The strength of TM is to enable a +novel use of multithreading, inheritently safe, and not limited to +special use cases like other approaches. This talk will focus on how it +works under the hood.</p> +</div> +<div class="section" id="description"> +<h1>Description</h1> +<p>PyPy is a fast alternative Python implementation. Software +Transactional Memory (STM) is a current academic research topic. Put +the two together --brew for a couple of years-- and we get a version of +PyPy that runs on multiple cores, without the infamous Global +Interpreter Lock (GIL).</p> +<p>The current research is based on a recent new insight that promises to +give really good performance. The speed of STM is generally measured by +two factors: the ability to scale with the number of CPUs, and the +amount of overhead when compared with other approaches in a single CPU +(in this case, with the regular PyPy with the GIL). Scaling is not +really a problem here, but single-CPU performance is --or used to be. +This new approach gives a single-threaded overhead that should be very +low, maybe 20%, which would definitely be news for STM systems. Right +now (February 2014) we are still implementing it, so we cannot give +final numbers yet, but early results on a small interpreter for a custom +language are around 15%. This looks like a deal-changer for STM.</p> +<p>In the talk, I will describe our progress, hopefully along with real +numbers and demos. I will then dive under the hood of PyPy to give an +idea about how it works. I will conclude with a picture of how the +future of multi-threaded programming might looks like, for high-level +languages like Python. I will also mention CPython: how hard (or not) +it would be to change the CPython source code to use the same approach.</p> +</div> +</div> +</body> +</html> _______________________________________________ pypy-commit mailing list [email protected] https://mail.python.org/mailman/listinfo/pypy-commit
