I got this from Ben Willet today. It's an animation which gives an example of what some of the n-body simulation workunits you guys are running are simulating.



And his caption from his thesis:

This animation shows N-body simulations of the Sagittarius (large),
Orphan (medium) and GD-1 (small) stellar streams. The Milky Way Galaxy is
shown edge-on, with the Sun located on the left side of the disk. The
legend shows the +Z direction, out of the Galactic disk. The stellar
streams are created by allowing spherical collections of particles to
evolve for four billion years within the Milky Way's gravity. The
Sagittarius and Orphan streams are formed from dwarf galaxies, whereas
the GD-1 stream is formed from a globular cluster. The Orphan Stream has
been used by Rensselaer researchers to imply a total Galactic mass less
than originally believed.

WOW, that looks amazing!

very cool. its nice to have a visual on the simulations we run.

My question would be is that sim generated from previous data, or the junk we're sending back lately??!! ;-)

Personally, I trust the stuff my hosts have sent back for N-Body since the upgrade about as far as I can throw my car! :-)

The only thing that really changed in the upgrade was the server code for determining credit, and whatever changes were made to the BOINC scheduler. Nothing different is being run on anyones machines (at least... when it does run).
