Calling Mini-Pi a "state of the art" is probably being a little too generous.

I quite literally slapped that thing together over a weekend with no effort. No real optimizations. Even GMP Pi is faster.

The reason why Mini-Pi gets any attention is probably because it's a single self-contained file.

I know y cruncher and I repeat That this Apps are for mobile phones and With the app could calculate more decimals than 20000, this apks are for curiosity and for up temps of my Hands In winter,by the other hand the Apps run correctly and its fast not more fast than Apps use agm.

HERE a video of Mersenne app in Android and comparison With apk Lucas lehmer in Google play.

[QUOTE=Batalov;504980]Now if you compute 100,000 digits of Pi today, it will not even get you laid.[/QUOTE]

Did that ever get anyone laid, at any point in human history?

Empirically [I like using that word], that sort of thing has the precisely opposite effect.

Or, uh... so I'm told.

Sheesh, instead of steadfastly dodging it, just answer the question: "which algorithm of LL testing do you use ?" Or, what method is used to do the squaring? Here, I'll try to make it easy, multiple choice:

a) grammar school conventional long multiplication (using what "digit size") Twice the exponent, four times as many partial products to compute and sum, for each of twice as many iterations.

b) Karatsuba divide and conquer. Twice the exponent, [B]THREE[/B] times as many partial products, plus some additional overhead. (applied recursively, or not?)

c) Toom-Cook (for extra credit, which?)

d) modular multiplication (using which relative primes?)

e) fft (in which base?)

f) a mix depending on operand or exponent size (which, and at what breakpoints)

g) can't say, prepublication (what journal, and publication expected about when?)

h) super secret new faster than linear, proprietary, classified, NSA and KGB and Spain's National Intelligence Agency are after thorken for releasing it in executable form:shark:

i) Other (specify)

What programming language did you use?
Or put up some source code so we can look for ourselves.

(Are you by any chance acquainted with Billy Rubin?)

Does anyone reading this have an Android dev-board with which to try an Mlucas build with? It would be best if it were one with an Arm CPU supporting the 128-bit SIMD instructions (a.k.a. Arm v8+), but even failing that one could try a generic C-code build using a scalar-doubles-based FFT.

(Of course the OP is welcome to try same, but at present OP seems to be busy fending off rude questions about his bigint multiply algorithm. ;)

They were just saying that's one possible way some program without source given could be both fast and accurate to what's already known. As shown a interpretted script can run faster. Also I got that lucas Lehmer app you talked about, when it takes 27-28 seconds for 12711 then yes many programs could run faster. that's why coders use asymptotics.

[QUOTE=ewmayer;505054]What exponents are those timings for, and on what compute hardware?[/QUOTE]

same exponents as OP, on the only working hardware I have at last check an android phone. I think it has a snapdragon processor, and PARIdroid was 2.11.0.1.5 edit2: seems my PARIdroid thinks they aren't prime though...

Ok, in fairness to thorken, in post one, he says he found the application on a phone, and makes no claims to having written it.

“Tenia” translates into “had”.
“Mersenne cousin numbers”, please replace cousin with prime.

[QUOTE=ewmayer;505069]So your simple Pari script running on Android is nearly 4x faster than [url=https://mersenneforum.org/showpost.php?p=504895&postcount=38]GP2's GMP-based LL tester[/url] running on an AWS Skylake core?[/QUOTE]

I didn't write it. It's adapted from [URL="http://rosettacode.org/wiki/Lucas-Lehmer_test#GMP"]RosettaCode[/URL], mostly by ripping out the preliminary TF stuff and making it print out a residue.

GMP isn't that complicated and I could have written a simple LL test myself, however this code incorporates an optimization for the modulo that probably wouldn't have occurred to me.

You are wrong, I am sure it was about either [URL="https://en.wikipedia.org/wiki/Taenia_coli"]this[/URL] or better [URL="https://en.wikipedia.org/wiki/Taenia_(cestode)"]this[/URL]...
