[quote=S485122;133819]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 : [URL]http://v5www.mersenne.org/report_factoring_effort/?exp_lo=48486617&exp_hi=&bits_lo=0&bits_hi=999&B1=Get+Data[/URL]

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

its been running fine since it finished the prior factor;
i removed the affinity line (must have been put there by the sw)
still no credit; not the end of the world, but it did show up in the status file, so i dont get this

[quote=markg;133764]
there is only one m and one p file
[/quote]
isn't that a bit unusual? i.e. factoring and LL is running at the same time?

(maybe not unusual if things are done according to load / day/ night time or other settings, but my machines always did one after the other ; I don't remember having had a p and an m file at the same time.)

PS: and since you have [SIZE=1]TwoBackupFiles=1, whenever there's a p*** there should be a q***. (not later than 30 mins after the p*** started existing)

:blush:yes I think that may have been my bad the context for the affinity
switch is -An not A-. A-1 would convert to 99 being the complement of 1
(if you add 1 to 99 the result is 0 with an overflow when your calculator
has a fixed number of 2 digits. Digital calculators just switch to floating
point notation so most people never see it.
The overflow as the result of a subtraction which is commonly used in
binary arithmetic is expected and not an error and adds to the sign bit
changing to 0 in binary resulting in a positive number and 1 without an
overflow resulting in a negative number. In the case of base 100, 99
is the largest number and -100 is the smallest that can be repesented in
some arbitrary Accumulator with 2 digits) Happens a lot with a digital
ohmmeter, just can't be used for arithmetic

:showoff:
.. 02 base 100 complement. 02 because the number is positive
. -01 base 100 complement. 99 because the number is negative
add
= 01 ......................... =(1)01 the overflowing 1 is lost but not
unexpected a test for overflow indicates we dont have to complement
the result to get back to the correct result.

.. 01 base 100 complement 01 because the number is positive
. -02 base 100 complement 98 because the number is negative
add
=-02 ....................... =(0)99 because there was no overflow it
must be complemented resulting in 100 -99 = 1 the negative result
. -01 :showoff:

A simpler way of looking at it would be just subtract 1 from 100 equals 99.

the process is simpler in binary but a programmer has to be careful to test
for invalid situations probably Prime95 didn't expect such an error to occur
and didn't put a check in for that or just dealt with it by setting the
number size to 2 digits not expecting a machine with more than 100 or
more likely 16 CPU's to be running his program. And guess who stepped
into that doo-doo yours truly who should have known better. I'm not sure
it was the cause of your problem because you had the problem prior to my
erroneous posting.

You can also use negative numbers in your memory settings and prime 95
will try to use all memory available except the specified negative amount.
Meaning that all other programms including the OS are expected to be
able to run within that much memory. helps keep the hard drive from
thrashing due to insufficient memory.

Information on start parameters and other settings can be found in the help window.

If you are interested on more information on Complement arithmetic
googling on "Two's Complement" comes directly to the wikipedia entry and
the wiki(hawaiian for quick/short)-pedia is an excellent source of
information but not always quick.

The above may be more information than you are interested in but may be
of some use to others looking in.

:tu:Glad the program is working correctly now. Are you looking at your
personal status page? or the overall status page? Your personal status
page will show as uncleared somewhere near the bottom until some preset
date when synchronisation is done. The overall status will probably
be updated at that time too.

How to get to your personal status page can be found on Prime Net
pagelink of mersenne.org

Affinity=99 has nothing to do with the problem. Affinity 99 means "run on any CPU" of a multi-core machine.

Two backup files only applies to LL testing. Trial factoring never generates a q file

im looking at both my personal status and the overall status.

it may be that im confused as to how this works; i have only been doing LL testing until recently, and each one of those shows up when completed.

however, i changed the (offending) laptop over to factoring, and originally thought that all results would show some record; it finished 4 factoring jobs so far, but only one showed up in my personal page.

but the one that did show up FOUND a factor, the other three didnt, so perhaps thats what is supposed to happen? so if you dont find a factor there is no (obvious) credit/record of the work on the personal status page?

When the program finishes trial factoring an exponent you get credit, when the program finds a factor you get a bit more credit (depending on the number of bits of the found exponent) and your factor found count goes up by one.

What you saw is normal behaviour.

could be a remnant; it was originally doing LL tests, started crashing continuously, so i deinstalled/reinstalled and kept the files that i wasnt sure about (erasing the config files though since the original remove/reinstall didnt help). when i was done i told it to do only factoring.
