I updated to 10.4 and H21 myself couple weeks back and it was pretty much the same as with 19 and 20. You need Deadline json to point to right place as as package and also submitter dir to both HOUDINI_PATH and HOUDINI_MENU_PATH. Then of course in that location you need to have deadline scripts and also python libs. It should look something like this: , json attached too.

I don't know why, but my guess is that OpenGL/Vulkan/UI is doing stuff on one of the GPUs.

I can confirm that Vulcan viewport(default in 20.5) is the cause of the performance loss when rendering in Solaris. Switching Houdini back to OpenGL cards are running at 49:50 utilisation(warehouse scene).

Thank you, I tried those env. vars and others(listed in docs) and found out what the issue is. It seems like it's connected to viewport/live render, meaning rendering directly in Houdini, Solaris desktop for example. It seems performance realy tanks when rendering like that. As a test scene i took the Warehouse from content library, should be easy to replicate.

Rendering with same settings and samples, to viewport 7:33 and to mplay 4:14 . Utilisation to mplay is perfect 50:50, but rendering in viewport the performance is 31:68 , or 160 v 352 passes. That`s close to half speed only for one for the cards. Images for both renders attached. Hope that helps to find out what the issue is.


Thanks!
