Try switching your emission type to All Points. Then revisit your Birth setting to reduce the Impulse Count. Turn it down to 1. You probably don't want 10,000 copies of all your input points generated per-frame.

Not sure if this is considered fast or clever, but you can use a divergence field with a negative value to attract smoke.

Using your screen shots, I assembled the network. I'm not getting the same extreme smoothness shown in your example animation. Can you share what settings you used on the wrangles? Should both back steps be synchronized? Is the trail a compute velocity?

You can run python code to customize Houdini on startup.
Create a "scripts" folder in side your Houdini 20.xxx folder and drop this code into a text file.
On my system, the file path is: C:\Users\Admin\Documents\houdini20.0
Save the text file with the exact name of "123.py" inside the scripts folder. Launch Houdini, and the code will run, setting your time line to the frame range.

I think that is by design. You have to specifically let the node know want to control the length from an attribute.
Technical Discussion » Cooking issue in Houdini 20 when caching to disk

Funny you mention it. I recently experienced something similar while trying to scrub a cache. It kept cooking up stream. It didn't make sense because my display and template flags were on the FileCache, which fetched loaded data. I even move the cache node into a new, empty Geometry node. It wasn't until I closed Houdini, relaunched and created a new File node to reference the cached data that I could finally scrub it.
I was using H20.547.

Solaris and Karma » Solaris does not recognize Python-made Karma materials

I'm no Solaris expert, but I think Solaris is built on pathing, so where things are located is highly important.
I altered your code, and it worked to create a material subnet inside a material library on stage. However, the subnet was empty in both test context. Maybe Solaris isn't recognizing it because there is no actual material in the subnet.

Wouldn't you need to create the materials inside a material library instead of the /mat context? Perhaps alter your hou.parent path to point to a Solaris-based node?
hou_parent = hou.node("/stage/materiallibrary1")

No geometry nodes are needed. It's part of Blender's Data block processing. Blender can natively extrude any curve.

Sometimes, it's easier to assign your debug into to an attribute instead of printing it. Then you can examine the value per-point inside the geometry spreadsheet.
s@debug = sprintf("%f",999);

I generally perform Alembic exports from the /out context. Try adding an AlembicROP. Generally speaking, you may want to add s@name or s@path to the primitives you're exporting and then choose build hierarchy from that attribute.

The problem is using that RemeshGrid node. I'm not sure why you need to remesh, but don't use that one. Try the new Quad Remesh (Beata)node available with the H20 release.
Solaris and Karma » Karma PNG bit depth

The comper could use After Effects 3D tools to extract the depth pass, and write it out as a PNG sequence. Not sure what the point is, however. That would be downgrading your depth value from 16 bit to 8 bit, losing precision in the process.
