a simple request

[rainchill]

Hey Folks,

I've used prime95 off and on for about six years and think its going to be my distributed computing program of choice from now on. Anyway, I like to keep my prime95 window uncluttered so I have it report its progress in iterations of 3 million. This is good since I leave my computer on 24/7 but sucks because the closer I get to 100% the more anticipation I have of it possibly being prime.

So, I'd like to see a feature added where not only can it be specified how many iterations to wait to update the program/log files but to put the iterations and % complete in the title bar which can have their own rules of how often to update. that way I can more accurately check the progress and not have everything look too messy.

Thats all I got, thanks for hearing me out.

The way the LL test works, you can be at 99.99% done, but it doesn't make it any more likely to be prime than when it's 0.01% done. It must be 100% done before it knows anything.

For more info on LL test:

I get anticipation too when my computer gets close to finishing one, but from the way you said it I think you misunderstood what the LL test does.

As for your actual suggestion, I think it's a good idea, and I don't know of any way to do it currently. Maybe it could just work that each time 0.01% of it is done (or however much is the least shown...possibly with this amount being adjustable), it would automatically update the % and iterations in the title bar.

I think you missed the point of the post. I don't think rainchil was stating that the closer to the end of the LL test the higher the probablitlty of it being prime. He was simply stating that his anticipation is at a higher probability

Congratulations. After 10 years in operation it really is pretty hard to come up with a genuinely new feature request. You did. I'll add it to my wish list, but I don't hold out too much hope for it being implemented.

Yeah, I figured that might be it while I was writing, which is why I put this in it:

Hey Folks. Thanks for your kind words Mr. Prime95.

Yes, I know that the % complete has absolutely no correlation to the probability of being prime. Bundu interpreted my post correctly.

Mini-Geek, just to clarify, my request is in reference to the primality test phase of the process, which takes the longest. In my case I have the program update the log every 3,000,000 iterations and that takes about 2.5 days on my rig. (AMD 64 X2 6000+ 2GB DDR2 800 ram.) I think it would be cool to have options for the title bar to update independently of the log with settings for 'update every xx.xxxx% iterations' & 'update every xxxxxxxx iterations.'

And yes, The closer I get to 100% the more anticipation I have of getting a prime. ;-))

Another 'simple request': adding a time stamp to every line that's written to the console instead of only adding time stamps to lines that indicate progress. Currently, lines about communication with the server don't have time stamps, and I think it looks neater if they do.

Regarding Windows Prime95:

In the past we've asked for a plain text log file that duplicates the screen output.

Once we have the data in a plain text log file the options for what we can do with the data are nearly unlimited.
