Bundle size problem
« on: December 08, 2017, 09:11:30 AM »

Hello,
I am using nothreads algorithm with multiplicator = 1 and servers have 16 core, so driver sending 16 tasks to nodes each time. If one of the tasks which sended to node in the same bundle takes more times to complete, the node couldn't take new tasks to fill its iddle threads because all of the task must be completed in the bundle to return to driver and take new tasks. I want all threads in the nodes be in use as much as possible even if same task requires more time to be completed. Is there a way to accomplish to this?

Are there any alternative ways to do this btw? I can't see it being done this way. Not 100% sure though.
