that ain't divisible by 64 |

and won't work in ffa. |
| 13:37 |
asciilifeform |
unless you push it up to next multiple. |
| 13:37 |
mircea_popescu |
so the correct work spec here is then, 4160 bits ? |
| 13:37 |
asciilifeform |
( at which point you oughta use THAT as the cap, not it ) |
| 13:37 |
asciilifeform |
btw does it makes sense why i put in that req ? |

mircea_popescu |
so ffa only allocates by... 8 byte chunks ? |

mircea_popescu |
notrly. |

mircea_popescu |
and an update when the 128 computer hits the shelves ? |

mircea_popescu |
... |
| 13:38 |
mircea_popescu |

asciilifeform |
understand, it is not possible to use partial machinewords in the simplest possible (i.e. the one in ffa) arithmetic method. |

that's where you always begin. |

asciilifeform |
'ffa represents a W-bit integer as a contiguous array of N machine words of bitness B, W = N*B.' |
| 13:43 |
mircea_popescu |
go on. |
| 13:44 |
asciilifeform |
'W is constrained, such that any permissible value of W must be representable in a whole number of machine words on 8, 16, 32, 64-bit ALU.' |
| 13:44 |
mircea_popescu |
"N must be 64 because at some point i nthe past a 64 bit machine was released and we care ; N will not have to be 128 in the future because even though an 128 bit machine will probably be released in the future, we don't understand the future and consequently do not care" |

| 13:45 |
asciilifeform |
m |
| 13:45 |
mircea_popescu |
and then why can't we use 32 bit aritm on 64 bit machine ? |
| 13:45 |
asciilifeform |
just like ffa worx just fine on opteron today dialed down to 32 |
| 13:45 |

| 13:45 |
asciilifeform |
it is idiocy and i won't countenance it. |
| 13:45 |

so then we CANT use 64 bit aritm on 128 bit machine. |
| 13:45 |

| 13:46 |

you are contradicting yourself. |

if you read the code, mircea_popescu , |

but this important point has important consequences, because now we can't have my eccentric rsa keys. must be 4096, because the only alternatives ffa permits are 2048 which is too short and 8912 which is too long. |
| |

| 13:50 |
asciilifeform |
not quite |
| 13:50 |
asciilifeform |
let's work an example |
| 13:51 |
asciilifeform |
say for some peculiar purpose, an ffa run needs 192-bitness. |
| 13:51 |
mircea_popescu |
and if your key isn't 2^n, further computers will wreak havoc on deployed code by requiring non-dividing Ns. |
| 13:51 |
asciilifeform |
this becomes 3 64-bit words on opteron; 6 32-bit words on pentium; 12 16-bit words on 8086; and 24 8-bit 'words' on 6502. |
| 13:52 |
asciilifeform |
each of which computes exactly same thing, correctly. |
| 13:52 |
mircea_popescu |
and then when a 128 bit machine comes along ? |
| 13:52 |
asciilifeform |
mircea_popescu: you can use any key bitness you like ! but gotta top it out with 0s to sit it into a ffa word |
| 13:52 |
asciilifeform |
this is not end of the world |
| 13:52 |
asciilifeform |
just like your opteron is happy to add 1 + 1, even though 1 is a '1-bit' rather than 64-bit int |
| 13:52 |
asciilifeform |
think about it |
| 13:53 |
mircea_popescu |
that part is not in dispute either. |
| 13:53 |
asciilifeform |
when on 128-bit iron , which exists today, you simply gotta pad out your payload so it sits in a W multiple of 128 ( supposing you insist on squeezing every penny of horse out of the 128ness ) |
| 13:54 |
asciilifeform |
you are already forced to pad to multiple of 8 on every iron in existence today, this is no different. and nobody will reprieve you from it. |
| 13:54 |
mircea_popescu |
asciilifeform yes, and then you're going to compute 192 keys on 256 bits, and wonder why the fuck are you not using 256. |
| 13:54 |
mircea_popescu |
which is how "it's either 4096 bits long or get lost" ends up in there. |
| 13:54 |
asciilifeform |
so you find nearest multiple that is longer than your payload. |
| 13:54 |
asciilifeform |
and use that. |
| 13:54 |
mircea_popescu |
because 4096 will accomodate all computers up to 4096 bit ones. |

aaaha here . |
| 13:56 |
asciilifeform |
ftr i considered imposing a 'ffa W is power of 2 or fuckyou' |

mircea_popescu is really pissy that "gotta use trad width keys" ended up imposed on him! |
| |
↖ |
| 13:56 |
asciilifeform |
it would simplify many routines, in particular karatsuba |
| 13:56 |
asciilifeform |
but i specifically did not like that it gives 'traditional keys' |
| 13:56 |
asciilifeform |
or at least encourages them |
| 13:56 |
mircea_popescu |
yes but i see no way out. |
| 13:56 |
asciilifeform |
and so instead went with 'mult of 64' |
| 13:56 |
asciilifeform |
this is open to debate, it is an aesthetic choice |
| 13:56 |
asciilifeform |
however P progs MUST execute to same result on ALL known iron, is the idea |
| 13:57 |
asciilifeform |
can't just say 'sorry , can't do that here' |
| 13:57 |
mircea_popescu |
no, it is not, in that it would simplify routines. that's what makes it an aesthetic non-choice. |
| |
↖ |
| 13:57 |
asciilifeform |
if instead of 'mult of 64' we had 'powers of 2', we could dispense with the odd split in karatsuba |
| |
↖ |
| 13:57 |
mircea_popescu |
anyway, i shall go eat frozen pastry and fume. |
| 13:58 |
asciilifeform |
and by extension, with the temp buffers in same |
| |
↖ |
| 13:58 |
asciilifeform |
because could instead pass the splits directly |
| 13:58 |
asciilifeform |
this is also a 10% or so speedup. |
| 13:58 |
asciilifeform |
but then you can only 8,16,....,4096,... etc. W. |
| 13:59 |

asciilifeform was going for max generality, at minimal expense |
| 14:00 |
asciilifeform |
i'ma repeat that http://btcbase.org/log/2017-08-14#1697720 is a mistake -- you can still use any key width you like. just gotta 0extend up to the permitted multiple. |

| 14:02 |
asciilifeform |
http://btcbase.org/log/2017-08-14#1697693 << and importantly, current ffa works with ( see factorial demo ) any multiple of 64, that fits in your machine memory. |

Logged on 2017-08-14 17:50 mircea_popescu: but this important point has important consequences, because now we can't have my eccentric rsa keys. must be 4096, because the only alternatives ffa permits are 2048 which is too short and 8912 which is too long. |

~ 23 minutes ~ |
| 14:25 |
asciilifeform |
e.g. 6666-bit keys work fine on ffa! |
| 14:26 |
asciilifeform |
simply take a 6720-bit W. |
| 14:27 |
asciilifeform |
recall also that, since we have karatsuba, cost goes up with W logarithmically, rather than quadratically |
| 14:29 |
asciilifeform |
incidentally, there is no reason why the ~public~ exponent , on ffatronic rsa, should not also be a large prime |
| 14:29 |
asciilifeform |
( you no longer win anything by using small ones ) |
| 14:30 |
asciilifeform |
'large' means 'occupies most of W' here. |
| 14:30 |
asciilifeform |
ALL ffa ops take time that is not dependent on the hamming weight. that's what 'constant time' means. |
| 14:32 |
mircea_popescu |
asciilifeform no dude, consider the catechistic angle. "soo... why is your key 515 byts ?" "i dunno, his lordship mp said so" "why ?" "nobody knoiws, really. he just says things." "so how do you calculate it ?" "first, you set ffa to 520 bytes..." "why did he say 515 then ?" "uh... that's a good question." |
| 14:32 |
mircea_popescu |
there's no fucking way out of it. |
| 14:32 |
asciilifeform |
well theoretically fpga |
| 14:32 |
mircea_popescu |
re exponent, it's traditionally 0101 because cheaper calcs. |
| 14:32 |
asciilifeform |
but on your current iron you're stuck with cups of a certain size. |
| 14:32 |
asciilifeform |
mircea_popescu: but not cheaper for us |
| 14:32 |
mircea_popescu |
why, no penalty to use checkerpattern instead ? |
| 14:33 |
mircea_popescu |
aha. prolly should have a "dense" prime then. |
| 14:33 |
asciilifeform |
no reason to use any particular pattern, understand, ffa |

mircea_popescu |
(ie, 50% bits set) |

asciilifeform it means there's no space for choosing, as there's an obvious right thing. |

i cannot currently say which i prefer |

asciilifeform |
( or describe a logic for showing that one is always preferable to the other ) |
| 14:45 |
mircea_popescu |
me either. |
| 14:46 |
asciilifeform |
as for the other thing, right now we have a 'classical' karatsuba that permits odd splits |
| 14:46 |
mircea_popescu |
or at least show some logic whatsoever. "it's sometimes better", anything. |
| 14:46 |
asciilifeform |
this means you can have, e.g., 192b, 384b, etc ffa |

mircea_popescu |
asciilifeform there's nothing wrong with HAVING it. and people can use it. BUT for rsa we should use the even one. |

asciilifeform no. different work to PUT satellite in orbit, and to send it an old bit of spanish grapeshot |

mircea_popescu |
hardly. 70-80 grams will do it. |
| 14:59 |

also depends, do you want to machinegun 1 sat, or... whole orbit |

homing rocket. |
| 15:01 |

this in practice is harder than simple sat launch ( the latter is not trying to fly to a specific point in space ) |
| 15:01 |
mircea_popescu |
2 stage, a 1-200kg booster thing to get it in gross range and a 2-3kg thing to power the last 100 grame spiked ball to the actual satellite |
| 15:02 |
mircea_popescu |
the cost per ton of this (materials, excluding labour and knowledge) is under 100 bux. |

mircea_popescu |
ie, less than car. |

tea was served in cups on trays. it's ok for tea to come in teabags, what. the trays also included alarm clocks set for whatever minutes a 10-bux-an-hour pinoy randomly put on the mass produced "fair trade" crappy teabags. 6 or 7 or 3 or whatever. |

"I believe Mircea Popescu has gravely miscalculated. Either he has been coloring his own BTC within the danger period (i.e. being careful of the lineage of the BTC obtained in recent times), else his BTC is also susceptible to being stolen. Otherwise, he would need vast mining resources to maintain his own fork or he would need to penalize/bribe miners to not steal his BTC where it is so encumbered. He can |
| 17:39 |
shinohai |
penalize by selling the fork and buying another honest one, but he will need sufficient mining resources and other significant BTC holders to enjoin him in this fight. Rather I think most astute BTC holders will realize this is the end of the paradigm and liquidate.' |

Logged on 2017-08-14 17:57 asciilifeform: if instead of 'mult of 64' we had 'powers of 2', we could dispense with the odd split in karatsuba |
| 22:01 |
asciilifeform |
however, the expected speedup did NOT materialize !! |
| 22:02 |
asciilifeform |
despite 50% reduction in temp space used by karatsuba mult and square |
| 22:02 |
asciilifeform |
how this can be -- remains a puzzler. |
| 22:03 |
mod6 |
so you didn't get the 10%? |
| 22:04 |
asciilifeform |
nope |
| 22:04 |
asciilifeform |
~no measurable speedup |
| 22:04 |
asciilifeform |
which is surreal. |
| 22:04 |
mod6 |
hmm |
| 22:04 |
asciilifeform |
i suspect that the reason is that the op fit in cache ANYWAY even prior |
| 22:05 |
asciilifeform |
so reducing temp space, does 0. |
| 22:05 |
asciilifeform |
this kind of optimization could be interesting if we were dealing in MB+ ffaism |
| 22:06 |
asciilifeform |
but apparently does 0 for us in the expected application. |
| 22:07 |
asciilifeform |
also imho the item above is LESS readable than the original. |
| 22:07 |
asciilifeform |
so it turns out that imposing 'powers of 2' is NOT a win. |
| 22:07 |
asciilifeform |
at least not from a mechanical pov. |

| 22:09 |

as it stands, at the moment, sounds like a mechanical push. with the ability to set the length to some power of two. i'd say it's a bit harder to follow, code-wise, with the recursive calls perhaps. |
| 22:10 |
mod6 |
but i've only scanned it once. so perhaps I shouldnt comment too much on that. |

and to simplify reading. |

asciilifeform |
( no moar foo.Z , now just foo ) |
| 22:12 |
mod6 |
ah, gotcha |
| 22:13 |
asciilifeform |
mod6: idea with this item, is that L is a power of 2 always. in 'classical' one, L can be anything (e.g. a 192-bit ffa ends up 3*64 on my box, i.e. L=3 ) |
| 22:14 |
asciilifeform |
but as it happens, my hypothesis re 'this will speed up mult' is wholly false; and the one where 'it will simplify program from reader pov' also, somewhat paradoxically, false. |
| 22:15 |
mod6 |
this might be extra-strength dumb, but... in your new power of 2 version, do you need to inline the Mul & Square of karatsuba? |
| 22:15 |
asciilifeform |
'this' being, if it wasn't obvious, the powerof2 constraint thing. |
| 22:15 |
asciilifeform |
mod6: you can't inline a recursive invocation, wtf |

| 22:17 |
asciilifeform |
^ for readers who wondered why karatsuba is the 1 routine in ffa ~not~ inlined... think. |
| 22:20 |
mod6 |
yeah, ok, so the compiler can't determine the max depth to unroll when recursive |
| 22:20 |
asciilifeform |
gnat ain't supposed to unroll. at all. |
| 22:21 |
asciilifeform |
( in so far as i can tell, it indeed respects the standard, and preserves control flow as written ) |
| 22:22 |
asciilifeform |
mod6: you can't inline a recursive call because this'd be logically equiv. to making the program infinitely long |
| 22:22 |
asciilifeform |
i thought this was clear... |
| 22:22 |
mod6 |
that's what i was trying to get at. i suppose the compiler would just reject your request to inline then, or perhaps thats ctronic thinking. |
| 22:23 |
asciilifeform |
it will |
| 22:24 |
asciilifeform |
( and it ain't an instance of 'compiler too smart for own good', either, but perfectly legitimate refusal to try to fill up the universe with your mistake ) |
| 22:25 |
asciilifeform |
the inline thing may seem like premature optimization, but function calls in ada are quite expensive, because bounds checking. so it makes MASSIVE difference. |
| 22:26 |
asciilifeform |
hence why everything that oughta be inlined, i empirically determined, and already is. |
