A Theory Of Pricing Private Data

We describe the foundations of a market in which those seeking access to data must pay for it and individuals are compensated for the loss of privacy they may suffer.

Automatically Accelerating Non-Numerical Programs By Architecture-Compiler Co-Design

Automatically Accelerating Non-Numerical Programs By Architecture-Compiler Co-Design

HELIX-RC is a compiler/microprocessor co-design that opens loops to parallelization by decoupling communication from thread execution in conventional multicore architectures.

Technical Perspective: A Simple, Elegant Approach to Non-Numeric Parallelization

"Automatically Accelerating Non-Numerical Programs by Architecture-Compiler Co-Design," by Simone Campanoni, et al., proposes a modest hardware extension to support a new parallel execution model for small, non-numeric loops.

Technical Perspective: Pricing Information (and Its Implications)

"A Theory of Pricing Private Data," by Chao Li, et al., introduces a fascinating and complicated issue that arises on the buy-side of the market when buyers are interested in multiple linear functions of the same dataset.
