HetExchange: Encapsulating heterogeneous CPU-GPU parallelism in JIT compiled engines

Anastasia Ailamaki, Periklis Chrysogelos, Manolis Karpathiotakis, Raja Appuswamy

Modern server hardware is increasingly heterogeneous as hardware accelerators, such as GPUs, are used together with multicore CPUs to meet the computational demands of modern data analytics workloads. Unfortunately, query parallelization techniques used by ...

Leveraging Hardware Message Passing for Efficient Thread Synchronization

André Schiper, Thomas Ropars, Darko Petrovic

As the level of parallelism in manycore processors keeps increasing, providing efficient mechanisms for thread synchronization in concurrent programs is becoming a major concern. On cache-coherent shared-memory processors, synchronization efficiency is ult ...

Virtual Ways: Low-Cost Coherence for Instruction Set Extensions with Architecturally Visible Storage

Edoardo Charbon, Paolo Ienne, Ties Jan Henderikus Kluter, Samuel Burri, Philip Brisk

Instruction set extensions (ISEs) improve the performance and energy consumption of application-specific processors. ISEs can use architecturally visible storage (AVS), localized compiler-controlled memories, to provide higher I/O bandwidth than reading da ...

Multi-Grain Coherence Directory

Babak Falsafi

Conventional directory coherence operates at the finest granularity possible, that of a cache block. While simple, this organization fails to exploit frequent application behavior: at any given point in time, large, continuous chunks of memory are often ac ...

MPSoC Design using Application-Specific Architecturally Visible Communication

Edoardo Charbon, Paolo Ienne, Ties Jan Henderikus Kluter, Philip Brisk

This paper advocates the placement of Architecturally Visible Communication (AVC) buffers between adjacent cores in MPSoCs to provide high-throughput communication for streaming applications. Producer/consumer relationships map poorly onto cache-based MPSo ...

Mechanisms for store-wait-free multiprocessors

Anastasia Ailamaki, Babak Falsafi

Store misses cause significant delays in shared-memory multiprocessors because of limited store buffering and ordering constraints required for proper synchronization. Today, programmers must choose from a spectrum of memory consistency models that reduce ...

The Granularity of Soft-Error Containment in Shared-Memory Multiprocessors

Babak Falsafi

Concerns over rising soft-error rates in processor logic has led to numerous proposals for error tolerance mechanisms. In this paper, we examine the role of soft-error containment in a shared memory multiprocessor. We study a range of design alternatives b ...

Reunion: Complexity-effective multicore redundancy

Babak Falsafi

To protect processor logic from soft errors, multicore redundant architectures execute two copies of a program on separate cores of a chip multiprocessor (CMP). Maintaining identical instruction streams is challenging because redundant cores operate indepe ...
