Effect of anisotropic characteristics on the mechanical behavior of asphalt concrete overlay

Lingyun YOU, Zhanping YOU, Kezhen YAN

Frontiers of Structural and Civil Engineering 2019, Volume 13, Issue 1, Pages 110-122 doi: 10.1007/s11709-018-0476-4

Abstract: The strength contributed by the AC overlay is strongly influenced by the anisotropic properties of theas well as to quantify the influence of the degree of anisotropy on the mechanical behaviors of AC overlayThe mechanical behaviors of the AC overlay were numerically obtained using the three-dimensional finiteVariations in the AC overlay’s modulus as a function of temperature as well as the contact state betweenthe AC overlay and AC layer were considered.

Self-deployed execution environment for high performance computing Research Articles

Mingtian SHAO, Kai LU, Wenzhe ZHANG

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 6, Pages 845-857 doi: 10.1631/FITEE.2100016

Abstract:

Traditional (HPC) systems provide a standard preset environment to support scientific computation. However, HPC development needs to provide support for more and more diverse applications, such as artificial intelligence and big data. The standard preset environment can no longer meet these diverse requirements. If users still run these emerging applications on HPC systems, they need to manually maintain the specific dependencies (libraries, environment variables, and so on) of their applications. This increases the development and deployment burden for users. Moreover, the multi-user mode brings about privacy problems among users. Containers like Docker and Singularity can encapsulate the job's , but in a highly customized HPC system, cross-environment application deployment of Docker and Singularity is limited. The introduction of container images also imposes a maintenance burden on system administrators. Facing the above-mentioned problems, in this paper we propose a self-deployed (SDEE) for HPC. SDEE combines the advantages of traditional virtualization and modern containers. SDEE provides an isolated and customizable environment (similar to a virtual machine) to the user. The user is the root user in this environment. The user develops and debugs the application and deploys its special dependencies in this environment. Then the user can load the job to compute nodes directly through the traditional HPC job management system. The job and its dependencies are analyzed, packaged, deployed, and executed automatically. This process enables transparent and rapid job deployment, which not only reduces the burden on users, but also protects user privacy. Experiments show that the overhead introduced by SDEE is negligible and lower than those of both Docker and Singularity.
