High performance computers are typified by cluster machines constructed from multicore nodes and using high performance interconnects like Infiniband. Virtualizing such 'capacity computing' platforms implies the shared use of not only the nodes and node cores, but also of the cluster interconnect (e.g., Infiniband). This paper presents a detailed study of the implications of sharing these resources, using the Xen hypervisor to virtualize platform nodes and exploiting Infiniband's native hardware support for its simultaneous use by multiple virtual machines. Measurements are conducted with multiple VMs deployed per node, using modern techniques for hypervisor bypass for high performance network access, and evaluating the implications of resource sharing with different patterns of application behavior. Results indicate that multiple applications can share the cluster's multicore nodes without undue effects on the performance of Infiniband access and use. Higher degrees of sharing are possible with communication-conscious VM placement and scheduling.
