    Sure, not being around makes it kind of difficult :-)

    This is where a network aware factorer (be it P-1 or ECM) would be useful. It would:

    1) Allow you to reserve specific k,n pairs.
    2) Provide progress updates to the server. You could then install it on various machines and use the server's website to see the progress of all of your machines.
    3) When providing an update (say every 30 minutes) the server could say "Don't bother, just got a factor for it."
    4) The server would keep a record of the B1/B2 bounds (for P-1) and B1/B2/#curves for ECM. This prevents duplicate work (for P-1) and also helps determine digit-level testing for ECM. If large storage is available then P-1 save files could even be stored for future bound extension.

    And even better:-

    5) It would allow you to point the client at the server (with no specific range assigned) and be given some work to do, a la PRP client.

    However, as mentioned in the Sieving forum regarding a networked sieve client, the hard part is not having this idea. It's actually coding it, integrating it with the current site and actually finishing it to such a level that you are confident that there aren't any problems. (Even finishing it is difficult, so many projects like this start out with good intentions but then die a slow death).

    I suppose the easiest start would be using the ecm server like elevensmooth...
    pROBLEM is ecm6.0 isn't net ready if I recall and it's still not as good as prime95.

    Perhaps it would be possible to use the code from ecm-client to obtain pairs and a script or something to run prime 95 on the numbers. We could easily setup the co-ordination to have the net client do one particular k or reserve ranges for it etc...

    As in the above post all good intentions the only problem is the implementation.

    Currently it's just as easy to reserve well in advance. IF your not going to be albe to touch a machine for a year... reserve 12M-12.1M and let it rip.

    The wrapper is exactly what I was thinking. However, I've got enough on my plate at the moment and I don't want to be distracted. :-)

    P-1 found a factor in stage #2, B1=100000, B2=200000.
    67607*2^9978507+1 has a factor: 213405559922726473
    213405559922726473 | 67607*2^9978507+1


    Himmm, this is the second k/n pair that simply slipped away during the first few weeks when I was out of town... First one was found on Sep 3rd and this one on Sep 20th.

    I'll soon start the second pass (B1=200000, B2=2000000 stuff), for which I'll have to recreate the worktodo ini with the latest results file. Hope the same doesn't happen this round, as it becomes somewhat frustrating to see no progress despite a factor found.

    So Nuri have you decide if your going to increase B1 or just B2 for a secondpass?

    Yeah, I decided to skip 200k, 2m and go directly to 300k, 3m.

    I think that will be sufficient... but if not, I'll increase only B2 from there on.

    Fifth contribution from the sieve... which is really cool, as it gets harder and harder to add up even a single factor at the current P-1 levels

    Looking good Nuri, congrats!!! Do you think you will bring the level below 1000 before we find a prime? I believe you will.

    Thx..

    My guess is that it will take at least a year more to reach there... not to mention, of course, that my hopes are for an earlier meltdown.

    How is this going Nuri, it looks like your close to the end of B1=300K with B2=20xB1. It also looks like you decided to increase B1 to 400K?

    Not suggesting you do it but...

    7509426046902223253 | 67607*2^9851931+1
    via p+1
    7509426046902223254 = 2 x 3 ^ 2 x 829 x 8539 x 195967 x 300739

    I was out for a few days...

    In fact, I'm using 300k for roughly half and 400k for the other half.

    WOW Nuri excellent success as of late.

    5 to go perhaps one more from the sieve???

    Noticed you had to extend B1.

    On the second question...

    I'll probably spend some time on P-1 or old friend, sieving..

    On the other hand, there's still eight more challanges between 1m and 9m on 67607...

    Haha... good point

    May be, I should wait and submit last three together, hehe...

    Kidding aside, no problem at all.

    BTW, I decided to finish up remaining tests with lower bounds once I (hopefully) reach 999. Tests left;

    B1= 300000, B2= 6m, 40 tests
    B1= 400000, B2= 8m, 15 tests
    B1= done to 400000, B2= 6400000, 32 tests
    B1= done to 400000, B2= 8000000, 332 tests

    Overall ETA: End of August.
