Deep Learning/AI Lifecycle with Dell EMC and bitfusion Bhavesh Patel Dell EMC Server Advanced Engineering Mazhar Memon CTO Bitfusion
Abstract This talk gives an overview of the end to end application life cycle of deep learning in the enterprise along with numerous use cases and summarizes studies done by Bitfusion and Dell on a high performance heterogeneous elastic rack of DellEMC PowerEdge C4130s with Nvidia GPUs. Some of the use cases that will be talked about in detail will be ability to bring on-demand GPU acceleration beyond the rack across the enterprise with easy attachable elastic GPUs for deep learning development, as well as the creation of a cost effective software defined high performance elastic multi-GPU system combining multiple DellEMC C4130 servers at runtime for deep learning training.
