SLIT you don't really need to implement. yeah but i'd heartily recommend implementing SLIT too. mind you it's almost universal non-existence means i've had to resort to userland measurements to determine node distances and that won't change. i guess i just wanted to grumble somewhere. -dean -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

SRAT is essentially just a two dimensional table with node distances. Sorry, that was actually SLIT. SRAT is not two dimensional, but also relatively simple.
