Van Zee field@cs.utexas.edu Date: March 25, 2019 Subject: BLIS 0.5.2 now available We are pleased to announce BLIS 0.5.2, made possible in part thanks to contributions from the community as well as funding from NSF and industry. BLIS is a software framework for rapidly instantiating high- performance BLAS-like dense linear algebra operations. Aside from being a developer's tool, the framework also allows end-users to build libraries that implement a superset of the BLAS, which can be called via conventional BLAS-like or object APIs, or via standard BLAS interfaces. (An optional CBLAS API is also available.) BLIS 0.5.2 provides optimized kernel support across a variety of microarchitectures, including Intel's Haswell/Broadwell/Skylake, AMD's Ryzen/Epyc, and ARMv7/ARMv8. Intel's AVX-512 instruction set is also supported for Skylake-X and Knights Landing. Our most exciting recent development is a new Performance webpage that showcases single-threaded and multithreaded performance of BLIS and other implementations of BLAS for a representative set of datatypes and level-3 operations on a variety of many-core architectures, including Marvell ThunderX2, Intel Skylake-X, Intel Haswell, and AMD Epyc [1]. For other links to code, documentation, mailing lists, publications, and related information, please visit the BLIS github website [2].

Oishi Job Description/ Requirements: This proposal sets out a research plan to investigate a hierarchical set of model equations that describe complex viscoelastic materials. Such fluids can be found in many industrial applications, as for instance problems involving process of plastic, oils, chemicals, foods and minerals. An important application of viscoelastic materials in complex geometries is related to the extrusion problem (or die swell) referred to as a die in polymer processing. In particular, in this type of flow there is a classical difficulty due to the stress singularity in the changing of the boundary conditions. The simulation of viscoelastic fluids with singularities presents challenges related to the accuracy, stability and convergence. Moreover, the presence of boundary layers can modify the solution of the problem in certain regions of the domain. In this way, this project is to focus on the improvements on the construction of numerical strategies using the asymptotic knowledge of viscoelastic stress singularity. The problems analysed will be defined in confined geometries, such as contraction and cross-slot flows, and with free surfaces, like stick-slip and extrudate swell. The development of this project will involve a synergy of the CEPID supervisor in numerical simulations with the expertise of a collaborator from the University of Bath-UK in asymptotic methods. Candidates must hold a doctoral degree in Applied Mathematics, or in a related area, with experience in simulation of viscolastic flows and asymptotic methods for the solution of these problems. Interested candidates should e-mail a CV and two letters of recommendation from university professors as soon as possible to: Prof. Dr. Cassio M.
