Postdoctoral Research Associate - Large-scale Simulations

Oak Ridge National Laboratory

Job Description


Requisition Id 9824 

Overview

The Systems and Decision Sciences (SDS) group in the Computer Science and Mathematics Division (CSMD), Computing and Computational Sciences Directorate (CCSD) of Oak Ridge National Laboratory invites applications for a postdoctoral researcher with expertise in parallel computing, performance evaluation and tuning. The applicant is expected to be familiar with various types of simulations, such as continuous, time-stepped, agent-based, and discrete-event-based. The selected candidate will be involved in the development of large-scale simulation technologies to dynamically evaluate what-if simulation scenarios at extreme scales on leadership-class supercomputers. Additionally, the selected individual will have further opportunities to participate in multiple on-going inter-disciplinary research projects that uses advanced computing architectures.

 

Strong programming skills using C/C++ language and parallel computing libraries like, MPI are expected. Knowledge of programming hardware accelerators like GPUs, using CUDA and/or OpenCL is an additional plus. Good understanding of High-Level Architecture (HLA) standard would be helpful.

 

The SDS group is responsible for the design and development of computational solutions for the study of complex engineered and natural systems using scalable architecture-aware algorithms research coupled with innovations in mathematical and statistical methods. The group is part of the Mathematics in Computation (MiC) Section of the Computer Science and Mathematics (CSM) Division. MiC has a strong mentoring culture that provides junior scientists career and research guidance. CSM delivers fundamental and applied research capabilities in a wide range of areas, including applied mathematics and computer science, experimental computing systems, scalable algorithms and systems, artificial intelligence and machine learning, data management, workflow systems, analysis and visualization technologies, programming systems and environments, and system science and engineering. Projects frequently involve collaboration across scientific disciplines, and result in publications, prototypes, and technology transfer to both government and commercial uses.

 

Major Duties and Responsibilities:

  • Contribute research to one (or more) of ORNL’s principal areas of research in mathematics and computer science.
  • Collaborate with a highly diverse multidisciplinary team.
  • Report research results in open literature journals, technical reports, and at relevant conferences.

 

  Qualifications:

  • A Ph.D. in computer science, applied mathematics, or a related field completed within the last 5 years.
  • Experience in scaling parallel computing applications on very large machines, performance evaluation and analysis.
  • Experience with modeling and scaling parallel simulations.
  • Demonstrated effective written and oral communication skills 
  • Effective interpersonal skills

 

Preferred Qualifications:

  • Background in numerical linear algebra, probability theory, algorithms, or mathematical analysis.
  • Strong programming skill in C/C++ languages and working knowledge of MPI message passing routines. Knowledge of programming in Python or R would be an additional plus.
  • Candidate should be comfortable with Linux/Unix operating systems and in using version control systems like GIT.

 

Application Requirements:

  • A curriculum vitae.
  • A research statement that details the technical background and significance of the applicant’s research.
  • Three letters of reference describing the applicants’ distinct contributions to their field of research.  Please have letters sent to Ms. Kasi Arnold at arnoldkl@ornl.gov

 

Applicants cannot have received their Ph.D. more than five years prior to the date of application and must complete all degree requirements before starting their appointment. The appointment length will be for up to 24 months with the potential for extension. Initial appointments and extensions are subject to performance and the availability of funding.
