Reduced hardware transactions
Alexander Matveev, Nir Shavit · 2013
For many years, the accepted wisdom has been that the key to adoption of best-effort hardware transactions is to guarantee progress by combining them with an all software slow-path, to be taken if the hardware transactions fail repeatedly. However, all known generally applicable hybrid transactional memory solutions suffer from a major drawback: the coordination with the software slow-path introduces an unacceptably high instrumentation overhead into the hardware transactions.
