Hi,
Some remarks about job stealing SPI:
1)You have some nodes that can proceed the tasks of some compute job.
2)Tasks will be executed in public thread pool by default:
https://apacheignite.readme.io/docs/thread-pools#section-public-pool
3)If some node thread pool is busy then some task of compute job can be
executed on other node.
In next cases it will not work:
1)In case if you choose specific node for your compute task
2)In case if you do affinity call (the same as above but node will be
choose by affinity mapping)
According to your case:
It's not clear for me what exactly you try to do. Possible job stealing
didn't work because of your weak node began executions of some tasks in
public pool but just do it longer then faster one.
Could you please share your full reproducer for investigation?
BR,
Andrei

HI there,
I have asked this question, however I asked it under a different and
resolved topic, so I posted the quest under a more suitable title. I
hope thats ok
We have tried to configure two compute server nodes one of which is
running on a weaker machine. The node running on the more powerful
machine always finished its tasks far before
the weaker node and then sits idle.
The node is not even sending a steal request, so I must have
configured something wrong.
I have attached the code for both nodes if you could kindly point out
what I am missing , I would really appreciate it!
