Project Update

[Dingo]

I just had a look at the Team standing and the L'Alliance Francophone are gaining on us rapidly.  they are now within 32 million of us and their average credit is more than ours.

When the AA is over please take some time and resources over to POGS so we can maintain our buffer and our # 1 position in the world.

If you are not participating in the AA please consider crunching POGS.

I swapped over for a couple days before the AA and I'll swap back to it after the AA, can't have em getting ahead that easily on our Aussie project!

Well said.+1 for your trouble

Will do.......just giving SIMAP some Team support during the AA, but may go back to POGS early.  (My preferred CPU project!)   

[daveandton]

They're still getting closer boys and girls. We can't let them overtake us can we?
Dave

[Dingo]

Yes #2 is getting close and they are contributing about 200K a day more than us.  I have deverted my old virtual PC's back over to POGS and will go 100% after the AA.

Hi All,

We're planning an upgrade for POGS in the next few months that will see us add more calculations to the suite already conducted on each galaxy image, add more data types (such as higher resolution images from the WISE telescope, http://www.nasa.gov/mission_pages/WISE/main/, which collects infrared light) and much, much more.

There are some big changes, and some smaller ones, included in the upgrade. We've given a short summary of everything below, but if you'd like any more specific detail or have questions then please let us know.

As part of the upgrades we intend to run some simulated galaxies through the upgraded POGS code as a check on the accuracy of our the data processing. These galaxy images are created by a computer to mimic certain characteristics. Once the fake galaxies are processed by the upgraded POGS 'spectral energy distribution' fit code, we can compare the results to the values we used when creating the galaxies to confirm the upgraded code works as expected and is producing accurate science results for the astronomers.

We're also upgrading the data retrieval pipeline, continuing to get enhanced infrared images from the WISE telescope for all galaxies that have already been processed, as well as some more galaxy data from other new sources. This new data will broaden our results on the galaxies that have been already processed - helping the astronomers to see more of the bigger picture, so to speak.

Kevin and the team will also upgrade the input data processing pipeline as well. This will include improving the smoothing of input images. They will also develop 'parameter prior cubes', sets of values that should be used in calculations on each galaxy image. This will stop us calculating every possible combination of parameters on every galaxy — saving time and resources. This also means we will be changing the credit system from the current points-per-pixel based model, as with 'priors' all pixels are no longer equal. We will let you know when the credit change will occur and will do our best to make sure it's equitable and results in approximately the same amount of credit you currently earn.

We will also be upgrading the output processing to produce better results images. This will include things like stellar masking (from catalogs, or directly from the images) to remove foreground stars from the calculations, and we also start using a code called 'galfit' (http://users.obs.carnegiescience.edu/peng/work/galfit/galfit.html) to give a mass surface density of the galaxies (a new calculation) and also try another code called 'CIGALE' (http://cigale.lam.fr/) and others on the data.

All of this comes together to mean better science output from POGS - something we're really keen on and we hope you are too!

Simap has only got five days of work units left until the end of the project and it's already down to four days now looks like it. So we could have early end to the AA. Good so we can give POGS a early boost. That project is going to get interesting from the update.

[Dingo]

Simap is still adding work and Batch Monitor still shows lots of work top do so it might last another week or so but if not I will be going 100% on POGS..  I am crunching POGS on some virtual machines that I rent out on the internet but they are not very good at BOINC as they are cut down on the CPU they can use.  I mainly use them as a web server and backup servers for stuff, always have too much stuff on my computers and always loosing it when they go

Speaking of Simap. Look at who is there user of the day.

I am an Aussie born in Canada over sixty years ago, lived in Australia most of my life, including 20+ years in the Australian Defence Force (Army). I was a Beta tester for BOINC and founder of team BOINC@AUSTRALIA currently crunching in all the BOINC projects.. Don't forget to look at my web cam

[daveandton]

L'Alliance Francophone  are really putting some effort into it now. I think they smell our blood. They are now crunching more than twice our number and gaining really fast.

Greetings All

Got 4 cores on POGS as we speak, will be trying to get another 4 cores up soon, and will running till XMAS, hey how about a 12 days of XMAS Challenge lol

Regards

[Hurricane]

Thanks for reminding me to switch over to POGS. Would have finished all Simap work over night. The PC would have been sitting there doing nothing, while I was having a sleep in.. Xmas POGS challenge doesn't sound so bad indeed.

[JugNut]

Yep a crissy POGS challenge sound good to me too, i'll be SIMAP dry by lunch tomorrow.

[LawryB]

Like the idea of a Xmas challenge just for B@A.   Have put 22 cores/threads onto the project..   

[kashi]

Yep me too, fired up Niresh Hackintosh on VirtualBox and it's Pogging away like a champion.

Go, go POGS.  biggrin
