Establishing a base of trust with performance counters for enterprise workloads

Understanding the performance of large, complex enterprise-class applications is an important, yet nontrivial task. Methods using hardware performance counters, such as profiling through event-based sampling, are often favored over instrumentation for anal ...

Exploiting NVM in Large-scale Graph Analytics

Willy Zwaenepoel, Jasmina Malicevic

Data center applications like graph analytics require servers with ever larger memory capacities. DRAM scaling, how- ever, is not able to match the increasing demands for ca- pacity. Emerging byte-addressable, non-volatile memory technologies (NVM) offer a ...

Execution Trace Graph Based Multi-criteria Partitioning of Stream Programs

Marco Mattavelli, Simone Casale Brunet, Endri Bezati, Malgorzata Maria Michalska

One of the problems proven to be NP-hard in the field of many-core architectures is the partitioning of stream programs. In order to maximize the execution parallelism and obtain the maximal data throughput for a streaming application it is essential to fi ...

Shared Frontend for Manycore Server Processors

Ilknur Cansu Kaynak

Instruction-supplymechanisms, namely the branch predictors and instruction prefetchers, exploit recurring control flow in an application to predict the applicationâs future control flow and provide the core with a useful instruction stream to execute in ...

An Adjoint Approach for Stabilizing the Parareal Method

Jan Sickmann Hesthaven, Allan Svejstrup Nielsen, Yvon Maday

The parareal algorithm seeks to extract parallelism in the time-integration direction of time-dependent differential equations. While it has been applied with success to a wide range of problems, it suffers from some stability issues when applied to non-di ...

Transactions Chasing Scalability and Instruction Locality on Multicores

Pinar Tözün

For several decades, online transaction processing (OLTP) has been one of the main server applications that drives innovations in the data management ecosystem, and in turn the database and computer architecture communities. Recent hardware trends oblige s ...

Eliminating unscalable communication in transaction processing

Anastasia Ailamaki, Frederick Ryan Johnson, Ippokratis Pandis

Multicore hardware demands software parallelism. Transaction processing workloads typically exhibit high concurrency, and, thus, provide ample opportunities for parallel execution. Unfortunately, because of the characteristics of the application, transacti ...

Manual Parallelization Versus State-of-the-Art Parallelization Techniques: The SPEC CPU2006 as a Case Study

Aleksandar Vitorovic

Being multiprocessors (both on-chip and/or off-chip), modern computer systems can automatically exploit the benefits of parallel programs, but their resources remain underutilized in executing still-Prevailing sequential applications. An obvious solution i ...

High-level dataflow design of signal processing systems for reconfigurable and multicore heterogeneous platforms

Marco Mattavelli, Endri Bezati, Ghislain Roquier, Richard Thavot

The potential computational power of today multicore processors has drastically improved compared to the single processor architecture. Since the trend of increasing the processor frequency is almost over, the competition for increased performance has move ...
