Re: [HTCondor-users] How to distribute jobs round robin

[John M Knoeller <johnkn@xxxxxxxxxxx>]

When using partitionable slots,  The Schedd can start more than one job on a single partitionable slot for each match that it gets from the negotiator.  This leads to something that appears to be depth-first matching. 

If you configure 

  CLAIM_PARTITIONABLE_LEFTOVERSE = false

In the Schedd, then it will start only one job for each match it gets from the negotiator, and then your negotiator matching policy will have more traction. 

The downside of this is that it will take many more negotiation cycles for a Schedd to fill up a partitionable slot.  And if your machines are going to end up completely full anyway, this is wasted effort.

Hi Michael,

Thanks for the quick reply!

Unfortunately it didn't work.. the jobs are still being scheduled to a single machine until full.
I also checked the docs now for NEGOTIATOR_DEPTH_FIRST and the default is false but I set it explicitly anyway.

Best regards,

Guilherme de Sousa Aranha

See NEGOTIATOR_DEPTH_FIRST, which was introduced in version 8.8.2.

If you set it to false, you should see the behavior you're looking for.
