STREX: Boosting Instruction Cache Reuse in OLTP Workloads Through Stratified Transaction Execution

Anastasia Ailamaki, Pinar Tözün, Xin Tong

Online transaction processing (OLTP) workload performance suffers from instruction stalls; the instruction footprint of a typical transaction exceeds by far the capacity of an L1 cache, leading to ongoing cache thrashing. Several proposed techniques remove ...

Synchronizing Code Execution on Ultra-Low-Power Embedded Multi-Channel Signal Analysis Platforms

David Atienza Alonso, Andreas Peter Burg, Giovanni Ansaloni, Ruben Braojos Lopez, Jeremy Hugues-Felix Constantin, Ahmed Yasir Dogan

Embedded biosignal analysis involves a considerable amount of parallel computations, which can be exploited by employing low-voltage and ultra-low-power (ULP) parallel computing architectures. By allowing data and instruction broadcasting, single instructi ...

A High-Level Synthesis Flow for the Implementation of Iterative Stencil Loop Algorithms on FPGA Devices

David Atienza Alonso, Ivan Beretta, Alessandro Antonio Nacci

The automatic generation of hardware implementations for a given algorithm is generally a difficult task, especially when data dependencies span across multiple iterations such as in iterative stencil loops (ISLs). In this paper, we introduce an automatic ...

The Bionic DBMS is Coming, but What Will It Look Like?

Frederick Ryan Johnson, Ippokratis Pandis

Software has always ruled database engines, and commodity processors riding Moore's Law doomed database machines of the 1980s from the start. However, today's hardware landscape is very different, and moving in directions that make database machines increa ...

Reducing OLTP Instruction Misses With Thread Migration

Anastasia Ailamaki, Pinar Tözün

During an instruction miss a processor is unable to fetch instructions. The more frequent instruction misses are the less able a modern processor is to find useful work to do and thus performance suffers. Online transaction processing (OLTP) suffers from h ...

Multi-Core Architecture Design for Ultra-Low-Power Wearable Health Monitoring Systems

David Atienza Alonso, Andreas Peter Burg, Jeremy Hugues-Felix Constantin, Martino Ruggiero, Ahmed Yasir Dogan

Personal health monitoring systems can offer a cost-effective solution for human healthcare. To extend the lifetime of health monitoring systems, we propose a near-threshold ultra-low- power multi-core architecture featuring low-power cores, yet capable of ...

Fine-grained Parallel Traversals of Irregular Data Structures

James Richard Larus

Fine-grain data parallelism is increasingly common in mainstream processors in the form of long vectors and on-chip GPUs. This paper develops compiler and runtime support to exploit such data parallelism for non-numeric, non-graphic, irregular parallel tas ...

SQPR: Stream query planning with reuse

Daniel Kuhn, Wolfram Wiesemann

When users submit new queries to a distributed stream processing system (DSPS), a query planner must allocate physical resources, such as CPU cores, memory and network bandwidth, from a set of hosts to queries. Allocation decisions must provide the correct ...
