Hot Interconnects (HOTI’09) in New York

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 have to present a paper and the audience is often sparse.

I gave a talk on static oblivious InfiniBand routing which was well received (I received a lot of questions and had very interesting discussions, especially during the breaks). Other highlights of the conference (in my opinion) were:

  • Fulcrum’s impressive 10 GiB FocalPoint switch design (the switch has full bandwidth at 10 GiB/s line-rate, real 10 GiB/s not 8 ;))
  • A paper about the implementation of collective communication on BG/P (I was hoping for a bit more theoretical background and a precise model of the BG/P network)
  • Some talks on optical networking were rather interesting
  • The panel about remote memory access over converged Ethernet was rather funny. Some people are seriously trying to implement the <irony> simple and intuitive </irony> OFED interface to Ethernet. I am wondering which real application (not MPI) uses OFED as communication API?

Here are some commented pictures:
View from the Empire State Building (credits go to Patrick!).

Another view from Empire State, the red arrow points at the conference location (the Credit Suisse Palace).

Times square (I think).

The Empire State “tip”.

Another downtown view.

The Empire State foyer.

I feel like in Paris ;).

We saw this scary building without windows as we walked from The Empire State down to the World Trade Center Site (weird).
*yeah* (seen next to the WTC site).

All we could see from the WTC site. It was not worth the long walk … but we talked anyway most of the time so this paid off.

The Wall Street (should be closed immediately!).

The subway is rather scary … seriously, New York!? Why do they have such a bad subway …

View from my (extremely cheap) hotel room. It was awesome, really!

The Credit Suisse Palace from the inside. Somebody has too much money (still).
