Default Sequences from the 5 to 10 million range

I have been working on range from 5-10 million. I started this to answer the question whether there are any longer cycles to be found. Sequences below a smaller maximum have already been searched, but not sequences with a low minimum and a maximum of 60 digits or 80 digits.

I ran up to 10 million up to 60 digits and didn't find any. I decided to get this data into the db, but it is slow. Up to 6.4 million exist though some up to only 60 digits. I am now extending the db by sequences from 6.4-10 million with 80 digits, but with the 3000 limit, this will take over a year.

I thought I would share the following batch file - it waits if the 3000 limit has been hit (its for windows). fc compares files and sets the errorlevel if they differ. Requires grep for windows to look for the 'ourly limit' message when you can't add more. It tries every 5 minutes using sleep 300.

:check
wget "http://factorization.ath.cx/res.php" -O check.out
grep -il "hourly limit" check.out > check.error
fc check.error test.error > nul
if errorlevel 1 goto submit
sleep 300
goto check
:submit
aliqueit -s 0 %1
move alq_%1.elf done

If anyone else has interest in this, I think searching over 10 million up to 60 digits has the most chance of success, but finding the list of sequences to check is difficult. I do have the list of the ~96000 open sequences below 10 million if anyone has interest in taking anything in taking some to 80 digits. They won't be in the database, but below 60 digits is fast and 60-80 is all new.

I can take a few hundred/thousand. I can also add my findings to FDB and/or report back to you.

My sequence checkin has reached 7 million taken to 80 digits. I was originally going to do 60 digits but it looks like I can do up to 80 without slowing down my rate of adding numbers to the DB.

I have now just started the 7xxxxxx numbers. There are between 12 and 13 thousand.

Have you just added them? I've noticed a lot of composites around 80 digits have appeared in factordb over the last few days.

Hey,

I'm a newbie with an older laptop (dual core 2, but 4 gig of memory, runs 2 16e nfsnet jobs fine, Debian Sketch 64bit). I know my account is old, but that's because I ran GIMPS a long time ago (think 7 digit exponents).

I'm wondering how I would go about finding numbers with a last term (is that the right term?) small enough to make progress on my machine, and reserving them, considering that this thread has been inactive so long?

Thanks much.

Welcome!

My Core 2 Quad desktop (x64 Kubuntu 12.04) is about six or seven years old, and it runs the main project sequences just fine. It has 8 GB of RAM, but the workers rarely use more than 2 GB. Depending on how much other stuff you plan on running on your laptop while running the worker, I would try one of the sequences < 1M with a smaller cofactor (< 115 digits, perhaps) and see if that works.

Thanks, will do. If I get frustrated, can always unreserve.
