Visitor and Internship Programs

The Computational and Information Systems Laboratory (CISL) at the National Center for Atmospheric Research (NCAR) regards collaboration with university faculty, practitioners in high-performance computing, new researchers, and students as central to its mission to support the atmospheric and related sciences. Below is a list of the visitor and internship programs hosted by CISL. Please read through program descriptions to decide which program is best for your visit. Click on program titles to access more information.

CISL Visitor Program (CVP)

Visits must be sponsored by a CISL staff member and have a clear plan for productive interaction. Please note that the CISL Visitor Program is not a "matchmaking" service. Applicants should have an established collaboration with a CISL staff member prior to applying for a visit.

The program does not support visits based on general interests. 

Visits are expected to last anywhere from 2 weeks to a maximum of three months. Requests for shorter or longer time periods, such as sabbaticals or student visits, will be considered on a case-by-case basis.

For scientific/technical level visitors, financial support is limited to a set living allowance for in-person visits.

For student visitors, financial support is determined on a case-by-case basis and may include salary support for either in-person or virtual visits. 

CISL Staff Sponsored Visits

This program is offered to CISL staff that would like to host a visitor outside of CVP.  Throughout the year, CISL staff are welcome to invite graduate/undregraduate students, PhD candidates, Post-Docs, scientific, and technical visitors. Supervisor and Division Director approval is needed before a visitor begins their appointment. Please contact the CISL Visitor Coordinator ( with questions.

SIParCS Internship Program

The Summer Internships in Parallel Computational Science (SIParCS) Program at the National Center for Atmospheric Research is aimed at university students who are interested in pursuing a career in areas such as:

  • Application Optimization
  • Computer Security and Formal Verification
  • Data Science
  • Numerical Methods
  • Software Engineering
  • Supercomputing Systems Operations
  • Visualization

The goal of the SIParCS program is to make a long-term, positive impact on the quality and diversity of the workforce needed to use and operate 21st century supercomputers. Graduate students and undergraduate students (who have completed their sophomore year by summer 2017) gain significant hands-on experience in high-performance computing and related fields that use HPC for scientific discovery and modeling.
