Jade is a data-oriented language for parallelizing programs written in a serial, imperative programming language such as C, FORTRAN, or C++. A Jade programmer simply augments the program with assertions specifying how the program accesses data. The Jade implementation dynamically interprets these assertions to execute the program concurrently while enforcing the program's data dependence constr...

As the complexity of computing systems grows, reliability and energy are two crucial challenges that will demand holistic solutions. In this paper, we investigate the interplay among concurrency, power dissipation, energy consumption and voltage-frequency scaling for a key numerical kernel for the solution of sparse linear systems. Concretely, we leverage a task-parallel implementation of the C...

This paper presents a parallel pipelined computer architecture and its six network configurations targeted for the implementation of a wide range of digital signal processing (DSP) algorithms described by both atomic and large grain data flow graphs. The proposed architecture is considered together with programmability, yielding a system solution that combines extensive concurrency with simple ...

The strength of the evidence linking concurrency to HIV epidemic severity in southern and eastern Africa led the Joint United Nations Programme on HIV/AIDS and the Southern African Development Community in 2006 to conclude that high rates of concurrent sexual partnerships, combined with low rates of male circumcision and infrequent condom use, are major drivers of the AIDS epidemic in southern ...

Optimism is a powerful technique for increasing concurrency. A program can gain concurrency by making an optimistic assumption about its future state, and verifying the assumption in parallel with computations based on the optimistic assumption. To date, use of optimism has been restricted to specialized systems due to the diiculty of writing optimistic programs. In this paper, we deene and jus...
