Cancelation policy If you cannot come to the course, please send an email to the organizer as soon as possible. This would allow us to accept additional participants from the waiting-list. There is no cancelation fee.
NO-SHOW: Registered persons that do not cancel and do not show up without any reasons are blocked for the next year on any of our workshops (because it is to expensive to produce unused copies of the slides for them).
Limit maximum of 42 participants in Stuttgart and Kassel, 35 in Dresden, Aachen and Manno, 34 in Garching, 26 in Jülich, 20 an der TUHH (according to the seats in the rooms).
Handouts Each participant will get a paper copy of all slides.
The MPI-1 part of the course is based on the MPI course developed by the EPCC Training and Education Centre, Edinburgh Parallel Computing Centre.
If you want, you may also buy copies of the standards MPI-2.2 (Hardcover, 17 Euro) and OpenMP 3.0 (about 8 Euro).
Most material of the course (including the audio information) can also be viewed in the ONLINE Parallel Programming Workshop.
