RecSSD: Near Data Processing for Solid State Drive Based Recommendation Inference

Wilkening, Mark, Gupta, Udit, Hsia, Samuel et al.

Understand

Neural personalized recommendation models are used across a wide variety of datacenter applications including search, social media, and entertainment.

  • State-of-the-art models comprise large embedding tables that have billions of parameters requiring large memory capacities.
  • Unfortunately, large and fast DRAM-based memories levy high infrastructure costs.
  • Conventional SSD-based storage solutions offer an order of magnitude larger capacity, but have worse read latency and bandwidth, degrading inference performance.
