Hi, Noticed that my GPU's are sitting there and doing nothing...

I have 2 ATI Radeon HD 3800 (512MB) cards with crossfire enabled and it is not receiving any tasks.

Im running the following projects.
MilkyWay@home, LHC@home & SETI@home

I have been watching the projects to see if it gets any new taks the next time around but it doesnt.

The log in states:

- Requesting new tasks for ATI.
- Scheduler request completed. got 0 new tasks.

The SETI project under properties states.
AMD/ATI GPU work fetch deferred for 23:59:17

By BOINC Preferences is setup to "Use GPU while computer is in use"

Is it that the cards are to old? or whats going on?

ATI Radeon HD 3800 do not support OpenCL
http://developer.amd.com/tools-and-sdks/heterogeneous-computing/amd-accelerated-parallel-processing-app-sdk/system-requirements-driver-compatibility/

http://www.khronos.org/conformance/adopters/conformant-products#opencl


ATI OpenCL support is needed for SETI@home apps to run on ATI GPU:
http://setiathome.berkeley.edu/apps.php


Edit:
There is a possibility to use part (~20%) of this GPU to do astropulse_v6 tasks but it involves installing 3rd party apps:

"AstroPulse Brook+ (also known as HybridAP) application is intended to process SETI@home AstroPulse v6 tasks on AMD/ATi HD2xxx, HD3xxx and pre-APU onboard ATi GPUs.
It uses GPU as coprocessor to speedup FFA part of AstroPulse algorithm and uses CPU for all other parts.
For effective GPU usage it's recommended to run few app instances simultaneously.

I could not find the HybridAP download.

I found the download location at lunatics.kwsn.net but if i click on the link nothing happens. - page just flashes at me...

i figured it was cause i wasnt registered. I tried to register and it tells me the registrations are currently disabled.

Read "Lunatics Windows Installer v0.41 Release Notes"
http://setiathome.berkeley.edu/forum_thread.php?id=71866&postid=1375941#1375941

In the installer you have to select all apps that you need/use, not only the Brook/HybridAP
