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.
