This is what I've been developing at Purdue: detecting where the last reference to a memory was lost, aiming to help fix memory leaks. It's written on top of the LLVM compiler infrastructure.
It's still in development as an out-of-tree project and needs some more work :)
However, I believe this could help in resolving memory leaks.

Good bye Purdue University!
It has been so intense, now suffering from jet lag and getting back to real life.

I got a reply from Lenovo HW team. For a reason that I don't understand, he said a part of 32GB DIMM belongs to a dual channel with 8GB DIMM and the remaining part belongs to a single channel thus a separate NUMA node.
```
[...]
the summary is that the performance for the two nodes is different. Node 0 is dual channel interleaved whereas Node 1 is single channel - so this is working as designed.
