Using focused regression for accurate time-constrained scaling of scientific applications
Many large-scale clusters now have hundreds of thousands of processors, and processor counts will be over one million within a few years. Computational scientists must scale their ...

Real-Time Biomechanical Simulation of Volumetric Brain Deformation for Image Guided Neurosurgery
We aimed to study the performance of a parallel implementation of an intraoperative nonrigid registration algorithm that accurately simulates the biomechanical properties of the b...

Selecting the tile shape to reduce the total communication volume
In this paper we revisit the tile-shape selection problem, that has been extensively discussed in bibliography. An efficient approach is proposed for the selection of a suitable t...

A Counterexample to Strong Parallel Repetition
The parallel repetition theorem states that for any two-prover game, with value 1 − (for, say, ≤ 1/2), the value of the game repeated in parallel n times is at most (1 − c)â...

Parallel mixing
Efforts to design faster synchronous mix networks have focused on reducing the computational cost of mixing per server. We propose a different approach: our re-encryption mixnet...
