Re: [HTCondor-users] Total load average using multiple partitionable slots

["Beaumont, Martin" <Martin.Beaumont@xxxxxxxxxxxxxxx>]

Hello Jonathan,

 

One of my clusters is currently running on full load with partitionable slots.

 

OS: CentOS 7.6

HTCondor: 8.8.0 Jan 03 2019 BuildID: 457757 PackageID: 8.8.0-1

 

Partitioning config:

NUM_SLOTS = 1

NUM_SLOTS_TYPE_1 = 1

SLOT_TYPE_1 = auto

SLOT_TYPE_1_PARTITIONABLE = True

 

One (of 32 total) machine:

 

Compact result:

 

I personally don’t use condor to monitor load. I go with Ganglia.

Still works with a Linux CM and Windows exec machine, after some tweaking.

Subject: [HTCondor-users] Total load average using multiple partitionable slots

 

I’m struggling to interpret the load average metrics on machines that are configured with multiple partitionable slots.

As an example, here is the output of a basic condor_status command

condor_status [machine]

 

Slot 1:

 

Slot 2:

 

We can see that all of the dynamic slots have an average CPU load close to 1, which I would expect. However, running this in compact form produces:

 

 

The CpuLoad doesn’t seem to correctly capture the total load summed across all dynamic slots. I’m wondering if this is a bug, or if there is another way I can capture total CPU load on a machine like this.

 

Thanks,

Jon
