Optimizing Strong-Scaling HPC Apps with DGX-2 & NVSwitch
Abstract:

NVSwitch on the DGX-2 is a super crossbar switch which greatly increases the application performance in several ways. First, it increases the problem size capacity traditionally limited by a single GPU's memory to the aggregate DGX-2 GPU memory of 512 GB. Second, NUMA-effects of traditional multi-GPU servers are greatly reduced, growing memory bandwidth with the number of GPUs. Finally, ease-of-use is simplified as apps written for a smaller number of GPUs can now be more easily ported with the large memory space.
