Q: Do I need to bring sheets and towels?

A: No -- see arrival details at the bottom of this page.

Q: I would like to go to the gym or to the pool on the weekend. Is that possible?

A: To gain entrance to Campus Recreation facilities, you will need to show your workshop participation letter, to demonstrate that you are a guest of the University. Entrance fees are $7-8 per day. Towel rental is $1; you can also bring your own. There are three types of lockers: coin operated, electronic key, and self-brought-locks. Visit the Campus Recreation site for facility hours and locations.

Q: I'm arriving between 7:45-9:30pm on Sunday night. Is there any possibility to register a little later or catch up with the others?

A: Yes. Registration is very informal -- mostly it's so people can meet a few others before the next morning and get their nametag and wireless username and password. If you don't want to have those things in the evening, you can simply show up at the workshop location Monday morning. If you'd like to join the others, here's what I would advise:

  • Take a cab from Willard to your lodgings, and check in. See arrival details at the bottom of this page.
  • Call Eric de Sturler on his cell phone (email Amy at amyoung@uiuc.edu to get the cell number) to find out where the groups has gone from the Union. They will stay within a 5-minute walking distance from the Illini Union, and go either to a pub or to a coffeeshop, depending on how the group feels.
  • He will tell you where they are, and you can quickly walk over. I will give him the nametags and wireless information.

Overview and Goals

Little iconApplied and computational mathematics and computational mechanics have greatly influenced each other, and the interaction between these fields has been very productive. The interaction between the computational physics, chemistry, and materials science and the applied/computational mathematics community has been much smaller. The organizers believe that a closer interaction between these communities would lead to similar great benefits to both. Therefore, we want to make it easier for computational mathematicians to start working on electronic structure problems.

This workshop aims to bring together people that would like to put together software (e.g. documented scripts to generate test cases), introductory material (reports/documentation), test libraries, and so on, to help researchers with a computational or applied math background (start) making contributions to electronic structure calculations with modest effort. This can take many forms, and the list below should be considered a suggestion rather than a definite plan. Brainstorming and planning how to make the most impact will be part of the preparation and the meeting.

The desired result of the meeting is concrete plans for collaborations to establish software, documentation, test libraries, etc., and for obtaining funding for this effort. It is expected that participants are willing to commit time toward this effort (their own or that of students and postdocs).

Program

The workshop will be held directly prior to 2008 Workshop on Recent Developments in Electronic Structure Methods (ESW2008).

We focus on the following four areas:

  • Density Functional Theory
  • Quantum Monte Carlo
  • Quantum Chemistry
  • Markov Chains

In addition, everyone is encouraged to consider how to establish sustainable and effective computations at the petaflop level in each area.

We will have short (~2hr) meetings (presentation, discussion, planning) on each topic and a general planning session at the end.

Organizing Committee

Tentative projects

Before the meeting, session chairs are encouraged to start discussions about topics on the meeting wiki.

Please contact one of the organizers to extend this list.

  1. Put together collections of matrices (or something similar) to test eigenvalue solvers for the various problems arising in Electronic Structure (such as the Kohn-Sham equations). These should be accompanied by a clear description of the problem and what results are desired, for example, (1) the smallest 1000 eigenvalues and corresponding eigenvectors are required, or (2) the invariant subspace associated with the smallest 1000 eigenvalues is required (but not individual eigenvectors), and so on. Obviously, several variants of results might be useful for slightly different problems.
  2. Put together short reports to get people going on a specific problem, in particular in relation to research in computational/applied mathematics that people might already be involved in. Such a report would include pointers to the literature, especially, overviews and succinct statements of meaningful problems, pointers to available software, and information on how to obtain a useful test problem (appropriate difficulty, size, physical/chemical/..., relevance)
  3. Repository of software. This needs to be software that non-experts can use to put meaningful problems together without detailed knowledge of the underlying software/programs and without detailed knowledge of the chemistry and physics. Some knowledge will be required, but preferably that should be acquired by reading some accompanying introductory materials. The goal is scripts that can easily be modified (following some input description) and then run existing public domain codes.
  4. Procedures to integrate newly developed (to be tested) software into existing libraries.

Arrival Information and Maps

How do I travel between Champaign and O'Hare?

How do I get to and from campus from the Williard (Champaign-Urbana) airport?

The Willard airport is 10-15 minutes from campus, and there are buses and taxis that go back and forth. As of May 2008, two airlines fly into Willard: Northwest and American. There are always taxis at the airport when flights arrive, but to get from campus to the airport it's best to call ahead for a taxi to meet you someplace on campus. (There aren't taxis driving around campus as they do in larger cities.) Taxis cost ~$10-15 per person, one way.

The Champaign-Urbana Mass Transit District (MTD) offers the Air Bus #27, which goes from campus to the airport, about once every hour on weekdays. For maps and schedules, visit http://www.cumtd.com/. A sample AirBus schedule is: http://www.cumtd.com/routeschedules/ByRoute.aspx?routeID=27&routegroupID=8
Any stop labelled "Illini Union" is very close to the activities and housing (Sherman Hall). The "Materials Research Lab" stop is in front of the workshop location. One way fare on a MTD bus is $1.

Getting to campus

How do I get to and from campus from the Illinois Terminal (train/bus station)?

The MTD buses go to and from Illinois Terminal quite often, even later at night. For maps and schedules, visit http://www.cumtd.com. Here's an example schedule, for Sunday evenings (after 8pm) http://www.cumtd.com/routeschedules/ByRoute.aspx?routeID=31&routegroupID=12

Any stop labelled "Illini Union" is very close to the activities and housing (Sherman Hall). The "Materials Research Lab" stop is in front of the workshop location. A bus ride costs $1. You can purchase bus tokens and passes on the bus, from the driver.

Taxicabs serving Champaign:

  • C-U Taxi (217) 359-UOFI (8634) http://www.cutaxi.com/
  • Checker Cab (217) 367-0000
  • Chicago Carriage Cab (312) 326-CAB1 (2221)
  • In Illinois TOLL FREE (866) 440-TAXI (8294)
  • Corky’s Cab Co. (217) 352-3121
  • Old Timer's Taxi Co. (217) 202-2775
  • Yellow Checker Cab (217) 355-3553

Housing

What about internet access at the dorms?

There are ethernet jacks in the rooms. The blue cables needed for computer access should be in each room (often in a drawer or closet). If the cables are missing, you can contact the front desk. There is also wireless connectivity in the common areas (lounges, lobby, etc.) Please do not plug any routers or bridges into the housing network. The most typical problem for connecting is using the wrong cable or having it plugged in the wrong way. The small end of the blue supplied cables must be in the wall jack. You can also call 4-1111 during the day to try to get help.

Do I need to bring sheets and pillows, etc?

The dorms will have pillow, made bed, blanket, towel, washcloth, and soap. You can request more blankets at the front desk, and exchange towels there, too.

Are there laundry facilities available in the dorms? What are they like?

There are usually laundry facilities in the basement of the building where you are staying. Machines accept quarters, and it costs $1 a wash and $1 per dry. There is a change machine in the room, and the front desk staff can provide change for small bills. We have no laundry soap available in the hall, so participants will have to bring their own or purchase supplies in local stores (desk staff can give directions - and there is a Walgreens drugstore within walking distance.
