switch_count : number of leaf level switches (same as repetitions)
switch_radix : radix of the switches
vc_size : size of switch VCs in bytes
cn_vc_size : size of VC between NIC and switch in bytes
link_bandwidth, cn_bandwidth : in GB/s
routing : {adaptive, static}
2- Static Routing
If static routing is chosen, two more PARAMS must be provided:
routing_folder : folder that contain lft files generated using method described below.
dot_file : name used for dotfile generation in the method described below.
(dump_topo should be set to 0 or not set when during simulations)
To generate static routing tables, first do an "empty" run to dump the topology
of the fat-tree by setting the following PARAMS:
routing : static
routing_folder : folder to which topology files should be written
dot_file : prefix used for creating topology files inside the folder
dump_topo : 1
When dump_topo is set, the simulator dumps the topology inside the folder
specified by routing_folder and exits. Next, follow these steps created by Jens
to generate the routing tables stored as LFT files:
(you should replace $P_PATH with your path)
1. Install fall-in-place toolchain: (patch files can be found in src/util/patches folder of CODES):
wget http://htor.inf.ethz.ch/sec/fts.tgz
tar xzf fts.tgz
cd fault_tolerance_simulation/
rm 0001-*.patch 0002-*.patch 0003-*.patch 0004-*.patch 0005-*.patch
tar xzf $P_PATH/sar.patches.tgz
wget http://downloads.openfabrics.org/management/opensm-3.3.20.tar.gz
mv opensm-3.3.20.tar.gz opensm.tar.gz
wget http://downloads.openfabrics.org/ibutils/ibutils-1.5.7-0.2.gbd7e502.tar.gz
mv ibutils-1.5.7-0.2.gbd7e502.tar.gz ibutils.tar.gz
wget http://downloads.openfabrics.org/management/infiniband-diags-1.6.7.tar.gz
mv infiniband-diags-1.6.7.tar.gz infiniband-diags.tar.gz
wget https://www.openfabrics.org/downloads/management/libibmad-1.3.12.tar.gz
mv libibmad-1.3.12.tar.gz libibmad.tar.gz
wget https://www.openfabrics.org/downloads/management/libibumad-1.3.10.2.tar.gz
mv libibumad-1.3.10.2.tar.gz libibumad.tar.gz
patch -p1 < $P_PATH/fts.patch
./simuate.py -s
2. Add LFT creating scripts to the fall-in-place toolchain.
cd $HOME/simulation/scripts
patch -p1 < $P_PATH/lft.patch
chmod +x post_process_*
chmod +x create_static_lft.sh
3. Choose a routing algorithm which should be used by OpenSM
(possible options: updn, dnup, ftree, lash, dor, torus-2QoS, dfsssp, sssp)
export OSM_ROUTING="ftree"
~/simulation/scripts/create_static_lft.sh routing_folder dot_file
(here routing_folder and dot_file should be same as the one used during the run used to dump the topology)
Now, the routing table stored as LFT files should be in the routing_folder.
