Setting up aliqueit

I would suggest asking your question in the Aliquot Sequences forum: http://www.mersenneforum.org/forumdisplay.php?f=90

can anyone else help ?

OK, first question: what is your environment like (what CPU and OS are you running)?

If you'd like to look over my AliWin2 page, it might offer some direction. It is 32-bit and directed toward WinXP and running Aliqueit via AliWin, but it might get you started. You can set up the factoring programs without using AliWin. You can also look at the thread on AliWin if you'd rather, before going to the page.

it's in the quoted materials : 64-bit windows 7 SP1 on a machine with a Pentium D CPU and 3.19 of available ram.

Sorry, I totally missed that when I was reading the message earlier.

Let's see what we can do....

• Create a folder somewhere. I have mine set up this way: "c:\aliquot\auto\"
• Go here and download Aliqueit 1.12
• Put Aliqueit and either miseve.exe or yafu.exe (or both) in the "auto" folder
• Put a copy of GMP-ECM.exe in the folder, too.
• Edit the aliqueuit.ini file to point to the exes:

  //Executables
  //
  //Name (and path, if needed) of your gmp-ecm executable.
  ecm_cmd = ecm
  
  //Name (and path, if needed) of your yafu executable.
  yafu_cmd = yafu
  
  //Name (and path, if needed) of your msieve executable.
  msieve_cmd = msieve

• Set a cut-off for the switchover to msieve/yafu:

  //Use GNFS for composites >= this many digits.
  gnfs_cutoff = 99

Now that you have everything installed, let's test things out. Try this and see what you get:

aliqueit 840

In a few minutes (or more, depending on speed) you should get the complete sequence for 840 ending with this:

 736 .   c4 = 4600 = 2^3 * 5^2 * 23
 737 .   c4 = 6560 = 2^5 * 5 * 41
 738 .   c4 = 9316 = 2^2 * 17 * 137
 739 .   c4 = 8072 = 2^3 * 1009
 740 .   c4 = 7078 = 2 * 3539
 741 .   c4 = 3542 = 2 * 7 * 11 * 23
 742 .   c4 = 3370 = 2 * 5 * 337
 743 .   c4 = 2714 = 2 * 23 * 59
 744 .   c4 = 1606 = 2 * 11 * 73
 745 .   c4 = 1058 = 2 * 23^2
 746 .   prp3 = 601 = 601
Sequence merges with earlier sequence 601.

(The last line may be different if you have detect_merge set to false....)

I put the binaries in the folder with aliqueit to keep the paths simple, and I keep the qs/nfs cutoff kept pretty high since my dual-core can handle large composties nicely with yafu dual threaded.

Let me know if you get it working this far.

I got it working as far as the test then don't see where to put the test case unless it's a command line thing to do from run because aliqueit never seems to stay open long ( either version that came in the download).

Bingo! If you double-click the program, it just prints some help text and then exits.

What you need to do is run it from a command window (cmd window, DOS box, whatever makes more since to you).

One way you can set it up is to create a shortcut in the directory for a cmd window. I'm on my Vista machine right now, but I can double-check the procedure on my 7 machine a little later.

Open up your work folder (again, mine is c:\aliquot\auto), open the Start Menu -> All Programs -> Accessories -> Command Prompt, right-click and drag to the folder, then drop; click on "Create Shorcuts Here". Then right-click the shortcut, select Properties, and change the path under "Start In:". On Vista, it defaults to %HomeDrive%%HomePath% which opens the command window in c:\users\<MyAccount>. I would make mine c:\aliquot\auto, which results in a command window with a c:\aliquot\auto> prompt.....

I followed through with run:

C:\\aliquot\auto\aliqueit112\aliqueit_win32.exe 840

and the attached printscreen cropping is what it reads.

OK, that means it probably isn't finding the qs program. What are you using, msieve or yafu?

EDIT: scratch that, it isn't finding either ECM or the qs program.....

Open the command window, run a dir, and paste the output here....

I think I know why this happens:

your instructions ( which I followed somewhat out of order but got this far) never say to download ggnfs but your instruction do hint that it might be nice.

Actually, it's not going to try GGNFS yet. 840 never gets over 50 digits, so it will just run ECM or qs to tackle this. Re-check my post above; I edited it after I posted it.
