A computation worthy of the name - Page 5

A51-61: 22295685 relations in 31.2 MSec (k8/2000)
R51-61: 21420892 relations in 29.9 MSec (k8/2000)

I'm attempting to upload now.

I have a few other commitments, so won't make another reservation immediately. Should be back in a few days.

... and ran into upload problems before the edit window even expired :(
I suspect this will take some PMing back and forth.

I don't know why, but it strikes me as amusing to use a unit of "seasons" to measure time for jobs this size

Where I live this time unit is not even constant, winter being much longer than spring or fall, and eons compared to summer (at least psychologically).

R68-69M, 2.1M rels, 2.0Ms on k10/3000; again with only ~3K internally redundant relns in it. The extended graph is: second verse same as the first (not shown). Importantly, there was no yield dip anywhere (not even a delayed one).

The 16e siever looks good; I will now retire to finish a gnfs-174 (ETA 12 days for a 12.2M matrix).

I don't get this. Do you fly around at 0.4c during the fall, and remain in one place for the winter?

Where I live there isn't a season called "fall"...

(I apologise for this one)

Astronomically speaking, seasons are (almost) equally long, but the duration of meteorological seasons can extremely vary. For example, here in Austria, in 1996 summer fell on a Wednesday 1st of may), and autumn lasted from 2nd of may until November. (in august of that year I heard a joke in the radio: "France wants to cancel summertime. We are even more advanced - we have canceled summer.")
In contrary, in 2003 summer lasted from mid of April until the end of September (including extreme heat-waves from June to august), autumn was only 3 weeks in October, and winter started with heavy snowfall in the night from 23rd to 24th of October.

so you don't need to go at relativistic speed to get seasons of varying duration.

That was quite deliberate; seasons are somewhere between two and five months long, I don't know how big the matrix for 2-941 will be, but I suspect it'll take between two and five months to run.

Sometimes, but the gas bill is starting to kill me. More often, I spend the winter in a large gravitational potential

Good thing we are coming up on winter... this could be a big matrix! Shouldn't get too cold in your study, at least.
