[Apologies if you get duplicate copies] Postdoctoral Research Associate position available at OLCF ORNL
The Technology Integration (TechInt) Group at Oak Ridge Leadership Computing Facility (OLCF) at Oak Ridge National Laboratory (ORNL) is seeking applicants for the position of Postdoctoral Research Associate in HPC Storage Systems. The TechInt Group is responsible for updating and integrating the networks, files systems, and archival storage infrastructure into the OLCF computing systems. The group researches and evaluates emerging technologies and provides system programming to seamlessly integrate new technologies and tools into the infrastructure as they are adopted. As the OLCF computing resources continue to scale up, the TechInt group works to develop tools that allow users to take full advantage of the leadership-class systems. The successful candidate will work with a team at Oak Ridge National Laboratory to conduct research on existing and emerging high-performance scalable parallel file and object storage systems, such as Lustre and Ceph. The applicant will also be responsible for characterizing and analyzing high-performance computing (HPC) I/O workloads and developing I/O benchmarks, performance evaluation tools, and techniques mimicking these workloads. Required Qualification:_______________________ Candidate should have a Ph.D. in computer engineering or science, or related discipline. The following qualifications are also required: € C/C++ programming under Unix. € Shell and Perl or Python programming. € Technical comprehension of networking, and system software for HPC platforms. € Knowledge on high-performance networking technologies such as Infiniband or SAS and in-depth understanding of the TCP/IP stack. € Knowledge in performance analysis. € In-depth understanding in operating system kernels (Linux in particular), parallel tools, distributed computing and/or software development. € Collaborative skills, including the ability to work well with others. € Excellent verbal and written communication skills. Preferred Qualifications: _________________________ € Understanding of HPC computer architecture issues including CPU, memory, interconnect and parallel I/O. € Considerable expertise in parallel programming, multi-core systems, data flow analysis, and scientific application codes. € Considerable expertise in creating high-quality software. € Understanding in one or more of scalable parallel file systems, such as Lustre, Ceph, GPFS, PVFS. € Understanding in I/O middleware in HPC platforms. € Expertise in I/O performance evaluation and benchmarking techniques, tools, and methodology. € Expertise in storage area networking. € Knowledge of and familiarity with NoSQL databases, Key-Value stores, € Knowledge in Map-Reduce and scalable data analysis techniques.
