 +Since 2018/09/27 there are new nodes ''​mn[15-20]''​ using the //skylake// chipset/​microcode. One can select just these cpus by using the -C flag.
 +<code bash>​sbatch -C skylake slurmexample.sh</​code>​

 +For best performance one should recompile the code for these machines, meaning one needs to tell the compiler that skylake optimization is required. How to do this varies depending on compilers. See [[https://​en.wikichip.org/​wiki/​intel/​microarchitectures/​skylake_(server)#​Compiler_support]]
