Well CUDA works for me :-)
Might have a few bugs, need to reboot once in a while..
Overall it works..
So thx to Raistmer and everyone else helping fix the CUDA thingy

Elderberries are nice, especially elderberry wine. Mark, you need new cat nip, or have you been drinking to much again?

I'm running a Q6700 with an Nvidia 8400GS. I use the Alex Kahn optimized client. Today I Converted it to CUDA. BOINC recognized it and I presume is using it, although I can't tell by looking Processes in Task Manager. I also can't tell by the time per workunit. Seems to be running at about the same speed. What's up with this?

Nobody knows what's up with this............exactly the problem.........if this had been sorted in beta the way is should have been.........no problem here.

But I know why it was not so............meow. You will all have to ask the devs......good luck and good night..........see the flick..........'bout the same thing going on here.

The work re-issue rate must be extraordinary. I see a lot of crunchers with hundreds of aborted, detached, and errored out work that must be re-issued.

I agree with you Mark. CUDA may be working in the near future but in it's present form it should never had been released. Simply too many errors.

My main point.......have it work or get it the f outta here..........

I have gotten a lotta crap personally..........

The app sucks.......
The way it was brought outta beta sucks.......
The lack of addressing the concurrent issues sucks......

And the lack of truth surrrounding why sucks...........


Why not come clean, folks??????? Is it that hard to admit a mistake?? Can you hear me now????????????

When i do crunch with CUDA it's fine. The errors are me ****ing around. It is faster, though with the optimized AP apps things are clearly moving forward. Things will work in about 18 months.

Although all the points you have made mark have been perfectly valid.

That will be the one at `top hosts #21` that I spotted going sonic boom past me,
was at #178
Tried the combined MB AP optimised app and things went poop,
back on AK v8 MB only now.
Its a oc Q6600 for those that want to know.

I can quite understand how Mark must feel. As a former engineer, I'm far from happy with what may have passed as QC for CUDA - lots of things just don't make sense. Mark may be a friend and a fellow 'Kitty Person', but that does not mean I have to agree with him! Maybe it is me being 'British' which makes me 'stick up' for him, maybe not. I see a guy who is passionate about what he is doing and wants to see it done properly. Only people who have no feelings towards something, can be dispassionate and unmoved. Mark, quire clearly believes in what he is doing (never mind the outlay of time and equipment) and expresses himself very passionately. I would, too. For Heaven's sake, cut the guy a little slack (as US Marines used to say at RAF St Mawgan - and still do, elsewhere).

Mark,

Are you seriously saying that it's the project's fault because someone is using Alex's optimized application with an APP_INFO.XML file?

SETI@Home is responsible for the override feature through APP_INFO.XML that prevents BOINC from downloading and using the CUDA-enabled science app??

I haven't asked "nobody" specifically, but it seems IOTTMCO to me. As long as he's told BOINC he wants to run AK and not to update, BOINC will not even try CUDA on this machine.

Sorry for the rant.

Mark,

I'm not bashing CUDA precisely because I don't have all the facts.

From what I understand from Matt's post CUDA is about three percent of all work returned.

If we assume that CUDA never validates against the CPU app, and that there is a 0.03*0.03 chance (0.0009, or 0.09%) that two CUDAs will pair up, then the odds of an invalid CUDA result hitting the database is less than 1 in 10,000.

The third result has a 97% chance of going to the CPU app. so two CPU apps are very likely to pair up and validate.

... but when CPU and CUDA do not "validate" what that really means is that the results are different. It does not mean that they're not valid.

In another post, Matt says they've found the problem in the validator, and it sounds like they're going to be able to go back to the "invalid" CUDAs and revalidate them.

In other words, we may be a little bit premature in bashing CUDA.

Others have pointed out work in beta that did validate. Someone else could track them down and report if they wish.

It is a well-known saying that "Nobody notices when things go right" -- we have to remember that the people who are running CUDA successfully have no reason to complain in the forums. We really can't draw any statistical conclusions from our discussions here because our sample is "self-selected."

We're probably better off than reports suggest.

Im going to try it when I get a card. Put it on my second machine and see wwhat it does. Actually I've got my cruncher running about as good as can be, so things get boreing. This reminds me of when we switched over from classic, a new boinc version about 2 or 3 times a week.I'm sure the project thinks eventually it will be fine. But I don't like my results getting skewed one way or the other. But time will tell!
