Modified SETI MB CUDA + opt AP package for full GPU utilization

[Raistmer]

Everytime a task gets stuck and my script notice that it will do a copy
I've a bunch of them now ^^
Omgh , could someone attach stock app 6.0.7 please.
Ive a full cache ...

From a comment somewhere in the BOINC sources, his board is a Quadro FX 3700.

That card has the same number of shaders (112) as my 9800GT (but costs six times as much - hehe).

I can't find a clock speed for it - but if I plug the shader clock for the 9800GT (1500 MHz) into the formula, I get 48 GFLOPS: seems like the right ballpark.

If they're going to set the limit 25% above a 9800GT, then GPU crunching is dead until the next generation of hardware.

I've been discussing CUDA-Z performance measurement off-line with Maik. Here is my card's report - it seems to be (still - just re-tested) just fast enough to pass SETI Beta's - and hence David Anderson's - presumed speed test: I get Beta v6.07 allocated automatically.

I think you're looking at Integer arithmetic.  Take a look at single precision, which is what we use for the majority of computation. (You've got a little headroom)

I like device to device memory copy speed, really

Yet Raistmer's 9600GSO was too slow. I was hoping a few ective users could post comparisons (maybe just the floats, not the whole graphic), and whether they can get work from Beta, so we could work out where the cutoff came. People are already asking questions on the SETI Main board.

Good idea, repost CUDA-Z link here, please... It will simplify comparison...

OOps, it shown on picture, sorry

hello all

i have new version APP

@slawek, your gfx-driver-version?
and what app-version are you using !? (Triplet count:  31 found at your results ...)

And can you get work from SETI at the moment, without an app_info.xml?

As you all know already My host can't get 6.07 on beta w/o app_info.xml

And yet both your float and int speeds are only about 5% lower than mine - I think we have our cut-off.

   Ok Firstly, info special for you - there is new V5b build - it does VLAR autokill + decrease it's own priority class - you could try it - it should be much less laggy than all my prev builds.
And about 6.07 - see this conversations from this post:

Runs okay on 9600GSO? , any more driver crashes?
