This year’s EuroPVM/MPI was held in Helsinki (not quite, but close to it). I stayed in Hanasaari, a beautiful island with a small hotel and conference center on it. It’s a bit remote but nicely surrounded by nature.
The conference was nice, I learned about formal verification of MPI programs in the first day’s tutorial. This [...]

I just came back from lunch after the MPI Forum meeting in Helsinki. This meeting focused again (the last time) on MPI 2.2. We finished the review of the final document and edited several minor things. Bill did a great job in chairing and pushing the MPI 2.2 work and the overall editing. Unfortunately, we [...]

I attended the Hot Interconnects conference for the second time and it was as great as last year! This conference is rather convincing because it is a single-track conference with only a small number of highly interesting papers. And still, the attendance is huge, unlike on some other conferences where people only come when they [...]

We just finished all voting on the last MPI-2.2 tickets! This means that MPI-2.2 is fixed now, no changes are possible. The remaining work is simply to merge the accepted tickets into the final draft that will be voted on next time in Helsinki. I just finished editing my parts of the standard draft. Everything [...]

I’m just back from IPDPS 2009. Overall, it was a nice conference, some ups and downs included as usual. I had several papers at workshops from which I had to present three (I was planning on two only, but one of my co-authors fell sick and couldn’t attend). They were all very well received (better [...]

I did the Cluster Challenge again this year. Last year was fun, but this year was better – we won! Here’s the story:
We started Saturday morning in Bloomington. The travel went pretty
smooth and Guido picked us up at the airport in Austin. We went directly
to the Conference location. The time before that was very stressful
because [...]

Timo (my visiting student from Germany) and me are pretty much living in the UITS data-center (Wrubel building) these days. It’s a rather nice serverroom and we’re having our cluster directly next to the Data Capacitor and Big Red.
It was nice the last days, we stayed overnight during the weekend (more than 16 hours a [...]

Wow, LBL and Bereley is really cool. It’s basically at a large mountain. You can see San Francisco really well and the nature is great. I guess it’s really expensive . My talk went very good and the listeners were very interested (we had many discussions).
Here the view from the Lab to San Francisco:

I’m [...]

Update: visit also my Cluster Challenge page
Not much to add to the tagline. I was at SC07 . Oh, if you don’t know this conference … it’s one of the biggest in CS. There were about 9000 attendees this year. Actually I was supposed to go there to give my talk , [...]

Some pictures from the conference …

I am talking about non-blocking collectives here – we had an interesting question/discussion session afterwards .
  The reception in the French Senate – pretty classy .
Not too much more going on so far (besides some “pub-events” )
