Approximate Range-Sum Queries over Data Cubes Using Cosine Transform
In this research, we propose to use the discrete cosine transform to approximate the cumulative distributions of data cube cells' values. The cosine transform is known to have...

Exploiting Single-Assignment Properties to Optimize Message-Passing Programs by Code Transformations
The message-passing paradigm is now widely accepted and used mainly for inter-process communication in distributed memory parallel systems. However, one of its disadvantages is the...

From Crash-Stop to Permanent Omission: Automatic Transformation and Weakest Failure Detectors
Abstract. This paper studies the impact of omission failures on asynchronous distributed systems with crash-stop failures. We provide two different transformations for algorithms,...

Short Vector Code Generation for the Discrete Fourier Transform
In this paper we use a mathematical approach to automatically generate high performance short vector code for the discrete Fourier transform (DFT). We represent the well-known Coo...
