Your cpu's graphics(HD 2500) are comparable to my 8600GTS. I don't run anything on it as it is so slow.
The next generation(HD 4000) has much better performance.
Mine is single precision only. I assume that yours has double precision support.
Almost all of the gpus NVidia sells currently have higher performance.

Thanks Henry, the problem is that actually I have no Nvidia GPU on my PCs... :sad:

I just posted the [URL="http://mersenneforum.org/mfakto/mfakto-0.14pre4/mfakto-0.14pre4-Linux.tgz"]Linux version[/URL], basically untested (will test tomorrow).

But you could give it a try. "mfakto-pi" is the "PerformanceInfo" version that measures each kernel's run time. _x32 and _x64 are the normal, optimized versions.

Try playing around with these mfakto.ini parameters to see if any combination works:
VectorSize
SieveOnGPU
GPUType

Depending on the errors you'll encounter, other settings may be needed too.

I agree that the GIMPS contribution in terms of GHz-days will be rather limited. But isn't getting the achievement "First to run mfakto on Intel GPU" something to be proud of :smile: ? I think we're closing in on it ...

[QUOTE=ET_;369998]Here is my OpenCL system:

Oh, I just noticed, that the OpenCL system did not yet recognize your GPU. What is listed here, is the CPU (I'm quite certain that mfakto will run on that).

Making the GPU show up in the list may need additional effort (drivers/BIOS/hacks/whatever) ... that is something that the Intel forums should be able to provide help for.

Last I looked, Intel only has Windows drivers for OpenCL support. The forums indicated Linux support was not on the horizon.

Hmm, I did not think any company could still run that strategy ...

Well, ET_, this means your system won't run mfakto on the Intel GPU anytime soon ...

Thank you for your effort and hints :smile:

I'll stay on doublemersennes project for now.

Did anyone try the 0.14pre4 version on Intel HD yet (obviously only on win)? Did anything change compared to 0.13?

Is anyone besides kracker testing 0.14pre4 at all?

I am trying it and it seems to be working.

Some lagging on the screen when running faster assignments. The screen froze for half a second every update to the console. The strange thing is that it seems to have disappeared when I changed "PrintMode=1" to avoid scrolling.
It could be some other thing too as this is the first time I'm running mfakto under linux.
