Caching All Plans with Just One Optimizer Call

Anastasia Ailamaki, Ioannis Alagiannis, Debabrata Dash, Cristina Ileana Maier

Modern database management systems (DBMS) answer a multitude of complex queries on increasingly larger datasets. Given the complexities of the queries and the numerous design features, manual design is no longer an option. Instead, automatically designing ...

Reactive NUCA: Near-Optimal Block Placement and Replication in Distributed Caches

Anastasia Ailamaki, Babak Falsafi, Michael Ferdman

Increases in on-chip communication delay and the large working sets of server and scientific workloads complicate the design of the on-chip last- level cache for multicore processors. The large working sets favor a shared cache design that maximizes the ag ...

Dynamic Resource Allocation for Database Servers Running on Virtual Storage

Adrian Daniel Popescu, Daniel Lupei, Jin Chen

We introduce a novel multi-resource allocator to dynamically allocate resources for database servers running on virtual storage. Multi-resource allocation involves proportioning the database and storage server caches, and the storage bandwidth between appl ...

Temporal instruction fetch streaming

Anastasia Ailamaki, Babak Falsafi, Michael Ferdman

L1 instruction-cache misses pose a critical performance bottleneck in commercial server workloads. Cache access latency constraints preclude L1 instruction caches large enough to capture the application, library, and OS instruction working sets of these wo ...

Miss Rate Prediction across Program Inputs and Cache Configurations

Chen Ding

Improving cache performance requires understanding cache behavior. However, measuring cache performance for one or two data input sets provides little insight into how cache behavior varies across all data input sets and all cache configurations. This pape ...

Improving instruction cache performance in OLTP

Anastasia Ailamaki

Instruction-cache misses account for up to 40%; of execution time in online transaction processing (OLTP) database workloads. In contrast to data cache misses, instruction misses cannot be overlapped with out-of-order execution. Chip design limitations do ...

Using Code Transformation for Consistent and Transparent Caching of Dynamic Web Content

Willy Zwaenepoel, Sumit Mittal

We present a consistent and transparent caching system for dynamic web pages produced by a server-side application using a back-end database. Cached pages always reflect current database values. No intervention from the programmer is necessary to implement ...

Near-optimal precharging in high-performance nanoscale CMOS caches

Babak Falsafi

High-performance caches statically pull up the bit-lines in all cache subarrays to optimize cache access latency. Unfortunately, such architecture results in a significant waste of energy in nanoscale CMOS implementations due to high leakage and bitline di ...

IO-Lite: a unified I/O buffering and caching system

Willy Zwaenepoel

This article presents the design, implementation, and evaluation of IO -Lite, a unified I/O buffering and caching system for general-purpose operating systems. IO-Lite unifies all buffering and caching in the system, to the extent permitted by the hardware ...
