Job description:

Your Job:

The successful candidate will be part of the PRACE 6IP-WP8 Performance Portable Linear Algebra project and join the activities of SLQM within the Joint Lab Virtual Materials Design. The goal of this project is to provide a modern and efficient distributed linear algebra package based on HPX, that can replace ScaLAPACK in scientific applications, and help the developers of scientific applications in the process of adopting modern, performance portable, and distributed linear algebra libraries. In particular, the postdoctoral fellow will:

Contribute to the improvement of the Distributed Linear Algebra interface routines which compute the eigenvalue and eigenvectors Adding the ChASE eigenvalue solver to the library Integrate eigensolvers in Materials Science codes such as Quantum ESPRESSO and CP2K

Significantly contribute to the further development of the ChASE library such as

Distributed skinny QR decomposition Extend Cholesky-free support for generalized eigenproblems Include partial SVD computations

Your Profile:

A doctorate degree from a university with internationally accepted quality standards in computer science, software engineering, applied mathematics, or a related subject Comprehensive knowledge of numerical linear algebra theory and libraries is a must Experience in code development, C/C++ programming languages and in using scripting languages commonly used on Unix systems is a necessity Possessing good skills in parallel programming on distributed architectures is highly desirable A good attitude and willingness to work in an international, interdisciplinary and distributed team is desirable Scientific proficiency in algorithm design and its high-performance implementation is desirable but not strictly necessary Scientific interest in interdisciplinary research topics is a plus Very good knowledge of English in written and spoken form

Our Offer:

Opportunity to carry on high-impact scientific research in an open and dedicated team Visibility in the community-at-large and collaborations with the major international players in the field Possibility to develop your academic career and engage in the supervision of master and doctoral students Exciting working environment on an attractive research campus with excellent infrastructure, located between the cities of Cologne, Düsseldorf, and Aachen International and interdisciplinary working atmosphere A comprehensive further training programme Flexible working hours and various opportunities to reconcile work and private life Limited for 2 years with possible longer-term prospects Full-time position with the option of slightly reduced working hours Salary and social benefits in conformity with the provisions of the Collective Agreement for the Civil Service (TVöD)
