mircea_popescu: diana_coman right on schedule!
mircea_popescu: ftr, warlock has the stronger troops for large maps ; sorceress for medium. if you're looking for a shortcut to beating his ass.
asciilifeform: was astonishingly well-balanced game, imho
asciilifeform played it with brother
asciilifeform: btw, bvt , rax etc. ~are~ encoded as 1-8, the iron dun see reg names at all, the classic names are a convention of the asmers and the vendor docs. and imho remains on acct of the asinine x86isms like MUL which use fixed input and output regs, makes'em slightly easier to remember.
asciilifeform: if you ever wonder why your x64 iron draws 50x the wattage to do same thing as e.g. rk, wonder no longer -- the insanity where shit gets moved around to accomodate idjit instructions with fixed in/out hoppers, the insanity where you gotta set prefixes to specify what width ~each operand~ is (why this is needed ? srsly) , all of this adds up to 3bil transistors that heat the room
asciilifeform: ( and this is not even touching the subj of the tlb cache, which is ~1/3 to half of those transistors , which we have on acct of the idjit paging scheme )
asciilifeform: when you build 1 of these things, there's a set of decisions that end up determining shape of whole thing; and it so happens that intel made ~all~ of the most retarded possible choices.
asciilifeform: aaand this is not even to mention their seekrit 'optimizations' behind the scenes.
trinque: diana_coman, other folks that have cuntooed, can y'all confirm that the paths that ended up in your genesis.vpatch do not in fact exist? I'd like you to reproduce the commands starting at line 114 of scripts/make_portage_tree.sh in your build directories, i.e. cd ~/src/cuntoo/build/cuntoo and then run them, as root
asciilifeform: it is such a retarded design that even intel and microshit ~tried to escape~, in 1990s. but nsa decided that it ~likes~ x86 , and for it to remain cemented standard , on acct of http://www.loper-os.org/?p=1299 .
trinque: the paths ending up in your genesis vpatches are hard to blame on my script, rather than a difference between our vdiff executables.
trinque: the remainder of work here is resolving this issue (I have not had) with paths, after which we can start producing ebuilds for novel republican work atop the genesis.
trinque: http://btcbase.org/log/2018-12-03#1878057 << I am currently running a build with a vdiff pressed to same. The only difference is that I have altered the gpr files to statically link.
a111: Logged on 2018-12-03 21:48 diana_coman: hm, if it's indeed the tmp thing, it might be worth a try to press vtools to current leaf (i.e. vtools_tempfile_standalone or _notmp) and see if that cures it; my archive contains pressed vtools to ksum patch only, not further
asciilifeform: in lulz inspired by bvt's article, asciilifeform went and dug re 'modern' cpu arithm instructions, and found https://lemire.me/blog/2018/04/19/by-how-much-does-avx-512-slow-down-your-cpu-a-first-experiment/ << intel's crud apparently ~drops frequency~ if you use'em , ultimately nuking all gains from doing so ( they want you to use, so as to shit out binaries that crash on amd, but really gains 0 )
asciilifeform: i.e. they can't stuff any moar transistors in there, and end up offering the equiv. of ye olde 'winmodem'
asciilifeform: where yes it'll do a e.g. 512-bit add, but -- evidently -- using ~existing~ regs, and putting out same (or greater) amt of heat, and locking up the pipe
asciilifeform: bvt: the only new instrs that seem to be even theoretically of use, are 'mulx' and 'adcx' -- but i dun have any iron that supports these atm, and cannot even begin to say whether constant time etc
asciilifeform: http://p.bvulpes.com/pastes/ncZvu/?raw=true << details, for anyone who gives a shit
asciilifeform: http://www.loper-os.org/pub/amd64_mulx.jpg << amd seems to support ~currently~, but dun say from what date of chip specifically
asciilifeform: fwiw it's still a 64bit mul, the only win is that it dun set any flags (and therefore keeps the pipe flowing)
asciilifeform: ftr asciilifeform suspects that 99% of what can be won from asmism in ffa, can be had simply from bvt's existing 64bit mul, plus doing adc for the additions-with-carry instead of the manually-cranked carry calc, and that all 'fancy' instructions will only lead to sad
asciilifeform meanwhile found today mistake in 17 , and expects it'll take several days to rewrite
asciilifeform: and meanwhile2, we have answr to above quandary, 'In 2017, BMI2 was further incorporated in AMD's Zen-architecture...'
asciilifeform: ... so 'mulx' aint in anyffing i have. if someone wants to test it with own hands, he can, otherwise fughetit.
asciilifeform: ftr an 'iron ffa' cpu does not even require a massive multiplier . even a microcoded ffa-style thing that lets you specify 'and at memory x there is a w-word int, and at y a w word int, add'em' etc , would still massively win over the extant liquishit, it would do the arithm atomically, without invoking branchpredictor, losing cache, etc.
asciilifeform: but no prizes for guessing why it aint on the market.
asciilifeform: ( 'you want fast crypto, plebe? here, buy nsa-certified(tm)(r) cryptoaccelerator card from ibm' )
asciilifeform: remember, only a terrorist(tm)(r) 'writes own crypto', 'good citizens use openssl' etc etc

mircea_popescu: but on a more optimistic note, that's probably the most anyone cared about anything to do with the topic or the persons named or otherwise referred to in their entire history. that should count for something.
mircea_popescu: http://bvt-trace.net/2019/03/ffa-chapter-9-homework-comba-in-x86_64-assembly/#selection-15.295-19.176 << why this, specifically ? is there no ada asm calling method besides this ?
mircea_popescu: 7% gains, not even that huge.
mircea_popescu: but speaking of those design decisions, by my current thinking the ideal processor is defined as follows : the bus width is 512bits ; therefore the byte is 512bits. the processing core is a state machine, with 512 byte-sized registers. a processor is composed of 512 + 8*9 such cores. for convenience imagine them organized in a cube, 8x8x8, with an extra 64 item layer on three sides.
mircea_popescu: the 512 "central" cores are state machines that can do add or mul, and always proceed ~on their entire register set~. so if you don't want to multiply 131072-bit numbers, just put in zeros ; and if you put larger numbers in there you'll just get the LAST 262144 bits of the result, is all.
mircea_popescu: the 64 "flat outer" cores are state machines that can do mvin and mvout -- taking registers to memory or memory to registers, ie use the bus. only, of course, for the state machines inside their ~projection~.
mircea_popescu: the remainder 8 "sharp outer" cores control the flats, by moving things in and out of ~their~ registers.
mircea_popescu: memory, of course, starts with byte 299008 (584 * 512) and extends as far as 512 bits bus can address, if you're installing that. meaning, all core registers are allocated as memory anyways. and that's fucking it.
mircea_popescu: i ~can't imagine~ what the fuck must have been going through the skull of whoever came up with "working a piece or moving the worked piece, same thing". what the fuck ever is it same thing!

asciilifeform: the thing with gigantic multers is that they grow physically with the cube of the bitness. hence scarce. ( tho i dun imagine even a 8192bit single-cycle multer would be remotely near as heavy as the 3bil-transistor 'let's fry eggs' pentium-xxviii or whatnot )
