Factoring database

[Andi47]

I have just noticed that when I set a worker on a composite and it finds a factor, the cofactor does not "inherit" the work already done from the original number. (e.g. the TF buttons will be available for the cofactor, although the original number has already been TFed.)


P.S.:

Normally I proceed as followed: TF to 1e7, ECM low limits, ECM medium and/or high limits, and then sieving (for numbers <~c90) or ECM very high limits (I have only clicked this button one time, i.e. for one composite.)

When I tried yesterday, I proceeded nearly straight forward to very high ECM on a c119 I had posted, because I had already done TF and a bit more than "ECM high limits" does on my own PC.

These two workers are offline - so why are there jobs assigned to them?

P.S.: Yesterday I noticed, that when a "ECM very high limits" job is running and I click the "ECM very high limits" button for another composite, the previous ECM very high limits job seems to be completely killed. I would suggest to either share the available workers to these low priority jobs, or put additional low priority jobs into a queue.

Thats a little glitch, when sieving takes too long the worker does not react and is shown as "offline", maybe i'll fix this later.

The work queue for low priority jobs is now online, hope it works as expected!

the very high ECM option will only be available, if some (has to be defined) low, medium, high ECM efforts are done!

Is also in code now. The limit is just "any ecm work done"

Hope you like it

As you don't have answered to it: Have you seen the issue which I posted one posting above you?

When a factor is found (TF, ECM, etc.), the composite cofactors do not "inherit" the work done on the original number - i.e. the TF buttons are again available, even if the original number has been TFed to 1e7, and the ECM count of the cofactors is zero, even if some ECM has been done on the original number.

Oh sure, read it, but forgot to answer it.
I'll try to fix this soon, this one is a little more complex.

Just curious. How many numbers / factors are in the DB?

Lots. Atm About 28M numbers / 41M factors > 2000.

Hi Syd,
do you feed the factors which are currently found by the various projects into your database? From which projects?

Hi yoyo,

I only import them manually from time to time, its quite hard to extract them automatically from the various projects.
Do you automatically add them to your "y_factors_ecm.php"-page? If so you could do me a favor and add a line like this one, please?

file("http://factorization.ath.cx/search.php?query=".urlencode("555^x-x^555")."&reportfac=1234567");

that would save me a lot of work!

Yes, all numbers are added automatically there. Currently the ecm boinc system is a bit in a beta stage for some b1 ranges, therefore some wrong numbers are added automatically and I remove them by hand.

Can you accept my ICQ request, than we can discuss it more detailed.

Workers 13 through 16 seem to be offline.

Markus, could you add a time zone setting? The "Reported" times are always in GMT+1. (Of course, tomorrow will be really confusing, because that's when BST starts.)
