Random " % complete" ??

[markg]

i just started getting what seems to be a random % complete message; see pic below. is this a problem? what if anything should i do?

thanks.

One thing you haven't told us is which version of Prime95 you are using but on a wild guess it is 25.x. Running two instances of factoring the same number on a pentium 4 would probably give similar results. Try giving a bit more info when asking that is pertinent to the question at hand.

i am using the current version, 24.14
if i was using anything OTHER than the current version, i would have mentioned it.

now that you know what version it is, and that i am not running two instances of factoring the same number, any ideas of whats wrong?

Nelson is just trying to help and since your first inquiry was not very informative...

The % complete numbers are not completely random : one part of them progress from 32,29% to 35,14%, the other from 38,39% to 41,38%...

Both progressed by a similar amount. The time interval between screen output seems to fluctuate quite a lot.

That interval depends on the number of iterations you set int the adhoc menu of Prime95 (Options / Preferences / Iterations between screen outputs) What is your setting there ?

Are you running heavy programs at the same time ? Is it a hyperthreaded machine ? Are you running more than one instance of Prime95 ? What happenned when the low numbers (32,29% to 35,14% and onwards) reached the starting points of the high numbers (38,39%) ?

Those are all questions that come to my mind.

It is a strange behaviour indeed...

Thanks Kubik(CZ),

That was what made me think it might be 25.x even though the window looked like 24.x. it still looks like 2 instances are running in the same window and on a hyperthreaded machine I don't know how 24.14 would do that unless the Ax option was being used, when I tried that I had two instances of Prime 95 with separate windows. Iteration speeds were comparable though.

P.S. might just try stopping so that interim files are saved and exit. Then look in Prime95 directory and check how many versions of Px00000 and qx00000 are present more than one of each is a sure indicator of something buggy. if only the two are there restart and see if the behavior continues.

everything was set to the default except user information and primenet options.

specifically; iterations is set to 10000 (default)
there is only one m and one p file
not running heavy programs; in fact this is the ONLY program running other than virus etc. background stuff
it is not hyperthreaded; 5 year old machine.
there seems to be two sets of numbers running PLUS another seemingly random numbers; one set in the 80's, one in the 90's, and a few turned up in the mid 70's (which seemingly already completed before it hit the 80s).

also, the time to complete the iterations seem strange; one string is high, the other low.

i figured i would let it run a bit and see if it finishes off, but it makes little sense. the other machines work fine.

Gosh Mark,

I'm as stumped as you are. Is this by any chance your T40p mentioned in another thread actually the only important thing is why two processes at the same time. They are definintely factoring the same number. That still doesn't explain two instances and/or the wide discrepancy in timing.

There appear to be at least two cores in operation which doesn't make sense. AFAIK ver 24.14 must be started twice to get to simultaneous operation with the affinity parameter A- to define which core to use. The only other explanation with one core would be that one test stops while the other one takes over but that wouldn't account for outputs at exactly the same time even as much as 60 seconds apart.

Starting a second Prime95 instance results with a second tray icon and two separate windows. Even at that I would expect timings on two cores on the same number to be very similar if not exactly the same. One instance appears about to end so maybe it will correct itself but that may require some input from Prime95 himself. I can't figure out how to reproduce this situation with the current information. ???does worktodo.ini have two jobs or more in it or two with the same number or any thing so bizarre.

could you give a screen shot of Procexp or task manager I guess we'd need the processes tab with "Show processes from all users" box checked and window stretched vertically to show all active processes.

Mark,

It is a bit as if Prime95 was working from two start points at the same time in one instance. Did you try Menu / Test / Status to see the estimated endtime ? I think that exponent is to near to completion. Once it is finished, if it finishes at all, I Would save the result.txt, prime.log an wortodo.ini files. Remove all files, uninstall and reinstal the software. If you keep the local.ini and prime.ini I presume they hold the key to the explanation. You could post them here (if you whish you can remove the password from prime.ini : the line starting with "UserPWD=")

Mark,

a real puzzle!

Are any files in prime95's folder readonly or with permissions that would stop prime95 writing to them? Just a thought - not sure if that would cause what you're seeing.

After you open prime95's window to see progress, is there indeed only one instance of prime95 in task manager?

I ask this because a few months ago I saw some occasional odd behaviour on a WinXP machine. Prime95 was starting as a service. Occasionally when I opened its window, a second instance would appear in task manager, with ~0% cpu. Using prime95's menu to exit would close the window & remove the new instance but leave the first running. When I killed the first instance from task manager, not only did it not save, but I found it had not saved any progress since the machine started...

I have no idea what caused it. It was only a few times, and I have not seen it recently, and I've been checking!

[markg]

only one instance running; i had checked this.

and this was the same machine i had an issue with described on another thread; i deinstalled/reinstalled EVERYTHING; ie all new options files etc., then selected factoring only under configure primenet (the machine is kind of slow, so i figured this was better work)

the factoring (the one at issue) finished ok (according to the results file, but didnt give me credit on the primenet status page), started a new factor, found a factor almost immediately (did give me credit for this one), then started yet another which it is working on now.

here is the results page: (i xxxx out any personal data)

I see one funny item in your local.ini :
Affinity=99
You can remove that line.

Not getting credit for your exponent 48486617 is strange... You can check if your result shows up on the V5 server in the comming days : http://v5www.mersenne.org/report_fac...99&B1=Get+Data

Since you are using Prime95 v24.14 I don't think George Woltman will be interested in debugging what happened.
