A multicore GPU server for modeling hydraulic fractures

该方案旨在部署一个基于多个多核图形处理器单元（gpu）的并行架构工作站，用于水力裂缝的数值模拟。这台超级计算机由英伟达生产的消费级GPU构成，将包括1792个GPU内核，8个CPU内核，系统内存为72gb。该提案的目标是通过CUDA编程语言开发专门的算法，利用多核架构，实现水力裂缝扩展的快速建模。水力裂缝在石油、天然气和采矿业中具有重要的工业意义，并且作为不透水岩石中二氧化碳封存的关键组成部分正在被研究。预计该项目将为HQP提供一个理想的培训机会，使其掌握开发这种新型并行架构所需的专门技术。预计这些技术还将在科学计算的其他领域得到应用，这些领域与控制水力裂缝扩展的强耦合方程系统所面临的挑战相同。

This proposal aims to deploy a parallel architecture workstation based on multiple multicore Graphical Processor Units (GPUs) for the numerical modeling of hydraulic fractures. This supercomputer constructed from consumer GPUs manufactured by nVIDIA will comprise 1792 GPU cores, 8 CPU cores, and will have 72 GB of system memory. The objective of this proposal is to develop specialized algorithms that will exploit the multicore architecture via the CUDA programming language that will enable the rapid modeling of propagating hydraulic fractures. Hydraulic fractures are of great industrial importance in the Oil, Gas, and Mining Industries and are being investigated as a key component in the sequestration of CO2 in impermeable rock. It is expected that this project will provide an ideal training opportunity for HQP in the specialized techniques required to exploit this new form of parallel architecture. It is anticipated that these techniques will also find application in other areas of scientific computation, which share the same challenges as those encountered in the strongly coupled system of equations governing the propagation of hydraulic fractures.
