2019 Petascale Computing Institute – ORNL

Oak Ridge National Laboratory
Building 8600, RM C-156
August 19-23, 2019
11:00 AM – 6:00 PM (ET)


The goal of the institute is to enable computational and data-enabled discovery in all fields of study by teaching the participants to scale their computational codes to leadership-class computing systems.

The institute will be broadcast to host sites using full-duplex audio/video connections. Participants will receive training accounts, on-site mentoring, and the ability to ask questions of the presenters orally and via on-line chats.

Sessions will also be webcast on YouTube live, although participants will not receive training accounts and will only be able to post questions on-line. Participants must register to attend one of the Host Sites or to watch the sessions on YouTube. Recordings of the presentations will be made publicly available after the institute is completed.

NOTE: ORNL is one of many Host Sites participating in this institute – for a full list of Host Sites, please see the main 2019 Petascale Computing Institute event page.


The institute is free and open to everyone. The content is targeted to individuals conducting research and scholarship in all disciplines, including graduate and undergraduate students, postdocs, faculty, researchers, scholars, educators, and practitioners in academia, industry and government agencies.

The institute will be beneficial to research teams who are preparing to scale their codes to petascale-class resources, people who are working on parallel codes, or have a need to scale up computational codes and/or data analysis programs. Individuals who are current or pending users of large-scale HPC systems will benefit the most from this institute. People who do not have access to research codes, such as those using commercial packages, are not likely to benefit from the institute.


The institute will provide training accounts to participants who register to attend at one of the Host Sites. The training accounts will be provided on multiple HPC systems which are described on the main 2019 Petascale Computing Institute event page.

Participants watching the YouTube live webcast will not be provided with training accounts, due to security policies and procedures for setting up training accounts.


Participants are expected to have the following background, knowledge and experience:

  • Familiarity with programming in Fortran, C, C++, Python or a comparable language
  • Familiarity with Linux
  • Familiarity with use of clusters and/or HPC systems


Participants may attend the institute at one of the Host Sites to receive full support during the institute. At these sites, participants will be able to verbally ask questions of the presenters through two-way video conferencing facilities. Participants will receive training accounts on the available HPC systems. Staff will be available at each site to assist during hands-on sessions. Seating at each site is limited, and registration will be handled on a first-come first-served basis.

Alternatively, participants may view the live presentations via YouTube live, but with a significantly reduced level of support. Participants will be able to submit written questions through social media tools provided by the institute. Due to account allocation policies, participants will NOT be able to receive training accounts on the institute computing systems. Everyone wishing to view the YouTube live session must register.


See the main 2019 Petascale Computing Institute event page for the tentative agenda for the institute.


Argonne National Laboratory (ANL), the Blue Waters project at NCSA, the National Energy Research Scientific Computing Center (NERSC), Oak Ridge Leadership Computing Facility (OLCF), SciNet at the University of Toronto, and the Texas Advanced Computing Center (TACC) are organizing this free week-long Institute.


All participants attending one of the Host Sites or watching the YouTube live session must register. To register to attend the ORNL event in-person, please submit the registration form below.

Registration for in-person participation closes on Friday, August 2, 2019!

NOTE: To watch via YouTube or attend in-person at a different Host Site, please visit the main 2019 Petascale Computing Institute event page.

NOTES about transportation:

  • Knoxville is served by the McGhee Tyson Airport, which is located about 20-25 minutes from West Knoxville and about 30-35 minutes from Oak Ridge (depending on traffic). You will likely want to rent (or share) a car to get around, and also because Uber/Lyft will not be able to enter the laboratory.

For out-of-town participants, you can make a reservation to stay at the ORNL Guest House, or there are a number of nice hotels in the area. You can choose to stay in either Oak Ridge or West Knoxville. Staying in Oak Ridge will be a bit closer to the lab, but there will be more to do (after hours) in West Knoxville. A few hotels from each area are listed below, but there are many to choose from:

Oak Ridge Hotels West Knoxville Hotels
DoubleTree StayBridge Suites
Hampton Inn Fairfield Inn & Suites
TownePlace Suites Holiday Inn Express & Suites
