The next PyPy sprint will be in Leysin, Switzerland, for the tenth time. This is a fully public sprint: newcomers and topics other than those proposed below are welcome.
Goals and topics of the sprint
The details depend on who is here and ready to work. We might touch topics such as:
- cleaning up the optimization step in the JIT, change the register allocation done by the JIT's backend, or improvements to the warm-up time
- STM (Software Transaction Memory), notably: try to come up with benchmarks, and measure them carefully in order to test and improve the conflict reporting tools, and more generally to figure out how practical it is in large projects to avoid conflicts
- vmprof - a statistical profiler for CPython and PyPy work, including making it more user friendly.
- Py3k (Python 3.x support), NumPyPy (the numpy module)
- added: cffi 1.0, trying out pygame+cffi on Raspberry Pi devices
- And as usual, the main side goal is to have fun in winter sports :-) We can take a day off for ski.
For a change, and as an attempt to simplify things, I specified the dates as 20-28 Februrary 2015, where 20 and 28 are travel days. We will work full days between the 21 and the 27. You are of course allowed to show up for a part of that time only, too.
Location and Accomodation
Leysin, Switzerland, "same place as before". Let me refresh your memory: both the sprint venue and the lodging will be in a very spacious pair of chalets built specifically for bed & breakfast: Ermina. The place has a good ADSL Internet connection with wireless installed. You can of course arrange your own lodging anywhere (as long as you are in Leysin, you cannot be more than a 15 minutes walk away from the sprint venue), but I definitely recommend lodging there too -- you won't find a better view anywhere else (though you probably won't get much worse ones easily, either :-)
Please confirm that you are coming so that we can adjust the reservations as appropriate. In the past, the rates were around 60 CHF a night all included in 2-person rooms, with breakfast. Now, the rooms available are either single-person (or couple), or rooms for 3 persons. The latter choice is recommended and should be under 60 CHF per person.
You need a Swiss-to-(insert country here) power adapter. There will be some Swiss-to-EU adapters around, and at least one EU-format power strip.
