Houdini GPU afinity change after submittion

Hello,
At the moment it is not possible to change GPU affinity on Houdini job and redshift after it is already submitted.
As I saw all other programs can change GPU affinity in deadline monitor even after submitting job.
You can still change concurrent tasks for Houdini jobs but can’t change GPU affinity as well?

Hey mirkoj,

I’ve logged this internally, but in the mean time you can apply the fix yourself. It should be as simple as modifying “DeadlineRepository10/plugins/Houdini/Houdini.options” and adding the following to the bottom of the file:

[GPUsPerTask]
Type=integer
Minimum=0
Maximum=16
Label=GPUs Per Task
Category=GPU Options
Index=0
Description=The number of GPUs to use per task. If set to 0, the default number of GPUs will be used.
Required=false
DisableIfBlank=true

[SelectGPUDevices]
Type=string
Label=Select GPU Devices
Category=GPU Options
Index=1
Description=A comma separated list of the GPU devices to use specified by device Id. 'GPUs Per Task' will be ignored.
Required=false
DisableIfBlank=true

Now, any Houdini jobs that have those options set, you’ll be able to modify afterwards.

Cheers

works perfectly
thanks!!

It seems like this fix is not included in version 10.0.15.5, had add it manually again.
Just to check?

Yeah. Our Service Packs are built a while before they are shipped to customers (internal testing takes time). This code fix missed the SP15 boat, but I see it is already included in the SP16 boat. :wink:

Hello,
Seems like current fix isn’t working with latest deadline version?

10.0.15.5

Just applied same fix again and there is still missing GPU option.
It is also missing when submitting from deadline monitor, can;t select GPU per frame in there as well.
Any ideas?
Thank you!

EDIT:
Actauly here is issue that we missed first time.
Fix DOES work for jobs submitted with Houdini submit to deadline plugin
But submitting from Deadline Monitor Submit/3d/Houdini is missing GPU affinity options and also jobs submitted from deadline monitor are still missing GPU options as well.

So issue taht we missed last time is with submitting from inside Deadline Monitor :slight_smile:

Here’s a modified Houdini.options file that should give you the behaviour you want.

[attachment=0]Houdini_Options.zip[/attachment]
Gist of it is, the monitor does not set these values when you submit a job, so the plugin didn’t know about it. So we needed to specify the default values in the Houdini.options.

This change will not make it into the next release, but should be in the one after that.

Cheers

Great. Thanks for update! :slight_smile:
