Houdini Pdg concurrent tasks - randomly starting just one task instead of multiple ones

Deadline
1

Hi there.
Strange issue with Houdini’s pdg and Deadline workers on different machines seemingly randomly choosing to not start all the concurrent tasks.
I am using a deadline scheduler in a houdini topnet with concurrent tasks parameter set to 4, 8 or 12, but i get random effects
a) It works fine, each worker starts the amount of tasks assigned.
b) One worker starts multiple tasks, the other starts only 1 task (there seems to be no rule for which worker starts multiple tasks or just one)

I’ve had this problem intermittently throughout the years so I’d love to find out what it is that i’m doign wrong.

I think the PDG submitter is made by SideFX, there were some recent changes to the way submissions were made

Which versions of Deadline / Houdini are you using?

Thank you! i just posted this on the Sidefx forum as well.
I’m aware of the recent changes but this is an issue that i had before with other versions of Houdini and Deadline, so I believe this is an user error.
I am using Houdini 20.5.487 and Deadline 10.4.0.10
