1. A Programming Model for GPU Load Balancing

   https://doi.org/10.1145/3572848.3577434  

   Osama, Muhammad; Porumbescu, Serban D.; Owens, John D. (February 2023, Proceedings of the 28th ACM SIGPLAN Symposium on Principles and Practice of Parallel Programming)

   We propose a GPU fine-grained load-balancing abstraction that decouples load balancing from work processing and aims to support both static and dynamic schedules with a programmable interface to implement new load-balancing schedules. Prior to our work, the only way to unleash the GPU’s potential on irregular problems has been to workload- balance through application-specific, tightly coupled load- balancing techniques. With our open-source framework for load-balancing, we hope to improve programmers’ productivity when developing irregular-parallel algorithms on the GPU, and also improve the overall performance characteristics for such applications by allowing a quick path to experimentation with a variety of existing load-balancing techniques. Consequently, we also hope that by separating the concerns of load-balancing from work processing within our abstraction, managing and extending existing code to future architectures becomes easier.

2. Lateral load testing and 3D stress measurements in a pile foundation

   Farrag, Rabie; Slowik, Volker; Lemnitzer, Anne (September 2022, The 11th International Conference on Stress Wave Theory and Design and Testing Methods for Deep Foundations)

   Embedded sensors within infrastructure elements are powerful catalysts for new designs and construction methods, enabling advanced data collection and informed decision making. This paper presents the development, validation, and implementation of a prototype instrumentation tool utilized in large-scale lateral load tests of rock-socketed pile foundations, with the objective to measure shear stresses near the rock-soil boundary. The proposed instrumentation is novel in that it will be the first attempt to determine experimentally the 3D strain field through embedded sensors with immediate application to a broad array of pile foundation engineering problems. Data obtained from the prototype instrumentation is used to clarify whether shear force amplifications in piles crossing soils with strong stiffness contrasts are real, or an artifact of analytical, Winkler-based design methodologies. Three reinforced concrete pile specimens with a diameter of 0.46 m and a length of 4.9 m were subjected to reverse cyclic lateral loading up to complete structural failure. The sensors’ development, design, and construction, as well as their performance in measuring shear stresses will be discussed by comparing experimental data with predictions from conventional software tools. Ultimately, this study aims to improve the design and construction of more practical, resilient, and economical infrastructure.

3. Genomic signatures of inbreeding and mutation load in a threatened rattlesnake

   https://doi.org/10.1111/mec.16147  

   Ochoa, Alexander; Gibbs, H. Lisle (September 2021, Molecular Ecology)

   Abstract Theory predicts that threatened species living in small populations will experience high levels of inbreeding that will increase their genetic load, but recent work suggests that the impact of load may be minimized by purging resulting from long‐term population bottlenecks. Empirical studies that examine this idea using genome‐wide estimates of inbreeding and genetic load in threatened species are limited. Here we use individual genome resequencing data to compare levels of inbreeding, levels of genetic load (estimated as mutation load) and population history in threatened Eastern massasauga rattlesnakes (Sistrurus catenatus), which exist in small isolated populations, and closely related yet outbred Western massasauga rattlesnakes (Sistrurus tergeminus). In terms of inbreeding,S. catenatusgenomes had a greater number of runs of homozygosity of varying sizes, indicating sustained inbreeding through repeated bottlenecks when compared toS. tergeminus. At the species level, outbredS. tergeminushad higher genome‐wide levels of mutation load in the form of greater numbers of derived deleterious mutations compared toS. catenatus, presumably due to long‐term purging of deleterious mutations inS. catenatus. In contrast, mutations that escaped species‐level drift effects withinS. catenatuspopulations were in general more frequent and more often found in homozygous genotypes than inS. tergeminus, suggesting a reduced efficiency of purifying selection in smallerS. catenatuspopulations for most mutations. Our results support an emerging idea that the historical demography of a threatened species has a significant impact on the type of genetic load present, which impacts implementation of conservation actions such as genetic rescue.
