Roadrunner Architecture and System Configuration
Roadrunner is a cluster of 64 individual
computing nodes, each with 2 CPUs per node, for a total of 128 processors.
A high-speed, low latency Myrinet network interconnects the 64 nodes,
and a Fast Ethernet network connects the cluster to file servers and the
Internet. Login access is provided via an additional four nodes.
Architecture and configuration details can be found in the tables below.
