Question "How many stages"?

[Matthias C. Noc]

Hello,

I'm new and my client just started to crunch. The window is showing from time to time the info that stage 1 is XX % complete. Just to get a better understanding of the process, how many stages are there for "p-1 factoring"?

Thanks,

There are 2 stages of what is called P1 factoring. If the client doesn't find a factor it will proceed to the Lucas-Lehmer test.

Welcome to GIMPS . Good hunting

Can factors be found at the end of both stages or at the end of stage 2 only?

Okay, I see. Thank you. And after the LL-Test?
How can I see how much progress the calculation has done in general; compared to the total necessary for this one?

Back at seti@home we had a kind of status-bar, is there something like this for this programm too? Maybe a 3rd party tool?

Thanks,

Matthias

If you are running the windows client it will tell you if you hold the mouse over the taskbar icon. It will also tell you in the window.

If you are running Linux there is a utility called gkrellmGIMPS, that will monitor the client and display the status.

If you are using Linux, there is a small Perl utility that you can use to determine how many iterations the calculation has progressed.

Look for the save files p.... and q.... in your mprime directory, then run the following Perl script with the p.... filename as the argument:

#!/usr/bin/perl
 
$file = shift || die;
 
open (FILE,"<$file") || die;
 
read(FILE,$temp,6);
 
($type, $counter) = unpack("sL",$temp);
 
print "$type $counter\n";
 
close (FILE);

Factors can be found in either stage 1 or stage 2... or neither (no factor found).
