What kernel version of Linux can install MapD?
MapD does not need a specific version of the kernel.
MapD is generally supported on Redhat/Centos version 7 -> and Ubuntu 16.04 ->
MapD does need a working Nvidia driver (nouvea will not work) to run on GPU. version 375.51 or greater
I do not have a GPU, can I still install MapD and use it normally?
sure you can , there is a cpu version too.
