I agree with Wolfgang... My first version of the rules regarding expiration of events in a length sliding windows took 120s in my benchmark. After thinking a little bit, the second version took 2s. Changed dramatically the behavior of the application, now can process several thousands of events in no time! If I were you, my first try was to optimize the rules, doing some benchmark/profiling, to know where the bottleneck is.

There is neither a "golden rule" nor a "silver bullet". Understanding what a rule does on the assembly of your facts is crucial. You may get by, happily, with an occasional deviation from some normal form, and you may be bitten, severely, by constantly neglecting it. -W On 19/05/2014, jonathan MERCIER <jmercier(a)genoscope.cns.fr&gt; wrote:

GPUs do not allow state/reference sharing. So it’s not as ideal as you think. Mark On 19 May 2014, at 18:16, Anton Hughes <kurrent93(a)gmail.com&gt; wrote:
