Conference on Fast Direct Solvers

2018快速直接求解器大会将于2018年11月9日至11日在普渡大学举行。会议的目的是将来自不同数学和应用领域的研究人员聚集在一起，就快速直接求解器的最新发展交换意见，讨论应对当前挑战的潜在战略，鼓励新的多学科合作，并向更广泛的社区传播相关想法。鼓励所有相关领域的研究人员、学生和实践者参加会议和/或发表演讲。会议将为初级和高级研究人员、学生和实践者提供一个多学科的平台来讨论和建立新的合作关系。这些活动将有助于吸引来自不同背景的学生和初级研究人员加入这一领域，并激发学生对数学的兴趣。在科学计算、数据分析和工程模拟中，求解大型线性系统通常是一个关键的计算组成部分。直接求解器不需要迭代，非常健壮，并且具有各种其他吸引人的功能。然而，由于稀疏性的损失，传统的直接求解器对于大型稀疏系统来说通常是昂贵的。在过去15年左右的时间里，科学计算界见证了所谓的快速直接解算器的快速发展，这种解算器利用结构，可以实现比经典直接解算器高得多的效率，有时是数量级。本次会议将汇集来自不同领域的研究人员、学生和实践者，他们积极参与快速直接求解器的设计、研究和应用。被邀请和贡献的讲座将有助于为直接求解者提供新的工具和确定新的研究方向。预计这次会议将是一次有效的活动，既能促进快速直接求解器的发展，又能使更广泛的数值计算受益。网站：http://www.math.purdue.edu/~xiaj/FastSolvers2018/This奖反映了美国国家科学基金会的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

The 2018 Conference on Fast Direct Solvers will be held at Purdue University in November 9-11, 2018. The purpose of the conference is to bring together researchers from different mathematical and application fields to exchange ideas on the latest developments of fast direct solvers, discuss potential strategies for tackling the current challenges, stimulate new multidisciplinary collaborations, and disseminate relevant ideas to broader communities. Researchers, students, and practitioners from all relevant fields are encouraged to attend the conference and/or to give talks. The conference will provide a multidisciplinary platform for junior and senior researchers, students, and practitioners to discuss and to establish new collaborations. The activities will help to attract students and junior researchers from diverse background to join the field and also stimulate student interest in mathematics. This grant will be used to partially support the travel and lodging of junior researchers and students.In scientific computing, data analysis, and engineering simulations, solving large linear systems is typically a key computational component. Direct solvers do not need iterations, are very robust, and have various other attractive features. However, classical direct solvers are typically expensive for large sparse systems because of the loss of sparsity. In the past 15 years or so, the scientific computing community has witnessed quick developments of the so-called fast direct solvers, which exploit structures and can achieve significantly better efficiency than classical direct solvers, sometimes by orders of magnitude. This conference will bring together researchers, students, and practitioners from diverse fields that actively involve the design, study, and application of fast direct solvers. The invited and contributed talks will help to supply new tools and identify new research directions for direct solvers. The conference is expected to be an effective event to both advance the development of fast direct solvers and benefit more general numerical computations.Website: http://www.math.purdue.edu/~xiaj/FastSolvers2018/This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
