Evaluating Networking Options for HPC & Cloud

InfiniBand (IB) and High-Speed Ethernet (HSE) interconnects are generating a lot of excitement towards building next generation scientific, enterprise and cloud computing systems. OpenFabrics stack is emerging to encapsulate both IB and Ethernet in a unified manner, and hardware technologies such as Virtual Protocol Interconnect (VPI), RDMA over Converged Enhanced Ethernet (RoCE) are converging the hardware solutions.

In this video recorded at Hot Interconnects 2012 in Santa Clara last week, Jerome Vienne from Ohio State University presents: Performance Analysis and Evaluation of InfiniBand FDR and 40GigE RoCE on HPC and Cloud Computing Systems.

We evaluate various high performance interconnects over the new PCIe Gen3 interface with HPC as well as cloud computing workloads. Our comprehensive analysis, done at different levels, provides a global scope of the impact these modern interconnects have on the performance of HPC applications and cloud computing middlewares. The results of our experiments show that the latest InfiniBand FDR interconnect gives the best performance for HPC as well as cloud computing applications.”
