MolSSI Workshop and ELSI Conference:

Solving or Circumventing Eigenvalue Problems in Electronic Structure Theory

August 15-17, 2018
Richmond, Virginia

The eigenvalue problem touches virtually every application of electronic structure theory to molecular or solid-state (materials) simulations. For small problems, traditional O(N3) eigenvalue solver libraries are often the most efficient solution to the eigenvalue problem, but for mid-to-very-large system sizes, several alternative solution strategies with lower scaling exponents eventually become the only viable options for practical simulations.

This workshop aims to bring together the broader community of researchers with an interest in scalable solvers for electronic structure theory for exchange of ideas and discussions – including, but not limited to:

  • Experts affiliated with different electronic structure codes from the quantum chemistry and computational materials science communities
  • Experts on solver libraries and strategies
  • Experts representing different, community-focused scientific software projects

In addition to the invited talks, the workshop will foster opportunities for in-depth interaction between all participants through a poster session early in the program (day 1) and through two dedicated “hands-on discussion” sessions. In the hands-on discussions, participants will self-organize into smaller groups to address topics of mutual interest. While some of the topics may be suggested by the organizers, others are expected to emerge organically from among the participants, ranging from small groups focused on trying out a specific software package, to discussion groups for strategic needs in a certain area, to implementation of a specific improvement in a software or code package emerging from discussion at the workshop.

The workshop will be held at The Graduate in the historic downtown area of Richmond, Virginia. Richmond is easy to reach by car, buses or trains, located about two hours south of Washington, DC.

Important Dates:

  • Registration deadline: July 6, 2018
  • Welcome and first talk: August 15, 2018 – 9 a.m.
  • Closing discussion and end of workshop: August 17, 2018 – 5 p.m.

Talks (Invited): We expect that invited talks will be 25 minutes long, followed by 5 minutes of discussion.

Posters (Contributed Abstracts): A poster session is planned for the first evening of the workshop.   Posters should have dimensions of 4 feet x 4 feet (122 cm x 122 cm) or less to fit on the provided poster boards.

Hands-On Discussions: Time will be reserved in the afternoons for Hands-On Discussions, providing dedicated time for the participants to split up into small groups to focus on topics of specific interest. Possible topics range from methodological improvements all the way to code development questions related to specific subgroups of participants and joint programming sessions.

Meals:  The poster session on Wednesday evening will include a light dinner and drinks. A conference dinner will be held on Thursday evening.

Location: See the “Locations” page for a map.

Program Schedule: A detailed program schedule and workshop booklet will be provided on this website closer to the event.
