bvt: asciilifeform: a better attempt at this algorithm can involve using comba at the lower level.
asciilifeform: it allows reader to see what is bought by adding the moving parts.
asciilifeform: sorta why, when i first started preparing the thing for publication, wound it back to the simplest known ('egyptian') variant, and walked from there.
asciilifeform: bvt: there's a long list of things that asciilifeform considered and (for time being) rejected from ffa, on acct of costing substantial complexity for very small saving of cpu cost. e.g. unrolled comba.
asciilifeform: there was another fella (since wandered off) who posted last yr an attempt at de-recursivizing karatsuba ( it's definitely in the logs, can't find it just yet tho )
mircea_popescu: there's that old joke re "i read good books twice but bad books i don't read at all" which very much applies : if only one knew before looking whether an algo is fast or slow!
bvt: no, i mean that particular paper. i initially wanted to implement a fft-like multiplication algorithm, but got interested in this karatsuba/toom when reading the paper.
bvt: nope, but there were a few mentions of other algorithms in the logs, so i decided to have a look. don't remember how i arrived at this particular one
asciilifeform: i assumed bvt knew of a use, given that he dug out the ru materials on subj
asciilifeform: bvt: i don't, which is why never bothered with fft
bvt: re fft: i would wait until a use-case appears, to at least understand what are the requirements. do you have something in mind?
bvt: yes, actually in this karatsuba/toom algo one can embed comba's trick, but the code would become even gnarlier
bvt: also, the linked pdf contains one FFT-like algorithm i considered to implement (using walsh transform for convolution instead of fft). but it'd be even more complex
asciilifeform: bvt: you have more than twice the # of cache evictions
asciilifeform: mircea_popescu: i'm not surprised, considering that bounds check overhead (in ada with all safeties switched on) magnifies the 'losing' of a losing (for particular width) algo
bvt: yes, and it's also true for memory accesses. however the number of executed instructions also increased a lot, which makes me suspect that there is something i missed
bvt: as far as code speed is concerned, i still don't know whether i fucked up something, or the algorithm is fundamentally slow after some bignum size
mircea_popescu: apparently, the split variant is ~slower~.

asciilifeform: quite likely they have an eventual capitulation to llvm ( and 'unification of the churches'(tm) ) planned as well, but i have nfi what's the holdup there
asciilifeform: the gcc5+ gnomes, occupy selves with cranking out 'mandatory' kludges for intelism; removing backend support for vintage, marginally-sane archs (alpha, hitachi, etc); gluing-with-broken-glass various incompatibilities to prevent coad developed under 5+ from building under 4.x; inserting 'optimizations' that snake around naive cprogrammer attempts at bounds-constraint; and so forth.
asciilifeform: as for gcc, the mushroom let it go in mid-2000s, moar or less.
asciilifeform: Official gcc is , didja know, up to version ~8~ nao. and packed fulla 'beautiful surprises', this is by no means the only 1.
mircea_popescu: nobody gives a shit about "linux kernel", or coc-linux altogether.
asciilifeform: mircea_popescu: it's a google-submitted patch, and it got eaten by the new, 'improved' torvalds, near as i can tell
asciilifeform: whole thrust is to 'nobus-maintain' the scenario where you buy 5 cpu-minutes on lullazon's cluster and get root. rather than to keep neighbouring lullazon-hruscheba tenants from fucking one another
mircea_popescu: haha, what, you compile with the same ~special, purpose made~ gcc flag!!!
asciilifeform: mircea_popescu: observe that all of the various Official 'speculative leak' kludges, ~even supposing they worked 100% of time~, only apply to ~kernel~ -- they do 0 to prevent 'ring3' (luserland) processes from leaking
asciilifeform: the retardation of intel was quite clear even when 386 was being pushed.
asciilifeform: naggum's http://www.loper-os.org/?p=165#selection-85.0-85.510 thing dun merely apply to c. it applies just same to the 'progress' of intel shitirons.
asciilifeform: rright, but to get any actual effect would have to also offer offswitch for 9000 other idjit 'optimizations'
mircea_popescu: rather than "turn it off 78% of tyhe time or so" ?
mircea_popescu: not ffa ; the "lfence" bs i mean.
asciilifeform: it 'works' in the same way as other 'nobus-maintenance' kludges (e.g. koch's 2016 patch) 'work' -- raise bar so that nobus
asciilifeform: mircea_popescu: what would it mean for the kludge to 'work' ? it aint as if x86 actually offers process isolation.
asciilifeform takes the occasion to observe that ffa is 'speculation'-proof, not only in theory but as empirically tested on 7 ( & counting ) intel boxen of various vintages

mircea_popescu: well, i'm not sure what your decision tree is like, exactly. but proceeding logically : 1) it can not be the case cpu is sad on rk ; 2) it is not shown that deffect is organic rather than nsatronic ; 3) the selling point of rk is cheapness/disposability. you can afford to throw these away, unlike an adult server board+deckings.
asciilifeform: but cannot specifically show either way atm.
asciilifeform: given as the other 5 units of pilot plant are still standing, i suspect straight chinese rot, rather than bomb.
asciilifeform: i picked rk orig. not even because of price, but specifically cuz it contains, on the pcb itself, nuffin (known to be) writeable, all of state is loaded from sd and afterwards usb. so i dun expect to be able to tell much from autopsy of the unit, when i get it here
asciilifeform: and we went from there.
asciilifeform: on reset , thing failed to revv up to pingability at all. so i asked for the uart snake.
asciilifeform: previously only ever saw this on boxes with dead disks. what happens there is that sshd eats new connection and then goes to read from hdd and unix eggogs, so it drops
asciilifeform: i asked him to go there when i sat down to make accts for the uy1 people on the thing, and found that : 'ssh_exchange_identification: read: Connection reset by peer'
asciilifeform: a test with independent (from other 5) power supply, also returned same.
asciilifeform: if mircea_popescu or anybody else can think of other interesting tests to conduct on this sad box, i'm all ears.
asciilifeform: notably, a test using the auxiliary (usb2.0) jack returned same result.
asciilifeform: hence why i initially said 'hey, BingoBoingo , loox like another dead stick..'
asciilifeform: dies when kernel begins to load things off the stick.
asciilifeform: possibly as consequence of cleaning, or of the earlier dud drives ( tho none of other 5 were similarly afflicted )
mircea_popescu: that's by far the larger spot. how does this broken cpu get through ddr ?
asciilifeform: mircea_popescu: not only, it does make it to the kernel
mircea_popescu: looky : yet in ~every~ case it initializes the ram.
mod6: Just was wondering if that was somehow making the thing barf.
mircea_popescu: so the init doesn't complete
asciilifeform: initially suspected a dead drive, these produce similar symptoms ( garbage when reading disk ), had BingoBoingo fetch brand-new one from spares stash
asciilifeform: all 4 .txt are from the serial console uart, if it aint obvious
asciilifeform: and in between these actually booted up and ssh-reachable but then panicked in few min
asciilifeform: mircea_popescu: i'ma post lulzdump for the pleasure of mircea_popescu et al in a min.
mircea_popescu: how the fuck would this even work, indulge me. arm processor just invents rng opcode ?
asciilifeform: i'ma have BingoBoingo send me the retired board via snailmails, possibly we find sumething interesting about it
mircea_popescu: i have ~never~ heard of a cpu that ~genuinely~ fandango'd instructions. each and EVERY single one of the ~scant few~ dozen cases was stuxnet-like
asciilifeform: it runs instrs from mask rom on boot, then loads my kernel.
asciilifeform: ok, let's rephrase, there's no detectable fw on rk.
asciilifeform: mircea_popescu: there's no 'fw' on rk.
asciilifeform: mircea_popescu: the idle rk that was to house lobbes et al, has turned up dead.
asciilifeform: mircea_popescu: i strongly suspect that yer right, and the monkeys went 'eh, orcs, what's 1, what's another'
mircea_popescu: asciilifeform what was the rk problem anyways ?
mircea_popescu: am i oversensitive or are the dorks actually trying to pass the guy for guler, on the grounds that "what do ustards know" ?
mircea_popescu: hmmm... i thought i mentioned the fellow.
mod6: Just some food for thought over the next, say, 72 hours.
mircea_popescu: http://archive.is/3cRY7#selection-1855.167-1855.241 << in other lulz, notwithstanding the text, there depicted is ~romanian~ (if the soviet-style ro army uniforms didn't make it plain enough) nicolae ciuca.
asciilifeform: is the reason why asciilifeform went with 'pack as much into ea. 1u x86 as physically possible' when init buildout.
