CIFellows Postdoc Job Opportunities

Posted on: Monday, October 19th, 2009

Job Details:

The Oak Ridge National Laboratory invites applications for Postdoctoral and Post-Master’s term research appointments in the Computer Science Research Group of the Computer Science and Mathematics Division. The appointment is initially limited to one year from start with an option for a second year contingent to funding availability. It is part of a research project that aims at developing a soft error resilience strategy for future-generation extreme-scale high-performance computing (HPC) systems. Soft errors are an emerging threat for these systems. Uncorrectable errors that occur in an ECC memory module once within a few million hours can cause a system error rate of a few hours. Also, undetected errors (silent data corruptions) are becoming a problem as well.

This project targets two different solutions: (1) checkpoint storage virtualization to significantly improve checkpoint/restart efficiency, and (2) software dual-modular redundancy (DMR) to eliminate rollback/recovery. The planned checkpoint storage virtualization aggregates a variety of back-end resources, such as flash, memory, or both, and uses them in conjunction with traditional parallel file systems. The core concept of the planned DMR technology relies on software-level replication of computational processes and on process cloning for fast recovery. The project will involve multiple facets of software research and development (design, implementation and evaluation) in storage systems, rollback recovery and process redundancy, including but not limited to:

• Storage: Distributed storage system, parallel I/O, user-space file system (FUSE), aggregated storage, caching, storage and I/O virtualization, LUSTRE parallel file system, SSD, performance analysis of storage systems
• Redundancy: Active replication, state-machine replication, process group communication, process cloning/migration, message logging, performance analysis of fault tolerance protocols
• OS/RTE: Linux, MPI

Qualifications:

The successful candidate is expected to have experience in C programming, system software development (Linux kernel development is a plus), high-performance computing, file systems development, network programming, and fault tolerance for parallel and distributed systems (active replication is a plus). This person will have excellent communication skills and the ability to work as part of a team. Applicants should clearly state relevant experience and skills, including level of proficiency, and indicate whether they are seeking a research-oriented or software development position.

For a postdoctoral position, an earned Ph.D. in computer science, computer engineering or a closely related discipline is required. A successfully defended Ph.D. dissertation is considered acceptable to start the appointment with the expectation that the Ph.D. will be granted at the close of the next academic term of the granting institution.

For a post-master’s position, an earned master’s in computer science, computer engineering or a closely related discipline is required. For this appointment, the master’s degree must have been completed and granted by the university at the time of starting the appointment.

Applicants cannot have received the most recent degree more than five years prior to the date of application and must complete all degree requirements before starting their appointment.
