Milkyway@Home

• Distributed computing project

• Work on structure of Milkyway

• Tidal streams

• N-body simulation


Milkyway iOS

• Run 1 of 5 (sort of) fake workunits 1000x smaller than normal

• 10s desktop test takes 20 minutes, 8% battery

• E-mails me the results at [email protected]

• 143 people sent results, some many

Milkyway4iOS

• Get it from Peter’s Cydia repository

• “I haven’t looked at the Milkyway yet, cause that just came out”

• “Milkyway! What is it? What can I do with it?”

• “I don’t even know what this is for? Hope it helped you, and please update mobile notifier! So much potential for the best notification system!!”


What I’m doing

• Last presentation I forgot to mention my main goal for the semester

• (Still haven’t started that though, so it doesn’t matter)


CAL++

• Finally as fast (for the main part anyway)

• Apparently I was as fast for a long time and I’m just dumb

• (Well actually likelihood not done + other stuff, so a couple of extra seconds at the end)

• Need something besides a 5870 to test it


I broke the server

• All I wanted was a few minor scheduler fixes

• Now running SVN trunk server and everything is at least partially broken

• Slowly getting better


Lua

• Arbitrary initial distributions

• Less gross other configuration

• Better N-body tests


GPU N-body

• O (n log n) N-body much harder than the canonical GPU programming example

• Useless papers with no code (why are these publishable exactly?)

• Found a starting point
