ROCK Hardware Transactional memory - Sun technical report

ROCK Hardware Transactional memory - Sun technical report
Abstract
We report on our experience with the hardware transactional memory (HTM) feature of two revisions of a prototype multicore processor. Our experience includes a number of promising results using HTM to improve performance in a variety of contexts, and also identifies some ways in which the feature could be improved to make it even better. We give detailed accounts of our experiences, sharing techniques we used to achieve the results we have, as well as describing challenges we faced in doing so. This technical report expands on our ASPLOS paper [9], providing more detail and reporting on additional work conducted since that paper was written.

"...In Sections 4 through 10, we present results from our experiments using HTM in a number of contexts: We use HTM to implement simple operations such as incrementing a counter (in Section 4) and a double compare-and-swap (DCAS). We then use the DCAS to reimplement some components of the JavaTM concurrency libraries (see Section 5). Next, we experiment with transactional hash tables (in Section 6) and red-black trees (in Section 7)..."
