MilkyWay@Home Heads Up

Post by **Megacruncher** » Mon Mar 30, 2009 12:28 am

The MW website is back up again & I see that peeps are getting credit again. I'd plugged an old 9600 into my test rig so I'll let it finish it's GPUGrid test WU before I put the 4850 back in again.

It's quite impressive that we managed over 658K yesterday in a day when we got next to nothing from our best paying project and only had 23hrs to crunch in!

I see the nVidia version is being worked on and there will be no GPU drop in credits when they have finished reworking GPU vs. CPU WU's.

And max. allowable WU's for GPU's will be increased. Whoo Hoo.

Nice.

SERVER LOAD!

Well I imagine it is a side effect of:-

Second, we're going to be doing a few server-side changes to how things are run, which should significantly help with workunit reporting and work availability. We'll be splitting MilkyWay@Home into two separate applications/backends, Milkyway regular and Milkyway GPU. This will allow us to keep current workunit sizes for non-GPU applications, while farming a lot more work out to the GPUs (so they need to contact the server less frequently).

We'll be doing different optimization methods on the regular Milkway and the GPU Milkyway so they'll both be doing equally valid research. In the next day or two I'll be posting the code that the application will be using for the GPU version. After testing to make sure that it's working correctly we'll swap to only awarding credit to the GPU applications for GPU milkyway (that way our servers wont be as bogged down, which will mean better work availability).

Also, before a credit firestorm erupts again, we have no plans to award less credit/work to the GPU applications, so you don't need to worry about that.

Hopefully it'll be worth waiting for. In the meanwhile I can get the square root of SFA from the project. If I could get the whole farm running it and CUDA is as generous as the ATI port then we will indeed have lift off.

For now we don't.

nVidia will not quite be as generous as ATI simply due to the number of double-precision FPU's between the 2 cards.

Now there is some FUD around how many of these Milkyway will actually need, but it will be anywhere from the same time to 5x longer depending on how many it does use. Seems ATI didn't skimp on the FPU's.

Like others I just wish I could keep the cards I have busy
