Re: Gelly Scatter-Gather Iteration, In a single superstep, GatherFunction.updateVertex invoked more then once

Would you perchance have an example program to demonstrate the unexpected behavior? Does this issue always manifest or are you only seeing duplicate calls under specific circumstances? On Mon, Oct 22, 2018 at 8:33 AM 曹建华 wrote: > Hi: > According to the code comment, in Scatter-Gather Iteration,

Gelly Scatter-Gather Iteration, In a single superstep, GatherFunction.updateVertex invoked more then once

2018-10-22 Thread 曹建华
Hi: According to the code comment, in Scatter-Gather Iteration, Gather.updateVertex is invoked once per vertex per superstep. But in my programming, i find GatherFunction.updateVertex was invoked more then once, is it a problem of the code comment, or a bug of Gelly. My flink version is 1.5.3 Does

Hi all I have an iterative algorithm implemented using Gelly scatter/gather. Using 8 workers of a cluster, I encounter the error "akka.pattern.AskTimeoutException", which I think the reason is heap size. Surprisingly, using 4 workers of the same cluster, my program is executed!!

Gelly Scatter/Gather - Vertex update

2016-06-14 Thread Alieh Saeedi
Hi everybodyIn Gelly scatter/gather when no message is sent to a vertex in one iteration, it will not enter the scatter function in next iteration. Why? I need all vertices enter the scatter function in all iterations, but some of them receive a message and will be updated. thanks in advance

Hi Alieh, the VertexUpdateFunction and the MessagingFunction both have a method "getSuperstepNumber()" which will give you the current iteration number. -Vasia. On 13 June 2016 at 18:06, Alieh Saeedi wrote: > Hi > Is it possible to access iteration number in gelly scatter/ga
