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.

2018年快速直接求解器会议将于2018年11月9-11日在普渡大学举行。会议的目的是汇集来自不同数学和应用领域的研究人员，就快速直接求解器的最新发展交流思想，讨论应对当前挑战、刺激新的多学科合作并向更广泛的社区传播相关想法的潜在策略。鼓励所有相关领域的研究人员、学生和从业者参加会议和/或发表演讲。会议将为初级和高级研究人员、学生和从业者提供一个多学科平台，供他们讨论和建立新的合作。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该领域，并激发学生对数学的兴趣。这笔赠款将用于部分支持初级研究人员和学生的交通和住宿。 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关键的计算组成部分。直接求解器不需要迭代，非常稳健，并且具有各种其他吸引人的功能。然而，由于稀疏性的损失，经典的直接求解器对于大型稀疏系统通常是昂贵的。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求解器的快速发展，它们利用结构并且可以实现比经典直接求解器显着提高的效率，有时甚至高出几个数量级。本次会议将汇集来自不同领域的研究人员、学生和从业者，积极参与快速直接求解器的设计、研究和应用。受邀和贡献的演讲将有助于为直接求解器提供新工具并确定新的研究方向。此次会议预计将成为一次有效的活动，既能推动快速直接求解器的发展，又能使更通用的数值计算受益。网站：http://www.math.purdue.edu/~xiaj/FastSolvers2018/该奖项反映了 NSF 的法定使命通过使用基金会的智力优点和更广泛的影响审查标准进行评估，并被认为值得支持。
