 Posted: Mon Jan 30, 2012 12:01 pm Post subject: GPU Project of the Month Feb. '12 => Milky Way |
 |
|
By fending off challenges from GPU Grid and Moo! Wrapper, Milky Way won as the GPU Project of the Month for February 2012. Although KWSN has already shagged 'er for over 1.1 Billion points, we can finally scratch that "Virgin" off "The List". 
| Quote: | Milkyway@Home uses the BOINC platform to harness volunteered computing resources, creating a highly accurate three dimensional model of the Milky Way galaxy using data gathered by the Sloan Digital Sky Survey. This project enables research in both astroinformatics and computer science.
In computer science, the project is investigating different optimization methods which are resilient to the fault-prone, heterogeneous and asynchronous nature of Internet computing; such as evolutionary and genetic algorithms, as well as asynchronous newton methods. While in astroinformatics, Milkyway@Home is generating highly accurate three dimensional models of the Sagittarius stream, which provides knowledge about how the Milky Way galaxy was formed and how tidal tails are created when galaxies merge.
Milkyway@Home is a joint effort between Rensselaer Polytechnic Institute's departments of Computer Science and Physics, Applied Physics and Astronomy.

For those of *me* who do not own DP cards I am staying on Moo!
My GT220 has given me fits and I have retired using it, so I just have a couple of medium ATI cards that do the GPU crunching. |

Moo! seems to be hard on GPUs, one of my 5870's started taking much longer to complete tasks. Now I run at least one other project alongside it to let the GPU rest a bit every other half-hour.
As I recall, MW was down a lot then. So we had the PoTM annulled.

Yes MW was having significant issues this summer and fall. We now have a shiny new server and stability has been dramatically improved.

Yes, either that was annulled, virgin restoration surgery was performed, or that's the 2nd virgin memory failure I've had in 3 months. I must be getting old.  |

This forum is read by many from other teams, you might want to PM that sort of thing.

Remainder of the Double Credits: A Valentine's Day Present
A few weeks ago, we ran double credits in order to make up for a database error that occurred earlier in 2011. Unfortunately, the server crashed with just 12 hours left until the make-up credits were finished.
Now that the new server is up and running (and stable! very stable!), and everyone here is back from travels and winter break, we are ready to finish running those last 12 hours of double make-up credits.
If there are no significant objections, we'll run the double credits on St. Valentine's Day (February 14), from 10:00 am until 10:00 pm, US Eastern time (EST). This corresponds to 3pm (Feb14)-3am (Feb15) UTC.
Happy crunching! 5 Feb 2012 | 3:25:39 UTC · |

See announcement and discussion at link below:
| Quote: | Separation updated to 1.00
I've updated all of the separation applications to 1.00. For changes people might care about:
- The old CAL version is gone; it's replaced with the OpenCL application. On AMD/ATI GPUs (older than 79xx) it is using some hackery to use the same IL kernel as before so it should be as fast. However this also means the Radeon 38xx cards aren't supported with new stuff.
- Radeon 79xx stuff should work
- The occasional validate errors from empty / truncated stderr should stop
- AVX will be used if available on Linux and Windows (64 bit only for Windows)
- I've increased the default GPU target frequency so GPU stuff should make things less laggy on average. You can now also configure this with the web preferences now so you don't need to use app_info stuff if you want to play with that.
- Partial workaround with high CPU usage with recent Nvidia drivers.*
As usual post problems you run into here.
* It should cut down on the CPU usage a bit while not sacrificing too much. I would recommend not using it unless you are very unhappy with the CPU usage on Nvidia. There are options to change the polling mode if you want to lower the CPU usage further while not slowing it down. (--gpu-wait-factor (default = 0.75) and --gpu-polling-mode (default = - 2) work similarly to how they did with the old CAL one, but slightly different). With the default of -2 it will use mode -1 unless it is an Nvidia driver newer than the one that introduced the high CPU issue, where it will use mode 0. Mode -1 uses the correct waiting method, mode 0 use the correct waiting method with an initial sleep based on time estimates, and modes > 0 are a polling period in milliseconds. The wait factor is a sort of correction of the time estimate used for the initial wait. The default is 0.75, to wait for 75% of the estimated time before trying to poll.
