Attention students and mentors: the Summer of Code midterms open up on July 9th. This means students fill out an evaluation, and mentors also fill out an evaluation. Don’t forget, because completed evals from mentor and student both are necessary for a project to continue being funded.
This is a report for last week’s work, so this is week 6 we are in now, and the reports are week 5’s status. So:
If you have an Intel processor with multiple cores and hyperthreading support, you can compile a new kernel and try out Mihia Carabas’s GSoC work already; he’s created a test using the OpenSSL test case to time scheduling performance vs. number of threads.
Mihai Carabas posted some benchmarks for his work with the DragonFly default scheduler and hyperthreaded CPUs. The end result, for those who don’t like number analysis, is that CPU-dependent speeds are reliably constant because tasks are being evenly scheduled across available CPUs.
(Well, CPU threads, since this is hyperthreading, but you get the idea.)
I think it’s week four, at least.
Mihai Carabas, Vishesh Yadav, and Ivan Sichmann Freitas all have their weekly status reports up for Summer of Code. Unfortunately, Loganaden Velvindron received a great job offer out of the blue, so he no longer has time for Summer of Code. (He plans to continue involvement in DragonFly, however.)
Here’s your most recent weekly round of DragonFly/Google Summer of Code updates:
- Ivan Sichmann Freitas: 32 bit api status
- Vishesh Yadav: inotify and fs indexing service status
- Mihai Carabas: Add SMT/HT awareness to DragonFlyBSD scheduler
- Loganaden Velvindron: Privilege separation
Week 2 Summer of Code status reports from Loganaden Velvindron, Mihai Carabas (plus followup), Vishesh Yadav, and Ivan Sichmann Freitas are available. Ivan Sichmann Freitas also has a RFC on changes to DragonFly’s 32-bit API.
Three more weekly status updates from DragonFly/GSoC students: Mihai Carabas, Vishesh Yadav, and Ivan Sichmann Freitas. That’s all for the past/first week.
Loganaden Velvindron posted a terse update on the state of his Summer of Code work for DragonFly. I’m still waiting on the other students.
Each of the 4 DragonFly participants for Summer of Code have posted an introductory email and details of their projects. Here’s direct links to their posts for your reading convenience:
- Vishesh Yadav – Implement inotify interface and Indexing Service for Filesystem
- Mihai Carabas – Add SMT/HT awareness to DragonFlyBSD scheduler
- Loganaden Velvindron – Privilege Separation in DragonflyBSD
- Ivan Sichmann Freitas – 32 bit API for 64 bit kernels
(Yes, same format as my last post, but now the links are to their posts, not the sparse Google info pages.)
Google has announced their projects accepted for Summer of Code: DragonFly has 4 projects of the 1,212 funded:
- Vishesh Yadav – Implement inotify interface and Indexing Service for Filesystem
- Mihai Carabas – Add SMT/HT awareness to DragonFlyBSD scheduler
- Loganaden Velvindron – Privilege Separation in DragonflyBSD
- Ivan Sichmann Freitas – 32 bit API for 64 bit kernels
(Hopefully those links are to visible pages) We had way more good proposals than available mentors/slot, unfortunately. So if you didn’t get in, think about next year, or maybe look at doing the work on your own; there’s some great ideas out there that I’d like to see happen.
DragonFly has been given 6 slots (i.e. spaces for students) by Google for this year’s Summer of Code. That’s great! We have a crop of great student proposals this year, so far, so the biggest worry at this point is how to get to them all.
Student applications for Google Summer of Code (and DragonFly) can now be submitted, until April 6th. Now’s your chance!
Here’s the page, with a convenient mentor application note at the bottom. That’s the next step, so if you were thinking of mentoring, now is the time.
The organization application for DragonFly is in for Google Summer of Code. If you are thinking of working as a mentor or as a student, please let me know soon! We will know if we’re accepted (for the 5th time!) on the 16th.
Nick Prokharau’s project for Google Summer of Code last year was “Port PUFFS from NetBSD/FreeBSD”. Sascha Wildner has now committed that to DragonFly. It’s experimental, so the normal caveats apply.
It’s on, again! Not that there was any doubt. I need to collect potential mentor names before DragonFly can be involved, so you can guess what I’ll say next…
That would be a recent ATI card, though I don’t know exactly which model name. Samuel Greear has imported David Shao’s DRM work, originally for Summer of Code, last year. Most newer Radeons should work (?).
I got mine the other day, and here’s someone else’s.
