apgsearch v3.1

[JohanB]

Would it be possible to have precompiled executables for Win64 (and possibly other platforms).
Right now I have to pre-install gcc and jump through several hoops even though the OS is basically the same every time.
Esp the requirement to install Cygwin is something that's holding me back from doing this.

I just gave it a try, using Stephan Lavavej's MinGW distro. The build fails with the following error:

I'll see if I can fix this, but I've never really used MinGW before. Consider it a data point for now. (And here's another one: neither vanilla MinGW nor MinGW-64 seem to work, otherwise; the compilers don't recognize the new SSE registers, xmm8 to xmm15 (usually a sign of a 32-bit compiler).)

[Scorbie]

@applebottom interesting! I only used TDM-GCC for 64bit compilations. Your compiler seems to have a lot of unix tools. Is the compiler being maintained and what are the could things aof that one, if you may?
Also, I remember succeeding in compiling without catagoluebsupport...

Edit: @applebottom did you specify -m64 for compiling it to 64 bit exe just in case? (Regarding vanilla mingw not working)

Yes, it's maintained; the last version came out a little more than a month ago. Mind, I never used it before -- I only chose it because it's used to build cmix on windows platforms.

Some web-searching suggests that the above issue is due to the linker not pulling in a required library (libws2_32.a). This does exist (in MinGW\x86_64-w64-mingw32\lib), and appears to contain the unresolved symbols, but I've not been successful in getting the linker to use it.

@Apple Bottom: I remember seeing those messages before... Sorry to say that I failed to solve that problem. I am very curious why this source is not cross-platform the problematic happyhttp seems to be cross-platform (with all those Win32...whadoyoucall thst, derivatives? Inside the code)

Preprocessor directives/conditionals. And I do agree, it is ironic; my gut feeling is that there's an easy fix right around some corner, but I lack the experience to know where to look.

Edit: @applebottom regarding vanilla mingw, how about specifying -m64 just in case?

Haven't tried yet, will do so later tonight.

EDIT: Just did; here's the result:

Code: Select all

g++ -c -Wall -O3 -march=native -m64 main.cpp -o main.o
main.cpp:1:0: sorry, unimplemented: 64-bit mode not compiled in

 ^
makefile:35: recipe for target 'main.o' failed

So, no dice.

EDIT 2: I used these instructions to set up MinGW, up to and including section 4 ("MinGW-w64"; the rest was tools I didn't need).

Compilation of apgmera succeeded; in particular, appending "-lws2_32" to the end of the linker invocation actually found and pulled in that library, so the network-related symbols resolved:

(As you can see, ANSI codes also aren't interpreted by the terminal, but that's merely a cosmetic issue.)

So it still ain't working, but we're getting somewhere.

[Scorbie]

@great to see that! I meant mingw-w64 instead of vanilla mingw but it is working already We could remove the upload functionality and send the results with Python in the next release to make it cross-platform, I think...

[muzik]

Is there any way to, uh, increase search speed?

[Sphenocorona]

Is there any way to, uh, increase search speed?

Running an instance of apgsearch on every core of your CPU, and getting more raw computing power. If there was a simple way to improve the speed of the search it would have been implemented by now. From what I've seen, apgmera already uses some pretty difficult to implement methods to speed up searching; the fact that it rewrites parts of itself for the specific rule/symmetry being searched for is bordering on insane. I wouldn't be surprised if there's some things that still slow the search down and could be sped up (like classifying objects maybe) but they'll require more brainpower to figure out a better solution.

[muzik]

So, if your computer has four cores, then you should run 4 instances of apgmera for optimal search speed?



Just made a "discovery" (I'm the fourth):

https://catagolue.appspot.com/user/muzi ... iscoveries

[calcyman]

So, if your computer has four cores, then you should run 4 instances of apgmera for optimal search speed?

Or use -p 4 in the command-line options.

[Apple Bottom]

And now for something completely different...

I've occasionally been tweaking apgmera to better suit my needs, and thought that I might well share the changes with all y'all, just in case someone else might find them useful. There's no functional changes as such – the plumbing remains untouched –, but I've messed around with the porcelain, as it were. Specifically, the changes are:

• Pressing "Q" in the console will submit the current results and the stop the client. (This is useful for when you want to free a CPU core or two for other things.)
• Pressing "S" in the console will display the current census.
• The -no 1 command line flag turns on reporting of new objects. (Not recommended for all rules.)
• The -q <#> flag controls status output: 0=normal, 1=don't report rare objects, 2=also don't report progress.
• The -t <#> flag controls how long the program should run (in seconds).
• The -h <#> flag controls how many hauls the program should run for.
• The -S <#> flag controls how often status messages get printed (every <#> soups).
• Exit code indicates why the program quit: 1=requested by user; 2=all hauls done (-h); 3=time's up (-t).
• Prepend the configured rule/symmetry to progress messages.
• Output overall search speed in addition to current speed.
• There's now script to quickly compile binaries for a given rule/symmetry, or all symmetries for a given rule.
• Internal makefile changes: dependency handling, distclean target, some tweaks for Cygwin/MinGW32.

I'll be the first to admit that this is a messy patch, held together by bubblegum and duct tape, but it works.

A note regarding the "compilerule.sh" script and the -t and -h options: these are used, along with driver scripts, to automatically cycle through different symmetries in Conway Life as well as Day & Night (I've got one CPU core dedicated to these). Here's what a sample driver script may look like:

Code: Select all

}

	if [ $? -eq 1 ]; then
		exit 1
	fi
}

Honestly, the q feature should have existed in the first place.

Is there any way to do that thing in vanilla apgmera?

Heck yeah. Moving on up in the ol' searches. (now give me an xp19 already so I can be remembered forever)


dvgrn was mentioning in some discussions in the spaceship thread that we should encourage a lot more people to use apgsearch and Catagolue. How would we go around dong this?

More importantly, how do we stop events such as the infamous Apple Bottom and I crashing Catagolue when I was away from home and left my computer searching? Because that would drive away traffic pretty badly.

That's rather strange. What command exactly did you run?

Three possible snags I can think of right now:

a) the patch applies to a clean checkout of apgmera 3.28; best untar a fresh copy to work with.
b) if you're saving this in a text editor on a Windows system, be sure to convert it to Unix line endings first so patch(1) won't get confused.
c) I've been working off this commit, as all the following ones are doc changes only. (This shouldn't make a difference, but -- famous last words.)

EDIT: line endings ARE an issue; apgmera's codebase uses DOS line endings. I probably converted it long ago and then forgot. Fixing that, here's the result you SHOULD be getting:

Why do some hauls have blue links? I know yellow is uncommitted, red is rejected and green is normal

Something else again. apgmera's currently got a problem where it crashes with a stack overflow when running on certain rules. I first noticed this on March 13 during alpha-testing, running version 3.04 on B3678/S35678 using seed m_W8v7RkVS4Gg4.

Calcyman investigated, and identified the offending soup, #947595:

He said:

That is to say, it's currently trying to process an object with a population of 1505635, namely that huge growth pattern.

It strikes me that the segfault is caused by attempting to declare the (local, therefore on the stack!) array coords with a size of over 12 megabytes. Replacing this with a std::vector<int> seems to circumvent the segfault, but the program subsequently takes forever trying to run this enormous object for thousands of generations in QuickLife.

These stack overflows have occasionally reared their head since then in various rules, including the higher symmetries of Day & Night. With some rules they're not a big deal; with others they occurs so frequently that soup-searching those rules is all but impossible.

I got bitten by this (or at least SOME stack overflow) again today after (foolishly, perhaps) deciding to poke at B368/S12578. Dave Eppstein mentions this rule in "Growth and Decay in Life-like cellular automata", saying:

B368/S12578 like HighLife supports a simple replicator, in the form of a 1 × 5 block of cells; it copies itself every 13 time steps. This replicator may be used to form oscillators of arbitrarily high periods; combinations of these oscillators can form guns for a small c/8 diagonal spaceship supported by this rule. As with HighLife, it seems likely that push-pull reactions can be used to form spaceships with arbitrarily slow speeds. However, with random initial conditions, this rule forms regions of chaotic activity interspersed with other regions of small oscillators and still lifes (Fig. 6.10), indicating a mixture of Class II and Class III behavior.

(That spaceship is glider 1297.)

The rule is extremely slow to search in apgmera, thanks to replicators and PATHOLOGICALs, and the stack overflow eventually happened after about 10 hours and 328 soups, and ~43000 objects. (Not to mention about a million lines of debug output. ) The seed used was m_f8A3KfGPE84g.

For the benefit of anyone wanting to investigate similar rules in the future, here's a pack I used to a) produce said debug output and b) submit results after 250,000 objects had been censused (that bit's entirely untested, and knowing me therefore will likely not actually work). Note that this applies on top of 3.28-ab7.

I don't know if it's the same stack overflow, but -- TL;DR, would be great to see these fixed.

Sorry for not-trying-before-asking, but does this compile with 32bit windows with a cpu that has 64bit instructions? Thanks.

You'll need a 64-bit toolchain (i.e. C compiler etc.), which may or may not require a 64-bit OS underneath.

Going out on a hoof -- if you're using Cygwin, you'll need the 64-bit version of that, which (probably) requires a 64-bit OS, and you'll also need the Cygwin environment to run the program. If you're using MinGW, you'll probably need a 64-bit OS unless you're cross-compiling, but the resulting binary should work on 32-bit Windows versions, so long as you have a 64-bit CPU.

But take all that with a BIG chunk of salt, and try for yourself. (Also, let us know the result, no matter whether it's "it worked" or "I ran into trouble"!)

Sorry for not-trying-before-asking, but does this compile with 32bit windows with a cpu that has 64bit instructions? Thanks.

You'll need a 64-bit toolchain (i.e. C compiler etc.), which may or may not require a 64-bit OS underneath.

@Apple bottom Installed msys2 which gives me mingw-w64. I'll try with that and see if it compiles, in the upcoming tuesday.

[Scorbie]

msys2 32bit on 32bit OS cannot run mingw-w64_x86-64-gcc. (Thought it was a cross-compiler, but I guess not.) I guess one can compile 64bit software on 64bit only with msys2.

@Applebottom speaking of msys2, I think it is pretty nice for these kind of tasks. It works similarly to cygwin, has the pacman from Arch Linux, and seems to build native windows software without POSIX emulation or dll dependencies.

Could you follow these steps to see if it works?

1. Go to MSYS2 installer and follow instructions. You can access MSYS2 shell, mingw-w64 32bit and 64bit (target arch) shell from the start menu.
1-1. The update seems to be slightly broken for now. After you update, the symlinks in the start menu seems to be broken. Change them to:
msys2: C:\msys32\msys2_shell.cmd
mingw-w64 32bit: C:\msys32\msys2_shell.cmd -mingw32
mingw-w64 64bit: C:\msys32\msys2_shell.cmd -mingw64
2. launch msys2 shell and type pacman -S python2 make mingw-w64-x86_64-gcc.
3. get the apgmera source. In recompile.sh, change "python" to "python2". (Seems msys2, as Arch, uses python3 as the default python package.)
4. launch mingw-64 64bit shell and run recompile.sh and install any dependencies with pacman if necessary? I dunno...

This seems to be the easiest way to make it work, if the dependency is resolvable by pacman.

About the three shells, if I got it correctly:
msys2: compiles msys2 packages(?) or programs not for distribution. Depends on msys2.dll or something like that. Uses a posix emulation layer. I'm pretty sure cygwin is better that this only.
mingw-w64: compiles native 64bit binaries without dll dependency. Needs to install package mingw-w64-x86_64-gcc to work.
mingw-w32: compiles native 32bit binaries. mingw-w64-i686-gcc needed.

I tried, but as far as I can tell msys2 does not package g++. Perhaps it's just a matter of finding the right package, but I've not managed; it's not in the mingw-w64-x86_64-toolchain bundle.

You sure? You might have opened the wrong shell. You should launch mingw-w64 shell, not msys2 shell.

(I tried to make it boldface, but apparently there seems to be a typo in my previous post.

Derp. Let me try that again.
