QPI will abort TSX transactions?

On a system with at least two NUMA nodes - will an accessing cache-lines from another NUMA node (through QPI) abort a RTM/HLE transaction?

I can't find a hint in the Intel documentation.

AFAIK, TSX uses the cc-snoop protocols so I would assume that the snoop protocol messages are not passed through the QPI.

With which error is the transaction aborted? With capacity error or memory confilct ...?

 

best regards,

Oliver
