I quite literally slapped that thing together over a weekend with no effort. No real optimizations. Even GMP Pi is faster. The reason why MiniPi gets any attention is probably because it's a single selfcontained file.

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, THREE times as many partial products, plus some additional overhead. (applied recursively, or not?) c) ToomCook (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 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 devboard with which to try an Mlucas build with? It would be best if it were one with an Arm CPU supporting the 128bit SIMD instructions (a.k.a. Arm v8+), but even failing that one could try a generic Ccode build using a scalardoublesbased 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. ;)

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... Last fiddled with by science_man_88 on 20190105 at 21:02

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.
From his third screen shot: Code:

“Tenia” translates into “had”.
“Mersenne cousin numbers”, please replace cousin with prime. Last fiddled with by pinhodecarlos on 20190105 at 21:25

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.
