The only way to get your HD3850 crunching is to use a third-party application, and even then the only one that will work for your GPU is the "hybrid" app that uses the CPU for most calculations and the GPU for a few calculations on AstroPulse-type workunits only


OK, I think I understand that hybrid means Lunatics.
Which I'm running very happily.
And that's why GPU temp/load/fan run very low when other GPU-intesive projects are disabled.

Very incisive.

And very polite, thanks.

Summary.
It seems that I am now happily running SETI WU's using my GPU via Lunatics (only works with AstroPulse, very little GPU load) whilst other heavily-GPU intensive BOINC projects complete really quickly.

Sweet.

If I've got any of this wrong, please PM me.

Thanks very much for your reply.
In order for SETI to send work to a host, it must be identified and make a work request.
OK, I think I understand that.
If you were getting messages about "No usable GPUs found"
No, I have never had these messages since the HD3850 card was fitted.
and were not using the Lunatics optimized app
OK, I was not using the Lunatics optimized app
.
Where does that leave me. please?

Post:
The HD3850 can process SETI AstroPulse tasks
ummm does this mean that the original "ghost" aborted original non-Lunatics app SETI GPU tasks mentioned earlier WERE genuine, I wonder.
Please, don't make misleading statements.
Of course not. What good would that do anyone ... I'm here because something I tried didn't work as expected and need advice.
FWIW Personal insults are unwelcome on ANY forum irrespective of eminence.*
But you didn't quote one.
?
Every time SETI starts and a non-usable GPU is encountered SETI says so.
This is what the whole thing looks like:
Sorry, I get nothing like that.
Looks like you just like to make wrong assertions
*Please understand that when anyone makes an un-called-for judgement about my decision making ability etc then decides to makes it public without the courtesy to contact me, privately, beforehand I take deep offence.

Post:
I'm pretty sure the "No usable GPU found" message is a generic BOINC message
I was very careful to say ...
BOINC log SETI messages


you need to refer to that developer's release notes

Versus project messages hmm ...

Anyway, I'm over all this. I don't want to waste anyone's time any further.

The HD3850 cannot process SETI GPU tasks.
Period.
End of story ~~~ unless SETI sends GPU tasks for the HD3850 on the "sensitive" PC to process, which it might do, automatically, with no input from me.

Thanks, again, everyone for your valued feedback, time and effort replying to my original post here.

Thanks for the tip - I already run MW@H.
Finding the info you indicate is easy. SETI automatically checks the GPU and if it's unusable for processing SETI GPU tasks (precision/driver etc) it says so in the BOINC log SETI messages ... something like "No usable GPU found". FWIW the HD3850 passes the automatic SETI GPU check and all other projects recognise it, since no such messages appear in the log for other BOINC projects.
Maybe I have (again) got the wrong interpretation but that's what I've seen & understood prior to fitting the HD3850, specifically 3 other, very old cards AND a brand new HD4670 were all rejected because they were single-precision.
Aside:- this PC runs an AGP interface, althought I believe that the type of interface is irrelevant for GPU-intensive tasks.
HTH, Ray

I bought the HD3850 (512mb) because it has double precision that SETI requires for standard GPU tasks. That was my only reason for spending a LOT of money (and >4weeks' wait) on this card.
Also, I read somewhere on Tomshardware that it outperforms the previous card I had - a 1GB HD4670, single-precision - by about 5% in a summary of real-world situations.
If there is no pre-existing way to run SETI work on this card then I have misunderstood, and will contine non-SETI GPU work, probably using a card that costs 1/3rd of the price of the HD3850.
I doubt that HD3xxx, even with DP, was good investement ... especially for SETI.
It appears I have wasted everyone's time, here.

As before, I thank everyone for their close attention to detail and precision when replying.

I'm now running Lunatics Unified Win32 v0.38
AstroPulse v5.05 (ATI) Option ... ap_5.06_x86_win_SSE_BROOK_NO_DOUBLE_r453

All SETI tasks are now showing "Local: setiathome enhanced 6.03"
WU progress is better than normal, I think.

CPU usage is incredibly low, which is what I want - two processes are concurrently running, named AK_v8b_win_SSE_p3.exe @ 5%~20% of a Gallatin set to 10% CPU * both HT cores running. Normally SETI CPU tasks overload the 10% per-HT core limit … a LOT.
GPU AVERAGE values, nothing else running, via GPU-Z 0.5.4 are:-
GPU/Fan/Load
38.6C/33%/28%
(I run VDDC at 0.974 and a modified fan speed profile, set using ATI Tray Tools v1.7.9.1557.)

Is this all magic? I've let things run for 23 hours unattended.

FWIW When I started other BOINC GPU projects ...
~ Lunatic kept going even through 90%+ GPU load required by the other projects
~ As usual with tasks from other BOINC GPU projects all hell broke loose with fans & temperatures.

c:\temp\clinfo\clinfo.exe ... Run ... "cmd" .. enter, [to] open a command prompt.
Yep.

You'll get a lot of info displayed to screen etc.
Nope, I get an error message as follows:-

Microsoft Visual C++ Debug Library [window name]
Debug Error!
Program: ... clinfo.exe
This application has requested the Runtime to terminate in an unusual way.
Please contact the application's support team for more information.
(Press retry to debug the application)

When I press retry I'm dumped back into the CMD window with no other info.

a) ... you just got them mixed up? Yes - highly likely, on reflection as I've seen no further ATI GPU-only tasks from SETI for days now.
b) ... With that and a modification from Raistmer could run APs on your GPU ... OK, I'm game - what now?

Ray

PS ...
Granular description of my original issue:-

In Lunatics Unified Win32 v0.38 Setup
AstroPulse v5.05 (ATI) Option ... ap_5.06_x86_win_SSE_BROOK_NO_DOUBLE_r453 & will use extra CPU as well.
I interpreted the NO_DOUBLE as not using double precision during GPU tasks (the HD3850 is a double precision GPU) and that where double precision is required it will use the CPU instead. Which is not why I have just paid for a HD3850 (AGP) card to process SETI GPU tasks on this ancient PC.

Post:
WOW! Thanks so much.
I understood all that :-) and am truly impressed with the level of detail in the reply and the care in explaining the issue in the clear.
I will try out a non-sensitive PC as advised.
FWIW I'm confused about two things:- first, the (4, thanks) SETI tasks I thought were GPU tasks since I'm pretty sure they showed as ...ati14... and second that SETI recognises a usable GPU on that PC. Maybe I misunderstood both indicators?
FWIW2 I haven't received any similar "GPU" tasks automatically from SETI since my last post so I guess I must have misunderstood. Thanks very much, again.

Hi.
Yes.
a) I aborted those few tasks because they were sent (automatically? by SETI?) to a "sensitive" PC. I have tried to get more SETI GPU tasks on a less "sensitive" PC but no joy yet thanks to the regular SETI outage.
b) I promise I'm not running an optimise app because ... ummm see my original post :o)
c) nor an app of my own because ... I wouldn't know how to begin.

PS ...
I see nothing but aborted work from you
... which proves my point a) above? That is ... How could I possibly have aborted any running SETI GPU work that has been sent/received/started to process & then abort if it wasn't ermmm ... sent, received, processing started? Or maybe ... there's something out there ~ ~ ~
FWIW if I remember correctly, there were three SETI GPU taks received, each was about 116 hours duration but that's not important right now.

I've received a few GPU tasks automatically from SETI running under non-optimised app (who knows?) - will post here again when I have more data.

If the answer is yes then I will stop bothering brainiac and instead I will seek advice elsewhere to avoid clogging the SETI forum server :-)

... or else please, please keep it simple*.

Thanks, Ray

* NOT SIMPLE
For cards without OpenCL support (from HD2xxxx on) use the 'hybrid' r453
Astropulse application. NB this is a combined CPU/GPU application and will only
use the GPU for some of the calculations, while doing the rest on a CPU core.
Minimum driver version Catalyst 9.x


Eh? Why? Is it relevant to my question? How? Explain, please ...

I really want to understand these erudite replies but the more I ask the deeper the fog.

I don't need fog.

De-fogger ...

The HD3850 supports double precision.

Lunatics_Win32_v0.38_setup install refers to newer cards and also refers to support for older cards than HD4xxx WITHOUT double precision.

The question ... is there an optimised app for this older card that DOES support double precision? A direct link would be nice :-)

I truly appreciate the replies but none answer the question in a clear, simple way (sorry!).

E.g., have you tried
this zip
using an HD3850 - yes. What result did you get - I got gobblydygook.
You can look here for more information on the latest Lunatics installer.
I did but thanks for that.
I don't think it's necessary to be capable of double precision
Are you sure?

FWIW I've read every post on http://setiathome.berkeley.edu/forum_thread.php?id=55690

FWIW2 Imagine you are trying to do this without any prior knowledge of Lunatics and are trying to do this for the very first time ... err like me :-)

*FWIW my confusion arises from the phrase "... you're limited to ... using [the] old Hybrid AP app".
What EXACTLY does that mean?
To clarify:- there are multiple & conflicting/mutually exclusive choices during install - which is why I'm asking the question, I guess.
As I said ...
Lunatics_Win32_v0.38_setup install refers to newer cards and also refers to support for older cards than HD4xxx WITHOUT double precision.

The HD3850 supports double precision ... which is why I bought it after much research.
