Default Fast Breeding (guru management)

These two Fibonacci numbers were suggested by Batalov a few months ago, they can still be sieved:

Fib(1405) C235
x^4+3x^2+1
x-L281
SNFS difficulty = 234.6

Fib(1415) C236
x^4+3x^2+1
x-L283
SNFS difficulty = 236.2

Both have survived enough ECM (17769 curves @110M by B.Kelly).

Those are both on my list of potential candidates. I just skipped them for now since I haven't looked at the parameters for a quartic in a while. As quartics, I think they are more appropriate for 15e.

Looking at the list of remaining Fib/Luc numbers in range of 15e, after the current batch we have 1 quintic (L1397), 16 quartics (F1405, F1415, and 14 Lucas numbers from L2645A to L2855A/B), and 7 GNFS (F2145, F2163, F1585, L2037, L1502, L1583, and L1541). I'll need to look up those quartic parameters again soon.

(lots of blocks pending and none completed)

mean I've got the polynomial file somehow wrong? Could someone competent have a look at it?

I see a lot of blocks completed but I don't see on the server where the relations are saved. C170_5748_1537 folder is empty.

Same thing with lasieved.

Top entry sitting at 201M completed and 32M est. pending for nearly a day.
Number of pending dropped from over 500 to 300 with no change in the relations count.

The update script probably went belly-up in a persistent way again. This occurs once in a while.

The statistics issue appears to have been resolved. I have added a few more Q to some of the 14e numbers, but GW_7_288 is ready for linear algebra now.

Default Feeding the Beast (queue management)

The 14e queue is currently low, so I've queued a relatively easy (SNFS 233) near-repdigit number, though not started it yet.

Rich Dickerson recently suggested the 7103^61-1 and 7331^61-1 OP numbers, SNFS difficulty 235, on which at least 10K curves at B1=43e6 were performed. I'm hereby reserving both. It's been a while since we did OP numbers

We still have several GCW numbers suitable for 14e, don't we ?

I'm not anticipating queuing anything for a while: my polynomial-selection resources are all devoted to 114!+1 and it will be a week or so before I have a polynomial. It looks as if yoyo@home has thoroughly ECMed several GCW numbers, I'll leave the choice and enqueuing for those up to xilman.

I have asked yoyo@home to do substantial ECM on the three XYYXF C17x cofactors with highest SNFS:GNFS difficulty ratio, and will feed those (at least one to 14e, probably two, possibly three) once the ECM is done and I've found a polynomial.

I've put the two mentioned OPN numbers on; it would be good if xilman or someone could put up some more GCW, otherwise the queue will drain quite fast.

I had a look at GC_11_239, but it's too big for 14e.
