The P-1 factoring CUDA program - Page 45

I noticed today that when my screen goes blank my iteration times triple. I am guessing that this is a known feature on windows. Is there an easy way around this?

Well, I only work in a TF environment so maybe that's the difference, but my TF rate increases slightly when my screen goes blank.

My best guess is under Power Options > Edit Plan Settings (for your specific power plan) > Advanced Power Options > PCI Express you might find something. All I have is the one option set to disabled so check that this is what you have also.

Otherwise, the fix is to set the display to always be on but turn it off yourself when you don't need it.

I've noticed there hasn't been any new code checked in since late 2013. Has development ceased, or are people still working on it behind the scenes?

Already off.

Are there any linux binaries around for P-1?

I tried compiling, but epic fails all around. I can only get latest environment, and that needs latest drivers which don't seem to work for me.

You use Windows? Linux? I can help with linux, but someone else will have to jump in if its windows.

Try this one: https://www.dropbox.com/s/mr0z8e9pbi...20.tar.gz?dl=0

It is compiled with cuda 5.5 for 64-bit linux.

Thank you heaps.

Much appreciated.

I'm running the code from the previous link on a g2.8xlarge instance on AWS. I'm getting approximately 25GHz-days/day P-1 per GPU.

Also, I'll note, I've found 2x factors.

Personally (at least for TF'ing) I find the cg1.4xlarge instances to be better value (in us-east-1d -- "Spot" often less than $0.14 an hour for two Titans).
