In-Data vs. Near-Data Processing: The Case for Resistive CAM Processing in Storage
Abstract
Near-data in-storage processing research has been gaining momentum in recent years. Typical processing-in-storage architecture places a single or several processing cores inside the storage and allows data processing without transferring it to the host CPU. Since this
approach replicates von Neumann architecture inside storage, it is exposed to the problems faced by von Neumann architectures, especially the bandwidth wall. We present a novel processing-in-storage system based on Resistive Content Addressable Memory (RCAM). RCAM functions simultaneously as a storage and a massively parallel associative processor. RCAM processing-in-storage resolves the bandwidth wall faced by conventional processing-in-storage architectures by keeping the computing inside the storage arrays, thus implementing in-data, rather than near-data, processing. We show that RCAM based processing-in-storage architecture may outperform existing in-storage designs and accelerator based designs. RCAM processing-in-storage implementation of K-means achieves speedup of 4.6—68 relative to CPU, GPU and FPGA based solutions. For K-Nearest Neighbors, RCAM processing-in-storage achieves speedup of 17.9—17,470 and for Smith-Waterman sequence alignment it reaches speedup of almost 5 over a GPU cluster based solution.
BIO
Leonid Yavits received his MSc and PhD in Electrical Engineering from the Technion. After graduating, he co-founded VisionTech where he co-designed the world's first single chip MPEG2 codec. Following VisionTech’s acquisition by Broadcom, he managed Broadcom Israel R&D and co-developed a number of video compression products. Later Leonid co-founded Horizon Semiconductors where he co-designed a Set Top Box-on-chip for cable and satellite TV. Horizon's chip was among world's earliest heterogeneous MPSoC.
