Re: A Broader Audience for Cellular Automata

This page probably has what you want -- I only know BOINC from the user end, but this page explains how to package your project so BOINC users can run it with good control over how it runs on their machines.

Re: A Broader Audience for Cellular Automata

A minor point: we do have lots of natural glider guns in Catagolue, just none in C1. We have many interesting symmetric patterns in the higher symmetries that do not occur in C1, partly because the symmetric domains are larger, up to 32x32, and can easily produce larger objects. Based on the variou...

Re: A Broader Audience for Cellular Automata

Reviving an old suggestion -- I would like to see apgsearch available through BOINC, which is where many folks go when they want to put their spare computer cycles to good use. I contributed to BOINC after TOLLCASS ended and before I found apgsearch. Conway's Life is at least as much of a "good use"...

Re: apgsearch v4.0

Today I've been running v4.92 under cygwin vs. v4.95 in a Windows cmd window on our AVX1 machine, both at low priority. v4.92 10101101 soups/haul v4.95 10101106 soups/haul Using command line options, v4.95 is running 1 to 3% faster, but it doesn't stop on "q".

Re: apgsearch v4.0

Should I switch to v4? V4 is faster now than it was a year ago, and it now runs b3s23 faster on all of my machines. I recommend making a copy of your install, upgrading the copy to V4, and running one instance of each version side by side. If V4 is still slower on your system, Calcyman will want to...

Re: apgsearch v4.0

So it looks like v4.82-ll2.1.5 is at most 2% slower than v4.72-ll2.0.27 -- the 5700003 has only lagged by 10 minutes against the others over a period of 9 hours. You may have included an interval when the machine wasn't running. It looks to me like the 5700003 run is losing between 2.5 and 3 minute...

Re: apgsearch v4.0

b3s23/C1 runs more slowly in v4.82-ll2.1.5 than in v4.72-ll2.0.27 under cygwin on our AVX1 machine. You can compare my hauls with these total numbeers of soups:

5700001 v4.72-ll2.0.27
5700002 v4.72-ll2.0.27
5700003 v4.82-ll2.1.5

Re: 1% Density Soups

In a variation of your notation, with capital letters for cells in one copy of the domain and lower-case letters for cells in six surrounding copies of it, a doubly-twisted toroidal domain can look like this: e3 e4 e5 h1 h2 h3 c1 f3 A1 A2 A3 A4 A5 d1 g3 B1 B2 B3 B4 B5 e1 h3 C1 C2 C3 C4 C5 f1 a5 D1 D...

Re: 1% Density Soups

I think that rotating the fundamental parallelogram is not equivalent to rotating the grid to eliminate skew in one direction. Golly's methods for twisting grids on a torus cause a *WSS along one axis to vary its path across the rectangle, but a *WSS along the other axis retraces its path. We are tr...

Re: 1% Density Soups

Sure, an untwisted torus with any ratio between dimensions without a common factor will give the result you describe. Yes, the path will cover the domain, but if the ratio of sides is near a ratio of small numbers, a glider's path will drift across the domain in small steps, and a large target will...

Re: 1% Density Soups

It's also possible, although I don't know how easy it is in Golly, to twist the torus, so that when a glider exits from one side of the field, it doesn't appear directly opposite on the other side. Twisting is not necessary. If the sides of the toroidal domain are two consecutive fibonacci numbers,...

Re: apgsearch v4.0

4.44's speed was much more volatile I also have the impression that v4.44's speed per interval is more volatile in b3s23/C1 . I didn't report it because I haven't looked at enough logs to resolve two issues: 1. This might be an artifact of the different averaging scheme -- v3.28 waits for 10000 sou...

These are all running under cygwin with reduced priority.

WSL is only for Windows 10.

Re: apgsearch v4.0

1. apgluxe runs at least a few percent faster than apgmera. Does this hold across all three architectures (SSE2/AVX1/AVX2)? Was this with v4.43? Yes, this was for all three architectures with v4.4 . I have started a new test against v4.44 showing more substantial gains in speed -- see below. Have y...
