Multiple Instances of aerender on the same worker
« on: December 12, 2017, 09:19:51 PM »
Is it possible for a worker to run multiple instances of aerender? Say my worker has 44 slots. If I give my job the reservation host.processors=4 and set it to have 11 instances, would that worker be able to pickup all 11 instances and run 11 instances of aerender?

Hi,

While technically possible it is not recommended to run more than one instance of aerender per worker.  The issue is that each instance of aerender will attempt to use all available cores on the worker, and in our experience this creates a higher rate of hung processes and failed frames.

Cheers,
