MPI-3-Forum meeting in Stuttgart - please reply ASAP
by Rolf Rabenseifner 08 Jul '10

08 Jul '10

Important hotel deadline: July 30, 2010. Therefore, please reply to me directly __now__ although your approval/paper work is not yet set up or finished. Dear MPI-Forum member, if you plan to come or not to come to the MPI Forum meeting in Stuttgart, Sep. 16-18, 2010, please send me a reply directly to rabenseifner(a)hlrs.de . Please do not wait, until your paperwork is done. My apologies that I could not ask you directly at the last meeting - therefore now as email. Your soon reply helps our administration and me. The hotel is the same as for the EuroMPI Conference and is optimally located, i.e., on our campus, location of EuroMPI, 15 minutes walk to HLRS (location of the Forum meeting), and with light rail connection directly from/to Stuttgart Airport (17 min), and also to the main railway station (11 min). Please tell/choose: Name: ___ YES/NO - I plan to attend the EuroMPI 2010 Conference (Sep. 12-15) YES/NO - I plan to attend the MPI-3 Forum meeting (Sep. 16-18) My planned stay at Stuttgart will be arrival date: ___ departure date: ___ number of nights: __ About the hotel, please choose one option: - I have already registered for the conference hotel within my EuroMPI conference registration process - I have not yet registered, but I plan to come and plan to stay in the proposed hotel. In this case, please tell me your preferred type of room: -- single: 74 Euro (Mon-Fri), 57 Euro (Sat, Sun) -- double: 91 Euro (Mon-Fri), 70 Euro (Sat, Sun) Prices per night and room, includes breakfast (same prices as for EuroMPI). If I have to cancel my plan, I'll inform you as soon as possible. - I plan to come but plan to use other accommodation. - I plan __not__ to come. - Other: ____ Please type in your business address: ______ Further details: ---------------- EuroMPI 2010 web page: http://www.eurompi2010.org/ The conference will be located in the hotel. MPI Forum meetings: http://meetings.mpi-forum.org/Meeting_details.php MPI Forum meeting location: HLRS ( http://www.hlrs.de/ ), Seminar room, Allmandring 30, 70569 Stuttgart, Germany. Map with all locations: http://maps.google.com/maps/ms?ie=UTF8&hl=de&msa=0&msid=1155291267861482270… (please take care that your browser takes the whole URL) Hotel web site: http://www.commundo-tagungshotels.de/en/stuttgart/overview-stuttgart.html Meeting Cost: $125 (not yet fixed) per person to cover meeting logistics costs. Travel information: Best is to fly in to Stuttgart Airport (STR, which is connected to most European hubs), e.g., flying directly from US to Frankfurt, Munich or Zurich with a connecting flight to Stuttgart (e.g., with Lufthansa, or Swiss). At the airport, you can use all "S-Bahn"s in the direction to Stuttgart (with final destinations Backnang or Schorndorf) leaving every 10/20 minutes 5:08am :18, :38, :48 until 10:08pm and then every 30 min until 0:08am. Another option is to use the only one direct USA-Stuttgart flight which is from Atlanta to Stuttgart (Delta). >From Stuttgart Airport to the hotel, the best and cheapest way is the "S-Bahn", our light rail system that directly connects the airport with "Stuttgart University" station (17 minutes ride). This station is 2 minutes from the hotel and about a 15 minutes walk from HLRS. A third option is to fly in to Frankfurt and to use the train to come to Stuttgart "Hauptbahnhof" (main station). The main station is also directly connected with "Stuttgart University" (11 min ride). (This third option may cause trouble because of ongoing construction work at the main railway station and therefore late or missed trains to Frankfurt!)

You should be able to build the LP solver you need from the functionality in PETSc and TAO.

Dear All: I need to use MPI parallel computing to solve large scale linear programmingmodel. I have searched online, but i cannot find any open source solvers. I would really appreciate if anybody can recommend a solver . thanks Jack July 7 2010 _________________________________________________________________ The New Busy is not the old busy.

I agree with Torsten - Atlanta is much more inconvenient than Chicago, even from the Westcoast. Based on my experience last time, it is more expensive to fly there and red eye/evening combinations (which work nicely between SFO and ORD) are much harder to accomplish (in particular when one tries to stay under $750 NSF funding). > >> March 28 - 30 - CA >> May 23 - 25 - Chicago >> July 18 - 20 - CA >> Sept - In conjunction with Euro MPI >> Nov 9 - 11 - In conjunction with SC (may want to move this to late >> Oct) > > I would propose more meetings in Chicago because it seems that more > folks are closer to Chicago (Argonne, IU, UIUC) than CA (Microsoft?, > Cisco?). You can add us to this list for west coast as well :) I would propose to go back to the original scheme of alternating between Chicago and CA. This seemed to have worked well in the past.

I suspect more of us will attend that than CUG. To accommodate both, I propose the week before IPDPS, i.e., MPI Forum May 9-11 Chicago. I agree with Rolf that fixing the dates sooner rather than later would be good. Having them on my calendar helps avoid conflicts (even if that is not always enough).
