Database research in the real world. Big data vs. pundits – 1 : 0. Smdb’13 — the votes are in →. Testing the accuracy of query optimizers. January 6, 2013. A while back I had a very interesting conversation with Jack an application developer for a larger software company in the area; so to speak a person on the other side of the database. We talked about measuring the quality of an optimizer in this post. Earlier on and I’ve put forward a number of desiderata for an optimizer benchmark then. I recently f...

Database research in the real world. Testing the accuracy of query optimizers →. Big data vs. pundits – 1 : 0. November 7, 2012. So, after all it wasn’t such a ‘razor tight’ presidential race last night. Not that the Big Data camp expected one in the first place. Nate Silver. Just one day before the election. In short, independent of the political outcome of this election it’s a yet another great showcase where Big Data wins hands down over punditry! View all posts by Mike Waas →.

Maybe only 12 cannot find if they use hyper-threads. May use hyper-threads but limited by 16 FPGAs. A unit of parallelism (UoP) is defined as the maximum number of instructions that can execute in parallel on a single node for a single query. Since any program can start threads that wait I do not count these as UoP. On some CPUs. You are commenting...
