We are looking for a postdoctoral researcher with expertise in numerical analysis who can contribute as a member of a dynamic, multidisciplinary team of computer scientists and applied mathematicians developing innovative techniques that address the data motion problem on next-generation high-performance architectures by dynamically adapting the size of the data representation. Essential qualifications are a strong background in numerical analysis, including analysis of solvers for linear and nonlinear systems of algebraic equations and discretization techniques for systems of partial differential equations; demonstrated ability to develop and to perform theoretical analysis of new numerical algorithms and to perform independent research; experience in applying numerical methods within a scientific application; experience programming in FORTRAN and/or C/C++ in a Linux environment and developing algorithms for parallel computer architectures; and effective verbal and written communication skills necessary to interact with a multi-disciplinary research team, to author technical and scientific reports and papers, and to deliver scientific presentations. Experience with analysis of algorithms in the context finite-precision arithmetic is preferred. This position is in the Computation Directorate within the Center for Applied Scientific Computing (CASC) Division.
