************ Synthetic traffic with slim fly network model **********- traffic patterns supported: uniform random, and worst-case traffic. - (1) Uniform random traffic: sends messages to a randomly selected destination node. This traffic pattern is uniformly distributed throughout the network and gives a better performance with minimal routing as compared to non-minimal or adaptive routing. - (2) Worst-case traffic: simulates an application that is communicating in a manner that fully saturates links in the network and thus creates a bottleneck for minimal routing. In this workload, each compute node in a router, R1, will communicate to a node within a paired router that is the maximum two hops away. Another pair of routers that share the same middle link with the previous pair of routers will be established to fully saturate that center link. This setup of network communication puts a worst-case burden on the link between routers 2 and 3 as 4p nodes are creating 2p data flows. With all nodes paired in this configuration, congestion quickly builds up for all nodes in the system and limits maximum throughput to 1/2p.HOW TO RUN:ROSS optimistic mode:mpirun -n 4 src/network-workloads/model-net-synthetic-slimfly --sync=3 --traffic=1 --load=0.95 -- ../../jenkins/codes/src/network-workloads/conf/modelnet-synthetic-slimfly-min.confROSS serial mode:./src/network-workloads/model-net-synthetic-slimfly --sync=1 --traffic=1 --load=0.95 -- ../../jenkins/codes/src/network-workloads/conf/modelnet-synthetic-slimfly-min.confoptions:load: percentage of link bandwidth each compute node is to utilize.
