blur texture

Hi everybody,

Is there a way to blur a texture using arnold ? Using the mipmap is not a option because we cannot plug any float into it and it doesnt work using arnold gpu in sop or solaris Houdini.
I came across the osl shader done for redshift community(Redshift-OSL-Shaders/Blur.osl at main · Maxon-Computer/Redshift-OSL-Shaders · GitHub), I tried to use it in arnold using a osl reader but I cannot adjust the parameters. they also seem different.
thank you
