IPC is over. My impression: The place was too big making it a little bit difficult to get in contact with others. Yet, from a technical and gastronomical point of view the Rheingoldhalle was a good choice. For the next IPC I would recommend to anker a hotel-ship near the hall (the Rheingoldhalle is situated at the bank of the river Rhine) to avoid a 30min shuttle bus ride from and to the hotel. ;-)
But back to my talk there.
The initial idea to this session was a performance consulting in spring this year: For a table with appr. 250 billion entries I found a way to store and read about 6,000 queries per second! I applied some very unusual ways to speed up a problem by factor 1,000 or 2,000 just by thinking about how I would do it, if I had to store the things in my home supposed they were real things such as cutlery.
I found out, that there are some patterns, which can be used in general and that they work for nearly every problem with very big tables. Just see for yourself how I solved the problem.
Please note: The slides could probably not be understood without explaining some of the ideas. Be free to post your questions as comment!
