Postdoctoral Position - Handling Anomalous Behavior in Large-Scale Parallel Programs - Radix and LANS

The Mathematics and Computer Science (MCS)  Division at Argonne National Laboratory invites outstanding candidates to apply for a postdoctoral position focusing on the development of innovative approaches to detecting and preventing abnormal behaviors in large-scale parallel applications.

The successful candidate will work with both the Radix Laboratory and the Laboratory for Advanced Numerical Simulation (LANS) teams on both basic and applied research topics, with the goal of accurate and efficient problem detection in petascale applications and beyond. For example, the successful candidate would perform research on collective behavior analysis by exploiting the fact that, in most SPMD applications, most of the processes are performing the same type of computation, but incorrect results or nondeterministic behavior can be caused by erroneous application code, as well as by events that are not under user control (e.g., scheduling decisions, network conflicts, nondeterminism in the network or communication library, memory access patterns).  This position involves interacting with users to understand problems, collaborating with other scientists at universities and laboratories, and presenting papers at workshops and conferences.

The MCS Division has a vigorous research program in applied mathematics and computer science, and provides access to world-class computing facilities, including a 2,048-processor Blue Gene/L supercomputer, a 100-teraflops Blue Gene/P system, and a 5.8-teraflops SiCortex system. Plans are also under way to scale up the Blue Gene/P during 2008 to be one of the largest computers in the world. In addition, the computational environment includes several other large Linux clusters, a distributed systems laboratory, and a virtual environments laboratory. For more information, see http://www.mcs.anl.gov.

Argonne is located in the southwestern suburbs of Chicago, offering the advantages of affordable housing, good schools, and easy access to the cultural attractions of the city.

Applicants must have recently received a Ph.D. in computer science or a related discipline and should have expertise in one or more of the following areas: graph algorithms, static program analysis, or behavior-based anomaly detection. Considerable knowledge is required in one or more of the following areas: parallel programming, scientific computing, parallel system software (schedulers, parallel file systems, etc.). Candidates should be able to create, maintain, and support high-quality software.

The appointment is for a one-year term (renewable). Via the Argonne website under division postdoctoral job openings for job requisition MCS-312681, candidates should submit a curriculum vitae; research proposal; list of publications, abstracts, and significant presentations; and the names of three references, other than Argonne staff, who can attest to the candidate's ability and potential.
