12th JLESC workshop (online)


12th JLESC Workshop

Objectives 

The workshop gathers leading researchers in high-performance computing from the JLESC partners INRIA, the University of Illinois, Argonne National Laboratory, Barcelona Supercomputing Center, Jülich Supercomputing Centre, RIKEN R-CCS and The University of Tennessee to explore the most recent and critical issues in advancing the field of HPC from petascale to the extreme scale era.

The workshop will feature sessions on these eight central topics:

  • Applications and mini-apps
  • Parallel Programming models and runtime
  • Performance tools
  • Resilience
  • Big Data, I/O and in-situ visualization
  • Numerical methods and algorithms
  • Advanced architectures
  • Artificial Intelligence

In addition to these tracks, dedicated sessions targetting more specialized scientific domains are planned. The target domains change for each meeting depending on the needs and interests of the JLESC community. For this meeting the target domains are computational fluid dynamics, computational biology and climate/weather research.

A key objective of the workshop is to identify new research collaborations and establish a roadmap for their implementation.

Most of the workshop is open to all participants from the JLESC institutions Illinois, INRIA, ANL, BSC, JSC, Riken R-CCS and UTK; faculties, researchers, engineers and students who want to learn more about Post-Petascale / Pre-Exascale Computing. In addition to the schedule with restricted participation, the 12th JLESC meeting will feature during the last workshop's day, February 26th 2021, as an open day, where attendance is open to anybody interested by any of the workshop related topics.

The OpenDay features 3 invited talks from leaders in the field presented along with 3 success stories from JLESC teams. The OpenDay invited speakers are Prof. Satoshi Matsuoka (Riken), Dr. Lois Curfman McInnes (ANL) and Prof. Torsten Hoefler (ETH).

Location/venue

For the workshop, we will use Zoom, Slack and, in particular, the Gather platform. For the whole event we will make use of a venue/map created by Virtual Chair specifically for this workshop. Using the Gather platform, you will be able to navigate your avatar through the event, meet people and join the talks. The map will be open to JLESC participants from 7am ET - 1pm ET, Feb 24-26, 2021. You can access the venue though the Virtual Chair landing page:

https://www.virtualchair.net/events/jlesc


For the Open Day (8.00-11.30am ET), the link to the Zoom webinar can be found in the plenary room of the Gather map or here:

Some notes concerning the event:
  • All sessions will be held using Zoom rooms, embedded into the Gather map.
  • All round table discussions will be held "in person" on the map at dedicated meetings points and cannot be accessed from the outside. Use the "locate" feature to find a speaker or colleague on the map and to meet at the meeting points.
  • For the Open Day (Feb 26), all JLESC participants are free to use the Gather map, while all non-JLESC participants will have to use the direct link to the Zoom webinar.
  • Make sure you have access to the JLESC Slack workspace (access to Slack is restricted to participants from JLESC member institutions)
  • Using Slack, we will provide most up-to-date information and here you can contact us directly in case you have any questions or problems.
  • There is at least one staff member in each session room who can help you navigate or enter/exit the sessions. In addition, there is a help desk in the Lobby. You can also contact us at the #help channel on Slack or directly on the map. As a last resort, you can of course write us an email at any time.
  • Please monitor the Slack #announcements channel and your emails closely for updated information.
Some details concerning the platform:
  • Use the email address you provided during registration for logging in to the venue
  • Zoom links to the sessions are inside the different sessions’ rooms in the venue (press "x" to join Zoom when inside the session's room). If you really cannot use the map, contact us to get direct access.
  • When entering Zoom through the map, you will be automatically muted in the map. Make sure there is no feedback loop when being online in both systems. Mute, whenever possible, but don’t forget to unmute if you want to continue.
  • Use the minimap in the lower part of the screen to navigate. On the left, check out the calendar, the chat and the list of participants.
  • Please use a recent version of the Firefox or Chrome desktop browsers for accessing the map. Other browsers may work, but either unreliably or with limited capabilities.
  • In case things do not work as expected (e.g. video or audio fails), please simply reload the browser tab. You’ll be respawned in a few seconds directly where you left.
