Sharing Data and Work Across Concurrent Analytical Queries

Anastasia Ailamaki, Manoussos Gavriil Athanassoulis, Iraklis Psaroudakis

Today's data deluge enables organizations to collect massive data, and analyze it with an ever-increasing number of concurrent queries. Traditional data warehouses (DW) face a challenging problem in executing this task, due to their query-centric model: ea ...

Design Methods for Parallel Hardware Implementation of Multimedia Iterative Algorithms

David Atienza Alonso, Ivan Beretta, Alessandro Antonio Nacci

Traditionally, parallel implementations of multimedia algorithms are carried out manually, since the automation of this task is very difficult due to the complex dependencies that generally exist between different elements of the data set. Moreover, there ...

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 ...

SLICC: Self-Assembly of Instruction Cache Collectives for OLTP Workloads

Anastasia Ailamaki, Pinar Tözün

Online transaction processing (OLTP) is at the core of many data center applications. OLTP workloads are known to have large instruction footprints that foil existing L1 instruction caches resulting in poor overall performance. Prefetching can reduce the i ...
