Benefits of Multi-rail Cluster Architectures for GPU-based Nodes

Craig Tierney from NVIDIA gave this talk at the MVAPICH User Group meeting. “As high performance computing moves toward GPU-accelerated architectures, single node application performance can be between 3x and 75x faster than the CPUs alone. Performance increases of this size will require increases in network bandwidth and message rate to prevent the network from becoming the bottleneck in scalability. In this talk, we will present results from NVLink enabled systems connected via quad-rail EDR Infiniband.”

Challenges and Opportunities for HPC Interconnects and MPI

“This talk will reflect on prior analysis of the challenges facing high-performance interconnect technologies intended to support extreme-scale scientific computing systems, how some of these challenges have been addressed, and what new challenges lay ahead. Many of these challenges can be attributed to the complexity created by hardware diversity, which has a direct impact on interconnect technology, but new challenges are also arising indirectly as reactions to other aspects of high-performance computing, such as alternative parallel programming models and more complex system usage models.”
