Abstract
The performance of modern recommendation models is limited because of the memory bandwidth-hungry embedding layer reductions. A novel hybrid memory system is presented with DRAM and RRAM with PIM capability. The performance of traditional RRAM PIM is limited by the latency of bit-serial computation. The hybrid memory system presents a comprehensive optimization approach that includes access-pattern aware mapping, compute complexity reduction, and selective PIM reduction to offset this computation latency. An evaluation shows that the hybrid memory system offers significant performance, energy, and EDP improvement of 2.6×, 1.7×, and 4.4×, on average, compared to a CPU baseline.
