18th DIRAC Working Group Meeting 2015, Odense, May 7th - May 11th (Arrival May 6th)

For new people

The DIRAC meeting is a family reunion for DIRAC developers and DIRAC friends. It is a nice opportunity to meet the people behind the DIRAC code. There is no registration fee but for organization purposes please let Hans Jørgen know that you want to come.

Most people will stay at the campground (more info below). The cabins are very good comfort, not expensive, and it's fun to be there. Book them well in advance.

We will discuss science but a significant part of the program is reserved to discuss the future of the DIRAC code, programming, code maintenance, release planning, as well as for programming task groups.

The meeting program is self-organised, simply add talks and discussion points to the program.

How to get to Odense

Typically you will fly to Copenhagen or Billund and then take the train. From Odense train station you can take the bus or share cab to the DCU-Camping Odense.

Lodging

Make your cabin reservation at DCU-Camping Odense. The cabins can accommodate 3-4 people so organize with others. Use the dirac-developers mailing list.

Bus tickets

  • regular bus tickets cost DKK 23 for a single ride (including changing lines) and are valid for 1 hour.
  • alternatively you can “rent” a bus card at the 7-eleven store at the train station (deposit DKK 50 + DKK 10 per prepaid bus ride with this card. E.g. you ask for a card with 6 rides, cost DKK 110). Using this card the cost for a bus ride reduces to DKK 10.
  • arriving by train you can use your train ticket for the bus and get a free ride (to the campground).
  • bus routes (look along line 21 on page 3): http://www.fynbus.dk/wm141591
