ParaLog: enabling and accelerating online parallel monitoring of multithreaded applications

Babak Falsafi, Evangelos Vlachos

Instruction-grain lifeguards monitor the events of a running application at the level of individual instructions in order to identify and help mitigate application bugs and security exploits. Because such lifeguards impose a 10-100X slowdown on existing pl ...

Exploring Programming Model-driven QoS Support for NoC-based Platforms

Giovanni De Micheli, Luca Benini, Federico Angiolini, Jaime Joven Murillo

Networks-on-Chip (NoCs) are being increasingly considered as a central enabling technology to communication-centric designs as more and more IP blocks are integrated on the same SoC. Embedded applications, in turn, are becoming extremely sophisticated, and ...

A Novel Parallel QR Algorithm For Hybrid Distributed Memory HPC Systems

Daniel Kressner, Bo Kågström

A novel variant of the parallel QR algorithm for solving dense nonsymmetric eigenvalue problems on hybrid distributed high performance computing systems is presented. For this purpose, we introduce the concept of multiwindow bulge chain chasing and paralle ...

Fast Access to Distributed Atomic Memory

Rachid Guerraoui, Marko Vukolic, Ron Levy, Partha Dutta

We study eﬃcient and robust implementations of an atomic read-write data structure over an asynchronous distributed message-passing system made of reader and writer processes, as well as a number of servers implementing the data structure. We determine the ...

JErlang: Erlang with Joins

Hubert Plociniczak

ERLANG is an industrially successful functional language that uses the Actor model for concurrency. It supports the message-passing paradigm by providing pattern-matching over received messages. Unfortunately coding synchronisation between multiple process ...

A Generic Parallel Collection Framework

Martin Odersky, Tiark Rompf, Aleksandar Prokopec

Most applications manipulate structured data. Modern languages and platforms provide collection frameworks with basic data structures like lists, hashtables and trees. These data structures come with a range of predefined operations which include sorting, ...

A hardware-software codesign framework for cellular computing

Pierre-André Mudry

Until recently, the ever-increasing demand of computing power has been met on one hand by increasing the operating frequency of processors and on the other hand by designing architectures capable of exploiting parallelism at the instruction level through h ...

Performance prediction and race detection in message-passing parallel applications

Basile Schäli

The combination of low cost clusters and multicore processors lowers the barrier for accessing massive amounts of computing power. As computational sciences advance, the use of in silico simulations to complement in vivo experiments promises parallel progr ...

Inducing Thermal-Awareness in Multicore Systems Using Networks-on-Chip

David Atienza Alonso

Technology scaling imposes an ever increasing temperature stress on digital circuit design due to transistor density, especially on highly integrated systems, such as Multi- Processor Systems-on-Chip (MPSoCs). Therefore, temperature-aware design is mandato ...

Method to design network-on-chip (noc)-based communication systems

Giovanni De Micheli, Luca Benini, Srinivasan Murali

To tackle the increasing communication complexity of multi-core systems, scalable Networks on Chips (NoCs) are needed to interconnect the processor, memory and hardware cores of the systems. For the use of NoCs to be feasible in today's industrial designs, ...
