Gutenberg: Taming Latency-Critical Cloud Services with Near-Data-Processing

Latency-critical cloud services place growing pressure on memory while requiring isolation, fairness, and predictable QoS. Near-data processing (NDP) reduces data movement by executing requests close to memory, and prior systems further improve locality through caching and replication. However, writes make replica main...

CrocSort: Resource-Efficient, Skew-Resilient Parallel External Merge Sort

CrocSort is presented, a byte-balanced parallel external merge sort with configurable memory and per-phase thread settings with practical resource-configuration rules for selecting these settings from input size, memory budget, and thread cap.

Borges: A Low-Latency Distributed Shared Log on a CXL Memory/SSD Hybrid

Fault-tolerant, distributed shared logs are a useful substrate for distributed applications, but existing designs coordinate shard servers, sequencers, and replicas over the network, so append and replay latency is dominated by message exchange. We present Borges, to our knowledge the first fault-tolerant shared log wh...

Breaking the Single-Entry Bottleneck: Dynamic Write Routing for Heterogeneous Key-Value Stores

Modern heterogeneous storage no longer follows a simple fast/slow hierarchy. Byte-addressable NVM provides fine-grained, low-latency persistence, whereas NVMe SSDs deliver high bandwidth under deep queues and offer greater capacity. Most LSM-tree key-value stores, however, send every foreground write through a designat...

Don't let your Memory defy you: Fragmentation-Aware Serverless Allocation with Elastic Memory Locality

Serverless platforms commonly rely on bundled, memory-centric configurations, where CPU capacity follows the specified memory size. Resource decoupling reduces this waste, but can create external fragmentation by producing diverse CPU-memory shapes that leave residual capacity stranded across nodes. Memory disaggregati...
