One-shot Garbage Collection for In-memory OLTP through Temporality-aware Version Storage
Anastasia Ailamaki, Periklis Chrysogelos, Angelos Christos Anadiotis, Syed Mohammad Aunn Raza
Most modern in-memory online transaction processing (OLTP) engines rely on multi-version concurrency control (MVCC) to provide data consistency guarantees in the presence of conflicting data accesses. MVCC improves concurrency by generating a new version o ...
ACM2023Rebooting Virtual Memory with Midgard
Virtual Memory (VM) is a critical programming abstraction that is widely used in various modern computing platforms. With the rise of datacenter computing and birth of planet-scale online services, the semantic and capacity requirements from memory have ev ...
EPFL2023A Large-Scale Characterization of How Readers Browse Wikipedia
Robert West, Tiziano Piccardi, Akhil Arora
Despite the importance and pervasiveness of Wikipedia as one of the largest platforms for open knowledge, surprisingly little is known about how people navigate its content when seeking information. To bridge this gap, we present the first systematic large ...
ASSOC COMPUTING MACHINERY2023Rethinking Software Runtimes for Disaggregated Memory
Disaggregated memory can address resource provisioning inefficiencies in current datacenters. Multiple software runtimes for disaggregated memory have been proposed in an attempt to make disaggregated memory practical. These systems rely on the virtual mem ...
ASSOC COMPUTING MACHINERY2021Access pattern based optimization of memory access
Anastasia Ailamaki, Georgios Psaropoulos
A method for optimizing memory access for database operations is provided. The method may include identifying an access pattern associated with a database operation. The access pattern may include data required to perform the database operation. One or mor ...
2020SPARTA: A Divide and Conquer Approach to Address Translation for Accelerators
Babak Falsafi, Javier Picorel Obando, Abhishek Bhattacharjee
Virtual memory (VM) is critical to the usability and programmability of hardware accelerators. Unfortunately, implementing accelerator VM efficiently is challenging because the area and power constraints make it difficult to employ the large multi-level TL ...
2020Gain-Cell Embedded DRAMs: Modeling and Design Space
Andreas Peter Burg, Adam Shmuel Teman, Robert Giterman, Andrea Bonetti
Among the different types of DRAMs, gain-cell embedded DRAM (GC-eDRAM) is a compact, low-power and CMOS-compatible alternative to conventional SRAM. GC-eDRAM achieves high memory density as it relies on a storage cell that can be implemented with as few as ...
IEEE2020Perovskite Flash Memory with a Single-Layer Nanofloating Gate
Mohammad Khaja Nazeeruddin, Peng Gao, Hobeom Kim
Here we use triple-cation metal-organic halide perovskite single crystals for the transistor channel of a flash memory device. Moreover, we design and demonstrate a 10 nm thick single-layer nanofloating gate. It consists of a ternary blend of two organic s ...
2020Prefetched Address Translation
Edouard Bugnion, Boris Robert Grot, Dmitrii Ustiugov
With explosive growth in dataset sizes and increasing machine memory capacities, per-application memory footprints are commonly reaching into hundreds of GBs. Such huge datasets pressure the TLB, resulting in frequent misses that must be resolved through a ...
ASSOC COMPUTING MACHINERY2019Timely and cost-efficient data exploration through adaptive tuning
Modern applications accumulate data at an exponentially increasing rate and traditional database systems struggle to keep up.
Decision support systems used in industry, rely heavily on data analysis, and require real-time responses irrespective of data siz ...
