There was a thread a while back about an OpenCL AP app for Nvidia GPU's.

This subject has gone very quiet.

What is the current state of play concerning this app ? Did it make it into the real world ? If so, where can I download it ?

Inclusion of OpenCL for NVidia applications into the Lunatics installer are subject to playing nicely with the newest recommended driver.

It is available as a beta app from Lunatics.
Current revision r540 - please note that development has focused on the changes needed for AP v6. You can use r540 for v505 work by using the -v505 commandline switch.

Please note that the application is exhibiting high CPU usage with CUDA 4 (270.x+) drivers.

i wish so much if someone can make a good tuto on that.

a 101 tutorial for noobs like ME.

A good tutorial on what?

on what we need to do to get our Nvidia (mine is a GTX-480) crunching these AP.

Possibly 266.58 for the driver, whether 266.58 supports the GTX480, I don't know. I run 275.50 and It does good on MB with 2 GTX295 cards, but not on AP cause of the 270+ drivers and the app not getting along(crashes the driver over and over).

i have : 285.62-desktop-win7-winvista-64bit-international-whql
and i quite need it cause it s also my awesome gaming machine.

Under those circumstances, I would highly recommend not using the AP for NV app, at least until the driver-app compatibility issues are completely resolved (at which point it would be distributed as part of the installer).

serious ? awwww /cry

and whats about the new beta ones ? GeForce 295.51 Driver

Keep your eye on Statistics - Top Computers, if something is worth using most will be using it, if there is problems with something or its not worth using then most will leave well alone.

alright , i ll test.

i ve downloaded : 266.58_desktop_win7_winvista_64bit_english_whql.exe and deleted my old drivers and installed that one.

i ve downloaded from lunatic that exec APv6r540_NV and i ve copy/pasted it in my BOINC\projects\setiathome.berkeley.edu\ dir

now what i need to do ?

Edit your app_info and add an NV AP Section making sure you use the -v505 cmdline parameter or none of your results will match.

<app>

        <coproc>

            <count>1</count>
        </coproc>

            <copy_file/>
        </file_ref>
    </app_version>

The above is what you need to add to your app_info, make sure you add it before your </app_info> closing tag.

Make Sure you use the -v505 cmdline parameter or none of your results will match.

Claggy

but it doesnt tell me what to do. say like i was an 8 years old child :) explain to me :) please :)

Take a plain editor (e.g. notepad) open app_info.xml
paste the AP entry (see below) in at the end - but before the </app_info> tag. Save (make sure you are saving as 'all files' and not as 'txt file')
sadly indentation gets lost on posting here.

edit: or take Claggy's :D minor differences in the commandline settings. mine are suitable for small GPUs.

The difference is very small but vital... the sign in dechirping reversed.
It leads to complete results incompatibility between V5.05 and V6 "binary" wise.
But from scientific point of view nothing changed.

When I was crunching with my 2 460 it got HOTTTTT

A Linux version, please!

Please note that the application is exhibiting high CPU usage with CUDA 4 (270.x+) drivers.

See what Matt Arsenault has done here.
Im my case, after some tuning, the CPU usage was reduced from 150% to about 50%. Nice!

I assume you want a GPU Linux version? Unless you can pull a competent coder out of your hat, Lunatics currently just doesn't have the manpower. Everybody on the team works entirely voluntary. I can count the active coders on one hand. And they are almost all focused more or less on one particular app (or set of apps).
Currently they are all working very hard on getting the apps for MB V7 ready.
As far as I'm aware a Linux OpenCL AP app is in very early alpha, but hasn't been worked on for some time. If you are lucky, when the MB app is out, development might focus on AP again.

The biggest problem with Linux apps as I see it - lack of testers.
Urs does Linux build very fast after I commit new code and do Windows build,but he restricted with 1-2 alpha testers so app qualified as alpha because no one can prove it works anywhere else.
So if someone want Linux binaries be ready to test them....

From my experiences with various nix systems most users of such systems should be prepared to be alpha testers for pretty much anything.
