You might want to enable "numa interleave" for Maria (if your instance will use more than the memory of a single physical CPU for example), for that you can pass the option "--numa-interleave" to mysqld_safe or simply add "numa_interleave" in the configuration under the "[mysqld_safe]" section. Dont forget to install the "numactl" package before if you dont want to end up having MariaDB to fail to (re)start as its required to enable the "numa_interleave" option. Its usually better to use this approach to inverleave only what you decide to rather than forcing it system-wide on the bios. Le 05/08/2015 03:55, Daniel Black a écrit :

Hi guys i'm comfiguring linux kernel, there's some valid numa comfig at kernel to check? Why? Most distro kernels have most options enabled including NUMA support.
It's a xeon server with 2 cpu and 10cores each $ numactl --hardware
shows hardware. E.g the following from a non numa.
