A few years ago I got the chance to learn about Software Transactional Memory for the first time while visiting MSR Cambridge. The great Simon Peyton-Jones and Tim Harris explained to me the thinking behind STM and how it might evolve. It was a tremendously interesting conversation. If you haven't watched that interview, I highly recommend it as a precursor to this one. Today, STM is no longer only a research project. The Parallel Computing Platform team is incubating and extending the technology, finding that it may in fact work in the real world... Of course, there is no silver bullet to solving the Concurrency Problem, but STM may be an important part of a larger solution (you've leraned a great deal about what Microsoft is up to in the concurrency and parallelism space here on Channel 9 and it should be somewhat clear by now that many of the technologies we've presented to you may end up as pieces of a broader solution...) Here, STM Program Manager Dana Groff and STM Principal Developer Lead Yossi Levanoni discuss the current state of STM and outline the work their team is doing to craft this incubation/research technology into a practical real-world solution (STM is not available yet for experimentation. It's in incubation. It's not known if or when STM will become a viable product.). So, how has STM evolved over the past two years, anyway? Tune in. Enjoy.
