This cuda development is of course great. But there are probably some drawbacks, some of which have been noted on this board.

I have a couple of 'silly' questions about credits and cuda.

Will the credit be associated with the host-cpu or tallied separately, as a separate host perhaps?

If merged with the cpu, will the upgrade or change of the graphics board cause some sort of reset in the credit tallies? Right now on a system without a gpu, if I were to upgrade my cpu but nothing else, I think a new host is established and I can't merge them. Will that happen with the cuda subsystem, too?

Not silly questions at all.....
I was just pondering some of the same things....

Like whether the top 100 computers is gonna be able to differentiate between those running a Cuda card and those just running an honest cpu...

And what the daily quota for a rig with a Cuda card is gonna be....

And why the time and effort was expended on this development rather than on nitpicker and real time.....

And if the splitters cannot keep up with things reliably now, what is the increased WU demand from Cuda hosts gonna do.....

And is the increased speed of Cuda hosts gonna further screw the credit multiplier for the rest of us....

If I start running out of work for my rigs because of an increased load from Cuda crunching hosts.....there's gonna be trouble in kittyland.

I have to admit, i agree with Mark. Resources appear to be used for matters that could wait. There is still no official AstroPulse app for the Mac. Ntpckr has been talked about since i joined yet we have not seen much if any progress.

Now all of a sudden the GPU client comes out but only for windows with nVidia cards. Before anyone chimes in about the Cuda drivers, the ATi SDK has been around for a while as well. Folding@home have had both ATi and nVidia clients for some time.

Development to progress the project are great and most welcome, however when it ignores a large percentage of users, things need to be looked at. If the development continues along these line, I would imagine a lot of people will consider going elsewhere.

All of his other points need to be seriously addressed.

And only seven days since the first (and so far, only) CUDA application was put into testing at Beta - Windows only, Linux misses out as well as Mac.

From what I read, the app cannot yet even process the full AR range (VLAR seem to fail), and there are also problems with the required BOINC v6.4.5 client (released prematurely without adequate testing yesterday).

This is not ready for primetime. Thoroughly unscientific.

will i just got my main computer online after a hard drive got wipe nvm how i got some cuda wu's when i set it back up so the box is open good or back

Drivers for Linux are already out.. i have Dl them but not yet compiled new cores.. since im a bit rusty with linux still lol
you worry abt credits.. i see it as a good way to get this big chunks of AP done in decent time.. (i work at sea and don't want to leave unfinished work here as i go to irl work .)

well easyest way to deal with stats is prolly just to see them as additional cores.. board already calulates stats with included info regarding numers of cores in computer..

I may be totally wrong, but it is beginning to look like macs are starting to get dropped from the project. Might be time to move everything over to folding@home.

So much worry about credit. It's the last thing I think about. As I see it, the association with Nvidia can do nothing but help the sciences. Boinc user totals at Seti and across all the projects has flatlined. As many user leave as new users arrive. The extra publicity from Nvidia can only benefit all the projects. Also, there is no knowing what financial benefit this association might have for Boinc and the fund starved projects like Seti.

---

Boinc V7.2.42
Win7 i5 3.33G 4GB, GTX470

Macs make up 5% of the total computers..(Worldwide that is) I honestly wouldn't worry about them as a high priority for a client.


Sure we could make it for ATI and I hope that they do.. however im a Nvdia user and have 2 nice rigs, which to me is going to let me do more science..

If all this comes down to a whine bout credits.. its not a valid argument.

How many people would still be here if all of a sudden no credit was awarded for Seti..

I bet the majority of seti crunchers, the part timers who like the screen saver wouldn't leave or care


Crunching for me is just a fun hobby to be in, the science, the computers.. everything, when we look at it like a job, or something more serious then something we enjoy.. wheres the fun in that?

Dorsilfin, we may only make up 5% of users, we crunch a hell of a lot more data. Your attitude sums up exactly what is wrong with the development for seti.

It has nothing to do with credits, if that was the case I would have left a long time ago.

Hell I have XP on the Mac Pro, and I can easily upgrade the video card to the 8800, the fact is the the science is only fun when everyone is on a level playing field on an application front. Whch is clearly not the case.

---

With all things being equal..

Would you for the projects overall progress given the same resources to do 1 thing before another.

make a client for mac Astropulses
make a client for Nvidia GPU users

I dont claim to know what goes on behind the scenes with the Seti crew, but From a strictly numbers standpoint. It makes more sense to do something with the highest return first

Trust me, not saying its fair by anymeans for the dedicated mac crunchers, just that it makes more sense from an overall progress point of view

So in light of the announcement on the front page is Cuda now running here on the main SETI site or still at the beta site only?

---

Boinc....Boinc....Boinc....Boinc....

SETI@home Milestone from the future:

Just broke my highest RAC ever... now just over 450,000! All on a few GPU's!
Oh BTW - crossed the 1,000,000,000 milestone.... Still over 800 users above me though!

(Exaggerated - Just hoping to provide a bit of a seriousness break :)

- Luke.

Of course apps for Windows will be first, but it would be nice to actually see some evidence of a mac version especially for Astropulse.

I will go to where ever my equipment can be best used. and give the most benefit to science.

I think this issue is more because nVidia had a hand in helping the seti guys create the GPU app. That's why we didn't know about it until it was almost ready to launch. I believe F@H started out with nVidia as well and then ported to ATI probably for the same reasons.

Everything takes time and they go for the biggest impact first. Heck if OSX would run in a VM I bet more people could help with porting because a lot of people just don't own Macs.
