Running Mantra In Nice Mode

[aracid]

hey all

does anyone here run mantra with

"nice -10 mantra" - in linux

to use low priority for rendering,

came across this and it really helps my machine handle background processing

does anyone know how to have linux run only this command automatically at this level of priority?

Use "alias"

Normally you launch Houdini from a terminal ok?

Well, put in you $HOME/.bashrc this:

alias mantra='nice -10 mantra'

You can do the same with commands like i3dgen for example.

Hope this helps.

You are welcome.

The magic of Linux, you can touch almost anything.

I'm not sure that will work as Houdini can't launch aliases. You could just replace the render command maybe?

You are right edward, aliases doesn't work.

So the only option i guess is to use a script to wrap the mantra command, something like:

#!/bin/bash

# mantra

exec nice -n 10 ./mantra.bin $@

Save the script with the name mantra, and save the original mantra command with the name mantra.bin, always in the Houdini's binary directory.

Anyway it would be great to have the option to choose the render priority, even more any render drive or ROP, priority execution.

Better use this code:

#!/bin/bash
# mantra wraper
exec nice -n 10 vmantra $@

Don't forget to give exec permissions to your new mantra wraper

Have you just tried changing the the Render Command parameter in the ROP to do this instead of using a wrapper script?

Yes edward you can do it too.

Maybe this option is more elegant that the wraper.
