I'm not aware of any that does. In general applications usually only use the bare basics of NUMA API (if at all), the fancy stuff tends to be more slideware. If it's true then the correct place would be to fix the BIOS. > Maybe nobody does yet because > numa distances have never been available on x86_64 boxes... That's an incorrect statement. There are x86-64 boxes which report correct NUMA distances. -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
