The old or the new app makes no difference for my GTS450eco (device 'GeForce GTS 450', version 'OpenCL 1.1 CUDA' and driver '352.63').

A new version of "geneferocl4" is available (32-bit binary for windows) at https://www.assembla.com/spaces/genefer/subversion/source/HEAD/trunk/bin/windows (for benchmarking).

It is faster than the previous version but the counterpoint is that bMax is one-half OCL3 limit (and about twice OCL limit).

I'm working on my laptop and this version is not tested. On a GeForce 740M, OCL4 is now about as fast as OCL.

9) Message boards : Generalized Fermat Prime Search : GFN short/WR both low GPU usage (Message 86892)
Posted 1702 days ago by Profile rroonnaallddProject donor
So I put the app_config.xml in use and now want to disable or remove it. I renamed it but am still getting dual GPU jobs running for some reason and even rebooted. I'm sure I'm missing something really small but other than deleting the file is there anything else I need to do? I also thought maybe there was another copy somewhere but it's only in the folder Gary mentioned.

Let all your jobs finish, detach from PrimeGrid and reattach. That's how I do it.


Thanks. Will try that in the future. I removed and reinstalled boinc but your solution is better.

Cheers Rick

Does let all jobs finish, rename the xml file and restart boinc not work?
10) Message boards : Generalized Fermat Prime Search : Genefer 3.2.8 testing (Message 86770)
Posted 1715 days ago by Profile rroonnaallddProject donor
One common difficulty with all builds I have used are tha they require glibc 2.14 on linux. Scientific/Centos 6/some other REHL distros only support 2.12 as of now, what would you guys recommend when it comes to this?

I have no idea how to solve this. Recompiling the apps on your side is no solution because then you have to use the app_info.xml-construct. The last time i got this problem, i simply upgraded my entire linux installation and according to Glibc 2.14 needed is the best solution the upgrade to CentOS7.
This is all what i can say for the moment.
