ABSTRACT
New 3D-XPoint™ technology, developed by Intel and Micron, promises to deliver high-density, lower-cost, non-volatile storage with DRAM-like performance characteristics. This paper presents a detailed empirical evaluation of Intel's Optane DC Persistent Memory solution that provides 3D-XPoint NV-DIMMs, which are directly attached to the memory bus. We evaluate general performance through a set of micro-benchmarks and also evaluate application-specific performance through measurement of a production bioinformatics workload (genome K-mer analysis). This is a memory-intensive workload that does not scale-out well with conventional data-partitioning and therefore directly benefits from increased main memory capacity. Thus, for this workload, 3D-Xpoint is key to enabling previously unattainable results. We compare performance with existing DRAM memory, evaluate different modes of operation and examine multiple integration approaches.

Phase-Change Technology and the Future of Main Memory
Phase-change memory may enable continued scaling of main memories, but PCM has higher access latencies, incurs higher power costs, and wears out more quickly than DRAM. This article discusses how to mitigate these limitations through buffer sizing, row ...
