Gamma ray pulsar not for your computer

Hi!
I would like to bring back an adittional dual GPU Cruncher to Einstein, but (i already detattached it), brings a error message like:
Gamma-Ray binary search #1 on GPUs is not available for your type of computer.
Its the computer with boinc1 in its name (sry forgot to copy the hostlink to post it here). But i get this message on boinc4 too. But boinc1 is more important. Both has a mixture of 5xx cards from 560ti, 570gtx, and 580gtx.
Why does the system shows me this message? Was there any major changes on driver requierements, or are gpu minimum is 6xx now or something?
Thanks for any help ^^

The computer you linked to

The computer you linked to has Windows XP as the OS. Can you get a suitable driver for Windows XP??
GPU tasks these days don't use CUDA, they need OpenCL. The GPUs would have that capability but you need a driver that supports it. Take a look at the BOINC startup messages and see if the OpenCL capability of your GPUs is being detected and reported. If not, you don't have a suitable driver installed and that could be why the scheduler wont send you any tasks.
If you're in doubt, just post the BOINC startup messages.
Cheers,
Gary.
Drivers are 364.xx so new

Drivers are 364.xx so new enough for anything like OpenCL and so.
Like i said they done Einstein some months ago. So a major change must be happend in this time. Drivers minimum, OpenCL1.1 Support on HW side, 6xx GPU minimum, 64bit minimum, ATI only cos OpenCL performance, Win7 or higher, anything like that ^^

It's not really the driver version - more whether or not the OpenCL compute libs are also installed. I don't use Windows at all so I have no experience but there have been comments about missing libs from Windows supplied driver versions. That's why I mentioned the startup messages. Can you confirm that the OpenCL capability is being fully detected in the BOINC startup messages?
If you look at the scheduler log for you host's lstest contact, it seems to show that only CUDA work is being requested. There is no mention of checking for the FGRPB1G plan class. Are you sure your preferences are set up correctly to request that type of work?
You didn't actually say how long it has been since you last ran Einstein FGRPB1G GPU tasks. I suspect you may be referring back to a time when there were BRP4/BRP6 GPU tasks with CUDA apps. There was a big change then in going from CUDA to OpenCL for the big change from searching for radio pulsars to searching for gamma ray pulsars using GPUs.
There hasn't been any recent significant change in the FGRPB1G app. I have run a GTX 550Ti with FGRPB1G apps under Linux so I know there isn't a problem getting work for GTX 5xx GPUs. I don't currently run any 5xx or 6xx GPUs because of the low performance with the current apps. I do run a GTX 750Ti and it gives me about 50% of what I can get from an equivalently priced AMD GPU. Some time ago, I retired all 5xx and 6xx nvidia GPUs. There was talk about the possibility of a CUDA version of the app. If that were to eventuate, I would consider restarting the retired units.

mhm thx, i though they were

mhm thx, i though they were openCL already. i restarted boinc on boinc1 and it tells me that it has OPENCL1.1 compatibility on both GPUs. So that seems not the issue or it uses more then 1.1 and the cards cannot run them.
The work profile allows all work that is available on gpu.

GPU-Z program will tell you

GPU-Z program will tell you the Compute capability along with if the card/driver can run CUDA/OpenCL.
OK, I think I've worked out

OK, I think I've worked out what the issue must be. I hadn't noticed previously that your hosts are running a 32bit version of Windows XP. If you look at the current applications page for the FGRPB1G GPU applications, you will see that the required OS is 64 bit. I've been running 64bit for several years so didn't know there was no 32bit app.
I mentioned previously that the scheduler logs didn't mention the FGRPB1G plan class. I looked at the latest logs and also noticed that there was a comment (it would have been there last time) that said
no app version available: APP#40 (hsgamma_FGRPB1G) PLATFORM#2 (windows_intelx86) min_version 0and this time I noticed the windows_intelx86 platform. So, all along, the scheduler was advising there is no app for a 32bit platform. I should have read the log more carefully, sorry.
Cheers,
Gary.
Ohhhhh your right. Thx! thats
)
Ohhhhh your right. Thx! thats bad :/ these are dedicated crunchers, so its a bit hard to port them to a 64bit os. I will see what i can do. Thx thx thx!!!!!
