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年快速直接解决者会议将于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程序领域的研究人员汇集到有关快速直接求解器的最新发展的想法，讨论应对当前挑战的潜在策略，以应对当前的挑战，刺激新的多学科协作，并将相关的相关社区散布到广阔的社区中。鼓励来自所有相关领域的研究人员，学生和从业人员参加会议和/或进行谈判。该会议将为初级和高级研究人员，学生和从业人员提供多学科平台，以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。该赠款将用于部分支持初级研究人员和学生的旅行和住宿。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件。直接求解器不需要迭代，非常健壮，并且具有其他各种吸引人的功能。但是，由于稀疏性损失，经典的直接求解器通常对于大稀疏系统而言是昂贵的。在过去的15年左右的时间里，科学计算社区见证了所谓的快速直接求解器的快速发展，这些求解器利用结构，并且可以比经典的直接求解器，有时是按数量级来实现的效率明显更好。这次会议将汇集来自不同领域的研究人员，学生和从业人员，这些领域积极涉及快速直接解决者的设计，研究和应用。受邀的和贡献的会谈将有助于提供新的工具，并为直接求解器确定新的研究方向。预计会议将是一个有效的事件，既可以推进快速直接求解器的发展并受益更一般的数值计算。
