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:

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).
