Parallel genehunter: implementation of a linkage analysis package for distributed-memory architectures

TLDR
Preliminary benchmarks indicate reasonable scalability of the algorithm for performing multipoint linkage analysis of genetic marker data on large family pedigrees, with parallel efficiencies of 75% or more on up to a few dozen processors.
Abstract
We present a parallel algorithm for performing multipoint linkage analysis of genetic marker data on large family pedigrees. The algorithm effectively distributes both the computation and memory requirements of the analysis. We discuss an implementation of the algorithm in the Genehunter linkage analysis package (version 2.1), enabling Genehunter to be run on distributed memory platforms for the first time. Our preliminary benchmarks indicate reasonable scalability of the algorithm for even small fixed-size problems, with parallel efficiencies of 75% or more on up to a few dozen processors.

Exploiting Performance Counters to Predict and Improve Energy Performance of HPC Systems

TL;DR: Experimental results for energy prediction and energy optimisation indicate that with no a priori knowledge of workloads sharing the platform the authors can save up to 24\% of the overall HPC system's energy consumption under benchmarks and real-life workloads.

Building an Online Domain-Specific Computing Service over Non-dedicated Grid and Cloud Resources: The Superlink-Online Experience

TL;DR: Improved system performance is obtained through a virtual grid hierarchy with dynamic load balancing and multi-grid overlay via the Grid Bot system, parallel pruning of short tasks for overhead minimization, and cost-efficient use of cloud resources in reliability-critical execution periods.

Application-Agnostic Framework for Improving the Energy Efficiency of Multiple HPC Subsystems

TL;DR: This work proposes a framework that performs on-line analysis of an HPC system in order to identify application execution patterns without a priori information of their workload and takes advantage of reoccurring patterns to reconfigure multiple subsystems dynamically and reduce overall energy consumption.

Parametric and nonparametric linkage analysis: a unified multipoint approach.

TL;DR: It is shown that NPL is robust to uncertainty about mode of inheritance, is much more powerful than commonly used nonparametric methods, and loses little power relative to parametric linkage analysis, and appears to be the method of choice for pedigree studies of complex traits.

A General Model for the Genetic Analysis of Pedigree Data

TL;DR: Assuming random mating and random sampling of pedigrees, the likelihood of a set of pedigree data is developed in terms of the population distribution of the different genotypes.

Construction of multilocus genetic linkage maps in humans.

TL;DR: Several alternative algorithms for constructing human linkage maps given a specified gene order are described, one of which allows maximum-likelihood multilocus linkage maps for dozens of DNA markers in such three-generation pedigrees to be constructed in minutes.

The linear arrangement of six sex‐linked factors in Drosophila, as shown by their mode of association

TL;DR: Sturtevant et al. as discussed by the authors showed how genes are arranged along a chromosome and used the relative positions of six genetic factors on a fly's chromosome to identify regions of the chromosome that when mutated cause organisms to develop abnormally and to create treatments to cure those kinds of disorders.
