Hi Lydia,
aggregators are automatically reset at the beginning of each iteration. As
far as I know, the reset() method is not supposed to be called from user
code. Also, in the code you pasted, you use "aggregator.getAggregate()".
Please, use the "getPreviousIterationAggregate()" method as I wrote
Hi Vasia,
okay I understand now :)
So it works fine if I want to collect the sum of values.
But what if I need to reset the DoubleSumAggregator back to 0 in order to then
set it to a new value to save the absolute maximum?
Please have a look at the code above.
Any idea why it is not working?
Hi Lydia,
an iteration aggregator combines all aggregates globally once per superstep
and makes them available in the *next* superstep.
Within each scatter-gather iteration, one MessagingFunction (scatter phase)
and one VertexUpdateFunction (gather phase) are executed. Thus, if you set
an aggregat
Hi Vasia,
yes, but only independently within each Function or not?
If I set the aggregator in VertexUpdateFunction then the newly set value is not
visible in the MessageFunction.
Or am I doing something wrong? I would like to have a shared aggregator to
normalize vertices.

Hi Lydia,
registered aggregators through the ScatterGatherConfiguration are
accessible both in the VertexUpdateFunction and in the MessageFunction.
Cheers,

Hi,
I have a question regarding the Aggregators of a Scatter-Gather Iteration.
Is it possible to have a global aggregator that is accessible in
VertexUpdateFunction() and MessagingFunction() at the same time?
Thanks in advance,
Lydia
