1) Message boards : Generalized Fermat Prime Search : Invalid units (Message 109889)
Posted 2030 days ago by Jason
And this is now done. The fifth result matched the second result. The other three results were incorrect.

Thank you for monitoring this, Michael - sorry to take up your time. I've never had a unit declared invalid before. I've had them fail to complete, but never had one complete and then fail validation. I'll keep an eye on things in the hope of avoiding recurrence.

3) Message boards : Generalized Fermat Prime Search : Not running on 32-bit XP (Message 77932)

Did the previous versions of Genefer (3.1.2-x) work for you on XP? Our intention is that the apps should work.

You can download these from the directory:


If it does, you can temporarily use those with app_info. We do have new GFN apps in the pipeline. We'll make sure those work on XP.


Yes, the previous versions,, & all run on my machine, provided they're supplemented by & The CUDA versions bench faster than the OCL versions.

Please could I ask you, Iain (or anybody) for help with the app_info.xml to run the CUDA 2.12 versions of Genefer, whilst leaving all the other x86 32-bit & CUDA subprojects intact?

(Iain - I've replied to your PM)

All the latest Genefer CUDA or OCL codes fail on my 32-bit XP machine; When BOINC tries to run them, the result is "couldn't start app: CreateProcess() failed - (unknown error)". XP reports these files not to be valid Win32 applications:

I didn't see anything in the guidance that the latest versions would be dropping support for 32-bit XP; has this now happened? Or is there something else I'm missing?
GPU is an NVidia GTS450, cc 2.1 - it used to work fine before the latest update.
