Beowulf Setup – Network Hardware Design By: Jonathan Pingilley
Case Studies Network Design
Multiple Hardware Design • Using 1x64-port GbE
Design IV • Using switch meshing
Flat Neighborhood Networks • Uses multiple NICs per machine • Requires special routing • Using a generic algorithm: http://aggregate.org/FNN/ • Get from any machine to another in one hop • Doesn’t require managed switches
Switch-less Designs: 5 Node Ring • Each machine has two nic cards • ETH0 & ETH1 • route add -host 192.168.0.2 gw 192.168.0.1 • route add -host 192.168.0.5 gw 192.168.1.1 • route add -host 192.168.0.3 gw 192.168.0.1 • route add -host 192.168.0.4 gw 192.168.1.1
8 Node Hypercube • Each node has three NICs. • For each node we will have 3 direct connections
Final Thoughts • Switchless design has the potential to improve bisection width • Downside: latency • Not necessarily cheaper to build. • Direct connections can be used in place of switched designs. • Cluster Design Website: http://aggregate.org/CDR/
