Empirical Evaluation for Graph Drawing (Dagstuhl Seminar 15052)

Authors: Ulrik Brandes, Irene Finocchi, Martin Nöllenburg, and Aaron Quigley

Published in: Dagstuhl Reports, Volume 5, Issue 1 (2015)

Abstract
This report documents the program and outcomes of Dagstuhl Seminar 15052 "Empirical Evaluation for Graph Drawing" which took place January 25-30, 2015. The goal of the seminar was to advance the state of the art in experimental evaluation within the wider field of graph drawing, both with respect to user studies and algorithmic experimentation.

Dynamic programming in faulty memory hierarchies (cache-obliviously)

Authors: Saverio Caminiti, Irene Finocchi, Emanuele G. Fusco, and Francesco Silvestri

Published in: LIPIcs, Volume 13, IARCS Annual Conference on Foundations of Software Technology and Theoretical Computer Science (FSTTCS 2011)

Abstract
Random access memories suffer from transient errors that lead the logical state of some bits to be read differently from how they were last written. Due to technological constraints, caches in the memory hierarchy of modern computer platforms appear to be particularly prone to bit flips. Since algorithms implicitly assume data to be stored in reliable memories, they might easily exhibit unpredictable behaviors even in the presence of a small number of faults. In this paper we investigate the design of dynamic programming algorithms in faulty memory hierarchies. Previous works on resilient algorithms considered a one-level faulty memory model and, with respect to dynamic programming, could address only problems with local dependencies. Our improvement upon these works is two-fold: (1) we significantly extend the class of problems that can be solved resiliently via dynamic programming in the presence of faults, settling challenging non-local problems such as all-pairs shortest paths and matrix multiplication; (2) we investigate the connection between resiliency and cache-efficiency, providing cache-oblivious implementations that incur an (almost) optimal number of cache misses. Our approach yields the first resilient algorithms that can tolerate faults at any level of the memory hierarchy, while maintaining cache-efficiency. All our algorithms are correct with high probability and match the running time and cache misses of their standard non-resilient counterparts while tolerating a large (polynomial) number of faults. Our results also extend to Fast Fourier Transform.

Local dependency dynamic programming in the presence of memory faults

Authors: Saverio Caminiti, Irene Finocchi, and Emanuele G. Fusco

Published in: LIPIcs, Volume 9, 28th International Symposium on Theoretical Aspects of Computer Science (STACS 2011)

Abstract
We investigate the design of dynamic programming algorithms in unreliable memories, i.e., in the presence of faults that may arbitrarily corrupt memory locations during the algorithm execution. As a main result, we devise a general resilient framework that can be applied to all local dependency dynamic programming problems, where updates to entries in the auxiliary table are determined by the contents of neighboring cells. Consider, as an example, the computation of the edit distance between two strings of length n and m. We prove that, for any arbitrarily small constant epsilon in (0,1] and n >=m, this problem can be solved correctly with high probability in O(nm + alpha delta^{1+epsilon}) worst-case time and O(nm + n delta) space, when up to delta memory faults can be inserted by an adversary with unbounded computational power and alpha <= delta is the actual number of faults occurring during the computation. We also show that an optimal edit sequence can be constructed in additional time O(n delta + alpha delta^{1+epsilon}). It follows that our resilient algorithms match the running time and space usage of the standard non-resilient implementations while tolerating almost linearly-many faults.
