From Dave:

Haha yes, its actually completely ready and I think Travis has the apps up. We're just working on getting the web server to redirect the page correctly.

Although no word on ATI apps from Cluster or Gipsel.

MW is down right now, maybe project separation is at hand...

I don't have a graphics card on this PC, so maybe Team Troll will go to the GPU project and leave the other behind...

...nah. Can't see it somehow.

milkywy_gpu default project pages are up. It is also possible to register but so far no guarantee that you will keep the user ID you get as the project could be reset at any time :)

Once the GPU project is officially running,will our team automatically be registered? So far we don't appear in a team search, and I don't know whether I should be waiting for it to happen automatically or if I should wait for KM or someone else to register it?

Also, will we be treating it as a separate project (ie with a separate thread), or will they be the same project, from the teams point of view?

I don't know the answers to those questions, and KM is currently experiencing internet connection issues and Buga has mostly been absent over the last couple of weeks, so...

If the team doesn't exist when you register for real, create it, post here that you did, and be prepared to turn it over to KM once he gets registered. This has happened on other projects.

And as far as I'm concerned, we can keep this thread for both the CPU and the GPU projects, no need to split.

I'd agree with Labbie...I think that's spot on for what KM would say in the matter.

I saw last night that KM and Buga had both created accounts and that the team has been made.

Kind of a waste of time IMO, since I think Dave and Travis are going to wipe that DB one last time Sunday night before they go live.

But yeah, I created an account anyway.

What, you mean I have to stay awake all night Sunday night just to get a low numbered user ID (I'm sure that's the latest challenge :) )?

If it's that important to you.

Personally, I wouldn't mind letting all the Big Boys get in on the first day, and then come in later so I have a better chance being #1 on my start date.

Besides, we're not even sure that Travis' CUDA app will work or that Gipsel and Cluster will get/have gotten/willin be havin gotten

pre-release code to convert. It could be a week before we see an ATI app.

Actually no, it's not that important. Hence the smilie (or do I have to click an icon and have a pictogram in order to show when I am joking about something?).

I was actually taking the mickey out of those who have got competitive about it. The only reason I am user ID #12 on the GPU project is because when I happened to check the project and saw the basic pages were there, it just happened to not be long after the project had been reset. There was no planning, and will be no planning when the project starts (and if it is reset).

Hi Guys, sorry I've not been around for a couple of weeks. I've hardly got any MW work on about 9 machines. I'm assuming the GPU guys are pinching it all?

Post by **Labbie** » Fri Apr 24, 2009 7:09 pm

Probably more about the script guys than the GPU guys.

Sshhhh.

Post by **Chris S** » Sat Apr 25, 2009 1:13 pm

Yes I know about the scripts being used, and it hammers the servers so I'm not going to use them. As soon as they get the Cuda GPU app running I'll stop MW CPU work altogether. In fact on some of my slower machines I can get a higher RAC over at Nqueens.....

Front Page News!!!

Assimilator/Validator Back Up
May 18, 2009
Looks like the assimilator and validator is back up and working. Let us know if you have any problems.

Assimilator/Validator not working
May 18, 2009
I'm working on the assimilator and validator right now so hopefully I'll have them running shortly. Except a large news update this week by wednesday -- our CUDA application is almost working so it should be out by then. I'm just doing some last tests before I put out the alpha code for everyone.

Looks like the assimilator and validator is back up and working. Let us know if you have any problems.

The reason we went down today a few times was that there were power outages on campus while they were doing things to the electrical system. Hopefully things should be up and running smoothly now.

Another Power Outage
May 19, 2009
There's another power outage today at 4PM EST, which will bring the server down again. I'll try to get it up and running right after the power comes back.

Power Outages (Continued)
May 19, 2009
Looks like the power is going to be out until tomorrow morning with another outage tomorrow afternoon. I'll post more information as we know about it.

Post by **Labbie** » Wed May 20, 2009 8:07 pm

I guess the power outage finally started.

Post by **Labbie** » Wed May 20, 2009 8:25 pm

The web site is back up, but the feeder isn't running so no reporting and no downloads.

CUDA Application Update
May 20, 2009
Looks like I've finally gotten the CUDA application working. I'm in the process of cleaning up the code, and it should be available for you to play around with tonight. It's my first crack at a CUDA application, so it's a bit rough, but currently it's crunching the current stripe 82 WUs in around a minute using a GeForce 9600M GT. I'm sure there's quite a bit more optimization we can to do get it running even faster, as this is the first version and not optimized at all. Part of the reason this has taken so long was that I was doing quite a bit of testing comparing double and single precision math on the GPU. I've come up with some schemes that will allow us to use older graphics cards which don't support double precision math (like the GeForce I've been using); which should let a lot more of our users be able to use the GPU application. More news later when I post the code.

CUDA Application Alpha Release
May 21, 2009
I've released a preliminary version of the CUDA application in the code release directory. For more detail, there's a forum post here. This should run on the same test samples, however I'm having some issues getting a working makefile/build script using both BOINC and the CUDA libraries, so if anyone has some knowledge about how to do this it would be really appreciated.

CUDA Release v0.02
May 21, 2009
I missed a couple files in the previous release, so theres a v0.02 in the code release directory now.

If you're interested in the gory details & discussion, see the threads below.

24 May 2009 AEST:

I updated another version of the GPU code. It should have the evaluation directory now.

Post by **Gavin Shaw** » Tue May 26, 2009 1:40 am

26 May 2009 AEST:

I've updated v0.04 to the code release directory. This should work correctly with the compile script. The next steps on our to-do list are getting checkpointing working correctly for it (i'm pretty sure its not working), and compile time specified single or double floating point precision. In the next couple days I should get the milkyway_gpu forums up and running and some test work units available.

Post by **Gavin Shaw** » Mon Jun 01, 2009 1:40 pm

01 Jun 2009 AEST:

I've updated the code to v0.05 and its in the code release directory. I've combined the linux and osx makefiles into a single makefile, which can also compile the GPU applications. I've included a new (faster) kernel with this release as well. As always, the new code is for discussion in the following forum post and I've also started a thread for makefile discussion.

Post by **Labbie** » Mon Jun 01, 2009 1:44 pm

You're up late Gavin.

(aren't you? I get confused when it's more than about 6 hours difference).

Post by **Gavin Shaw** » Tue Jun 02, 2009 1:45 am

02 Jun 2009 AEST:

Looks like the gpu code release was missing yet another file. I've updated the v0.05 code and it really should work this time :)

I've increased the minimum sendwork time server side to 1 minute (this might be a bit high for some of our GPU clients so if it is let me know). I'm hoping this should increase work availability for everyone, so let me know how it works.

---------------------------------------------------------------

Yeah I was up late. Just before midnight when I posted that. Another 15 minutes or so and I would have had to put it down as the 2nd...

03 Jun 2009 AEST:

I broke the server doing some updates to get our new astronomers running their new searches. It should be back up shortly.

Looks like I fixed the problem. Things should hopefully be running smoothly again.

Here is a post relating to the new ps_sgr_208_* runs you may have been seeing and the Sagittarius Geometry that makes them different. ( http://milkyway.cs.rpi.edu/milkyway/for ... php?id=881 )

Post by **Labbie** » Fri Jun 05, 2009 7:17 pm

If you're using the current ATI app, you need to update it so your ATI card can run the "_3s_" WUs. The new vesion is 0.19f.

Link here: http://www.file-upload.net/download-168 ... I.zip.html

The new version reports GPU or wall time instead of CPU time, a nice change.

Post by **Gavin Shaw** » Tue Jun 09, 2009 11:13 pm

10 Jun 2009 AEST:

I made a little update to the search progress forum thread. You can now see how the searches are progressing here.

11 Jun 2009 AEST:

Nate finished up his PhD thesis and we've made it available here. Its also in our publications section. Thanks everyone for your help!

If you look below the news, the plots describing the progress of the different searches we're running is now on the main page. They're updated every five minutes.

Anyone who has taken a break from MW because of the not getting wu's. They have been back to 100% in sending out wu's for the last 24 hours or so. Just wanted to let you all know.

LMAO. I had about the same thought.

Well and I wanted to make sure to give it some more time and make sure it was working first.

Turn off my scripts last night. And they seem to have kept busy all night.
