The haul of 10000 soups is uploaded, but the haul of 100000000 soups is not.

Not number of soups, but rather file-size: there's a 1-megabyte limit on all uploaded hauls.

There's a haul size limit of 1 MiB. Day & Night generates very large hauls; the practical limit for C1 is ~8,000,000 soups, and much less for the higher symmetries.

This is also why, when investigating rules you've not investigated before, it's generally a good idea to do test runs to gauge the size of the generated hauls (and the search speed, obviously). When choosing the final haul size I generally aim for a time of about 2 hours between hauls, subject of course to the size additional constraints.

Speaking of which, there's also some minimums imposed: hauls that reach neither 10k soups nor 250k objects are also rejected. Combined with the 1 MiB size limit, this renders some rules unsearchable on Catagolue.

My processor is Intel Core i7-6700, it has 4 cores and 8 threads.
How many threads should I parallelize Apgmera on, "-p 4" or "-p 8"?

Eight will eke out some extra performance -- not quite double, but enough to be worth it. On my Core i7-3770K, I get ~1,450 soups/sec*instance if running eight instances (11,600 soups/sec total), and ~2,200 soups/sec*instance if running four (8,800 soups/sec total).

Interesting things seem to be afoot. A new symmetry, SS, showed up, with hauls being generated by a tool called "hs", and sample soups looking like this:
These seem to be based on firing slow glider salvos (hence also "SS") at distant objects and seeing what evolves. Can't wait to hear more!

Here's another one, not mine obviously:

I'm pretty sure somebody just modified an existing salvo-search script to upload found objects to Catagolue (a pretty economical move considering it's already a well-fleshed-out way to store data about SL occurences) and the results are showing up in the tabulations.

That somebody being Calcyman himself, mind -- and there was some server-side support needed, too, e.g. for sample soup (re)construction.

Hope we'll get a code drop for the new tool some time!

BTW, I noticed a discrepancy in the figures for the B3/S23/SS stats. The census currently says:

The following census was compiled from 926 committed hauls containing 456 028 192 614 objects generated from 3 732 136 786 soups.

However, the textcensus contains fewer objects:

Apologies for triple-posting, but I noticed that Catagolue's reached half a million submitted hauls now. This one (submitted by benetnasch85 and verified by goldtiger997) is the 500,000th one, if I'm not mistaken. Congratulations!

Professor and cloverleaf interchange still aren't named on Catagolue yet.

Hear ye, hear ye! Apple Bottom has contributed 10 trillion objects to Catagolue!

Aww shucks, sugarcube. 'taint nothin'.

And yet those two still lifes still aren't named...

What if we made a version of apgsearch that searches big sparse life soups (something like 1000x1000)? It sounds really dumb but it's merely a suggestion.

Seems interesting.

How sparse?

fluffykitty wrote:How sparse?

Sparse enough. Beyond a certain limit, lowering the probability of a live cell doesn't alter the distribution of objects; in fact, it just has more blank space in between them.

Are you referring to the z-order of the bars in the chart? That's beyond my jurisdiction; you should be complaining to the creators of Highcharts instead.

Okay. On an unrelated note, we only got about 45B objects yesterday. When will the new apgsearch release bring us back to 1T/day?

The 1T/day was when I was running apgmera on roughly 150 or 200 cores in total. The easiest way to get back up to that is for me to resume deploying on many cores -- there isn't really any possibility of attaining a significant speedup just using CPUs.

How did you get 200 cores to run apgmera?

How do I check the lifetime contribution of someone to B3S23C1?

fluffykitty wrote:How did you get 200 cores to run apgmera?

By having ssh access to about 60 machines of varying sizes (mostly quad-core machines).
