2019 Undergraduate SIParCS Internship-Using Cloud-Friendly Data Format in Earth System Models
at University Corporation for Atmospheric Research
Job Title: 2019 SIParcS Undergraduate Student Internship
Project Title: Using Cloud-Friendly Data Format in Earth System Models
Location: Boulder, Colorado
Type: Internship, Full-time, Non-Exempt
May 20, 2019 through August 2, 2019
11 weeks, 40 hours per week
No relocation assistance is offered for this position.
Housing is provided for all students selected for the internship.
Application Deadline: January 11, 2019
- Students must be authorized to work in the U.S. to be eligible for the SIParCS program.
- UCAR/NCAR will not sponsor a work visa (e.g., J-1, H1-B, etc.) for this position.
- For F visa students accepted to the SIParCS program, CPT work authorization issued through a U.S. Designated School Official (DSO) or OPT issued through both a DSO and the U.S. Citizen and Immigration Services (USCIS) will be required.
About the Organization:
Located in Boulder, Colorado, the National Center for Atmospheric Research (NCAR) is one of the world’s premier scientific institutions, with an internationally recognized staff and research program dedicated to advancing knowledge, providing community-based resources, and building human capacity in the atmospheric and related sciences.
2019 SIParCS Program Description:
The Summer Internships in Parallel Computational Science (SIParCS) program at the National Center for Atmospheric Research (NCAR) offers graduate students and undergraduates who have completed their sophomore year significant hands-on R&D opportunities in high performance computing (HPC) and related fields that use HPC for scientific discovery and modeling. This program embeds students as summer interns in the Computational and Information Systems Laboratory (CISL), an organization within NCAR charged with provisioning supercomputing and data systems to the geosciences research community, as well as conducting research and development in computational science, data analysis, scientific visualization and numerical modeling. These twin roles of service and research in CISL support NCAR's broad scientific mission of discovery in the atmospheric and related sciences.
The 2019 summer internships are 11 weeks in duration. Applicants must be available to work 40 hours per week from May 20, 2019 through August 2, 2019 for participation in the program.
Program requirements, beyond working on projects, include attending appropriate technical seminars, attending skills-enhancing workshops, preparing a poster, and giving an oral presentation of results at the end of the summer.
Using Cloud-Friendly Data Format in Earth System Models
Areas of Interest:
- Application optimization/parallelization
- Software engineering
- Data volume of the earth system model is increasing rapidly every year, thanks to advances in computing efficiency and increases in model resolution and complexity. To efficiently produce these data volumes, parallel Input/Output (I/O) is a necessity, and to help manage data volumes, compression is also a necessity. Unfortunately, the commonly used data format Network Common Data Form (NetCDF) in earth system model does not support parallel I/O with simultaneous compression without significant performance loss. Alternatively, Zarr is a cloud-friendly data format that provides an implementation of parallel (multiple threads or processes) I/O for chunked, compressed, N-dimensional arrays. Experience with Zarr data format could provide us insights as to whether it can improve the parallel read/write/compression performance in the earth system model.
- Over this summer internship, the student will explore and learn about I/O development with Zarr library. The student will study how to use Zarr library and NetCDF library. The student will perform parallel benchmarks with both Zarr and NetCDF on NCAR’s Cheyenne supercomputer.
Please note: We will hire either an undergraduate or graduate student for this project.
Required for All Undergraduate Projects:
- Must currently be enrolled in an accredited United States college or university as an undergraduate student who has completed their freshman year.
- Ability to work with a diverse group of peers.
- Skill in the use of software for communication purposes (e.g. Word, Excel, PowerPoint, email).
- Ability and willingness to learn and use scientific computing tools and programs.
- Good oral and written communication skills.
- Basic problem solving skills.
- Ability to analyze data and draw conclusions.
- Basic knowledge, through coursework, of mathematics, computer science or engineering.
- Ability to work full-time (40 hours per week) during the summer program.
- Ability to interact with mentors and peers in a manner that supports collaboration and inquiry.
- Ability and willingness to work with a team.
- Ability and willingness to work within guidelines and policies of organization and assigned work groups.
Additional Required Experience for this Project:
- Familiarity with Linux or Unix.
- Experience with Python and C/C++ programming
Desired Experience for this Project:
- Familiarity with parallel computing
- Familiarity with scientific data formats
- Experience with NumPy
