Hello ,

We have some specific the requirement regarding the instance creation and can some let me know how can achieve this . 1) I have to pin each instance to a specif node .. that instance 1 should always run in compute node1 and instance 2 should run in compute 2 and so on.

2) I want to do a test with numa and without numa for each instance to verify the performance.That is ,lets assume my compute node has 512GB and 64 core CPU , I will create an instance of 500GB RAM and 60core CPU thats iw without NUMA . In next test I will create two instance that is 225GB RAM and 30core cpu with considering numa . Where I can configure the NUMA settings .That is these CPU core should use for this instance and so on .it should be in flavor or some where else ?

lscpu | grep NUMA
NUMA node(s):          2
NUMA node0 CPU(s):     0-15,32-47
NUMA node1 CPU(s):     16-31,48-63
