What Your Job Will Be Like:

Sandia is seeking a HPC Performance Researcher and Analyst to advance performance evaluation for our current and prototype computing systems. This position is an outstanding opportunity to explore how applications perform in conjunction with systems and to influence next-generation HPC acquisitions.

In this role, you will work across three groups that collaborate to provide the research basis for new architectural designs through to the production realization of those systems in support of our scientific and machine learning applications. You will develop tools and analytics to provide continuous run time insight into the efficiency and performance of systems, applications, and facilities. You will develop and evaluate benchmarks and proxies for applications, and workflows to assess and predict performance on exploratory architectures. You will work with system administrators and users to discover and resolve issues in hardware, configuration and usage that affect performance.

Every day in our team is different, but typical activities will include:

• Work across research, development, and production teams to diagnose performance issues and to advise next-generation design decisions

• Develop tools and methodologies to evaluate large-scale application and system telemetry data at scale

• Develop, build, and run benchmarking, proxy, and application testing suites on current and prototype HPC hardware and assess architectural efficiency

• Participate in technical working groups evaluating, reviewing, and recommending architectures for the DOE national laboratories

This position is eligible for telecommuting and the selected applicant must live within a reasonable distance for commuting to the assigned work location when necessary.

Qualifications We Require:

• Master’s degree in Computer Science or relevant STEM field plus two (2) years of proven experience

• Two (2) or more years’ experience diagnosing and resolving performance issues in HPC applications (e.g., MPI-based) on large-scale systems (e.g., 100’s – 10,000’s nodes)

• Two (2) or more years’ experience running applications on HPC systems

• Ability to acquire and maintain a DOE Q Level clearance

Qualifications We Desire:

• Experience with HPC monitoring, tuning, and analysis tools (e.g., LDMS, VTune, Caliper, Darshan, Jupyter Notebooks) and/or benchmarking

• Experience building and tuning to address advanced architectural features such as GPUs, Burst Buffers, proprietary High Speed Networks, High performance filesystems, etc.

• Experience working with advanced developers to understand application internals to diagnose performance issues and to recommend improved use of HPC system resources

• Experience with performance portability layers (e.g., Kokkos) and architecture-specific programming libraries

• Experience developing scientific applications in C/C++ and experience with MPI

About Our Team:

The High Performance Computing (HPC) Development Department develops innovative solutions for the operation and efficient utilization of leading and next-generation computing systems across the world. Our Heterogeneous Advanced Architecture test-bed Platforms (HAAPs) are used to evaluate advanced processors and accelerators for next generation platforms. Our Advanced Technology Systems (ATS) testbeds support R&D necessary for extreme-scale application runs. These in-house systems enable our HPC Operational Analytics team to develop monitoring and analysis capabilities for advanced and diverse computing architectures.

Security Clearance:

Sandia is required by DOE to conduct a pre-employment drug test and background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications. Applicants for employment need to be able to obtain and maintain a DOE Q-level security clearance, which requires U.S. citizenship. If you hold more than one citizenship (i.e., of the U.S. and another country), your ability to obtain a security clearance may be impacted.

Applicants offered employment with Sandia are subject to a federal background investigation to meet the requirements for access to classified information or matter if the duties of the position require a DOE security clearance. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause a clearance to be denied or terminated by DOE, resulting in the inability to perform the duties assigned and subsequent termination of employment.
