asciilifeform: mp_en_viaje: thinking about it moar, i suspect that it is possible to bake a less screamingly retarded version of bellardism , where, e.g., the 'cache' is prefilled with unconditional jumps to the sim-instructions, eliminating the decode hit
a111: Logged on 2019-07-22 22:56 Mocky: lobbes if you want to relocate 3 hours east, 90% chance I can get you a job in Ral, I have a spare room you can stay in while you look for a place, ditch the dysfunction, we'll find new girls
lobbes: http://btcbase.org/log/2019-07-22#1924303 << I appreciate this offer, ty. I've got my living arrangements and job situation under control for the short term, BUT once this is done I may indeed take you up on your offer re: finding girls. Been poking around the internet and well, it is still a shannonized ocean of wtf in this regard. ☝︎
a111: Logged on 2019-07-22 20:12 mp_en_viaje: lobbes, you'll live. anyway, get that thing published so others can patch on it and thus lighten your own workload!
lobbes: http://btcbase.org/log/2019-07-22#1924301 << roger that. I'll aim for this weekend to get it published ☝︎
asciilifeform: all of this is 1) exceedingly gnarly , from 'fits in head' pov 2) requires a writable-and-executable memory segment. i.e. massive open wound.
asciilifeform: and as it goes, tries to keep cache full, does equiv. of 'prefetch' (if this were a normal iron cache), etc
asciilifeform: this then executes.
asciilifeform: they used 'dynamic recompile' method, where the sim simulates a kind of cache. when sim-instruction fetched, it looks whether found in this cache, and if not, emits a chunk of x86olade into said segment of cache, which corresponds to 'compiled' ver. of that instr.
asciilifeform: for thread-completeness, i'ma summarize how bellard et al did it
asciilifeform: in the actual instrs. per se (see 'mipsinst' dir.) , used conditional mov's wherever could think of how, so as to also keep pipeline full
asciilifeform: seems like there is only so much 'silk purse' that can be made from this particular sow's ear.
asciilifeform: best i could think of , was to arrange the mov.../and.../shr... etc so as to occupy the amd64 pipeline properly, in each inst. form.
asciilifeform: ( at least not on my opteron, on 2014+ theoretically could, but i dun buy those )
asciilifeform: in the beginning, thought i could at least implement the mips instruction operand decode using xmm. but ha! not that either.
asciilifeform: to add insult to injury, asciilifeform knows how to represent 'x bit lookup from x*k-bit string representing table' via arithmetic methods -- but! amd64 dun let you do full arithmetic on xmm either ☟︎
asciilifeform: ( for n00bz / tlbism (aka mmu) is how os gives individual userland process the illusion of 'infinite memory, starting from addr 0', paging, etc )
asciilifeform: kernel-mode coad btw bypasses the tlb, so runs with the expected ~40x slowdown.
asciilifeform: closest thing to likbez.
asciilifeform: mp_en_viaje: well, on my opteron, they're 128bit regs (on moar recent -- 256 and even 512!) but only the lower 64 is directly addressable. and gives buncha 'simd' ops, e.g. 'shuffles' where 'take erry 7th bit and add'em' etc. but looked and looked an' found nothing that'd correspond to table lookup
asciilifeform: world's most retarded machine arch, the pc is.
asciilifeform: originally was at least gonna park the tlb ~in~ the xmm regs. but guesswat, there aint even a way, in 1 clock cycle, to get anything other than low 64bit out of'em !
a111: Logged on 2019-07-24 08:25 mp_en_viaje: is there no way to fix the lookup ?
asciilifeform: http://btcbase.org/log/2019-07-24#1924463 << on the actual iron, it happens in 1 clock cycle, cuz entirely parallel. in 'm', ends up iterating through all 16 tlb entries. i looked into using 'simd' instructions to do it, but they are ~artfully~ useless , ended up using the xmm regs strictly as fast temp storage; ☝︎
asciilifeform: grr phf is it gonna take 2 months for the thing to be in btcbase.org/patches so i can link to it ?! ☟︎
asciilifeform: the way i was gonna implement the nic, is to pipe packets via linux's 'tap/tun' into a slot in the 'm' mmio space (see bus.asm) and generate slave irq (see irq.asm) . if these arrive faster than the irq can be eaten, they simply get dropped.
asciilifeform: http://btcbase.org/log/2019-07-24#1924470 << the sheer waste of current aside -- not sure that ~this~ : let's gedankenexperiment, and picture a 'M' running apache, under ddos: ☝︎
mp_en_viaje: actually come to think of it, fuck that, ima put this in the bylines.
mp_en_viaje: there just is nobody the fuck else, not even fucking close, nor ever was. and we're not even discussing ~range~ here, the fact that i'm one and these are legion. we're simply saying that out of all humans who ever lived, nobody came even close in any way and on any direction. i own erotica like zeus owns olympus.
a111: Logged on 2019-07-24 08:48 mp_en_viaje: which 4. made me exclaim "what the fuck is wrong with these idiots, ~I~ am the world's greatest erotica writer, and by such a fat margin that if i were the mvp of the winning team, nobody else writing erotica would be even good enough to be accepted as last choice in one of the feeder clubs of the conference's weakest team.
mp_en_viaje: http://btcbase.org/log/2019-07-24#1924476 << this, btw, includes all, living and dead, from d. h. lawrence to whoever the fuck you wish to pick, salo 0.1 marquis de sade, jane austen, WHOEVER wilkes, beerbohm, ☝︎
mp_en_viaje: and no -- no apologies for log clutter ; this imo is the exact opposite of log clutter. this is because there are no spurious details included -- if it's long, it's because the point is intricate.
mp_en_viaje: so there you go, i'd rather read you than A. N. Roquelaure ; and this isn't a rhetorical turn of phrase, it is literal description of actual historical occurrence.
mp_en_viaje: because "works for me" ain't the fucking criteria of goodness. mp being able to read through the thing, ie, CORRECTNESS, is the criteria of goodness.
mp_en_viaje: this read mechanically failed ; i have no qualms with whoever managed to jack off to anne rice nevertheless -- but it is NOT good. even if it works for you. ☟︎
mp_en_viaje: 6.d.II. wtf is "darkly yellow" ; 6.d.III. wtf is "curlier than perfectly straight" ; 6.d.IV. you DO NOT wish to have her arms "covered in hair" ; then he proceeds to 6.d.V. "cut her sleeves" in the very next line, notwithstanding she was saying "arms" here, and well, i can not read this.
mp_en_viaje: 6.d. "Her ni**les were a rosy pink as were her lips, and the hair between her legs was darkly yellow and curlier than the long straight hair of her head, which covered her arms almost down to her hips on either side of her." actually killed the read, because 6.d.I. the rosy pink of the lips is NEVER THE SAME as the hue of the lips, this is 9yo coloring ; yet I have seen four digit young cunts and the two hues are alw
mp_en_viaje: 6.c. "her embroidered gown had fallen deep into the crease between her legs so that he could see he shape of her sex beneath it" produced the protestation that this woman has never seen embroidery (or, i guess, never seen girls in work out pants without panties).
mp_en_viaje: , five words like that.
mp_en_viaje: 6.b. "Her face was perfect to him" provoked protest because it's a cop out : the woman "kills two rabbits with one stone", by avoiding BOTH the work of describing her face, AND the work of explaining credibly why these two like each other. yet the job of the writer is 100% and precisely NOT to make this deal ; because if they make it, even once, then their story inescapably becomes "this is a good^H^H^H^Hgreat story'
mp_en_viaje: 6.a. "And approaching her, he gave a soft gasp as he touched her cheek, and her teeth through her parted lips, and then her tender rounded eyelids." sparked protest because ~everyone else~ is fucking decrepit and gaunt and dusted over in spider webs, so the disparity provokes in me the expectation a spider's jumping right out, antisexual 100%
mp_en_viaje: so she found me a copy, and 6. i proceeded to read. and i ran into bounty aplenty, such as :
mp_en_viaje: which in turn 5. provoked girly to mention anne rice, because whatever, as a virgin tween she got really hot and bothered over the princess getting sold by the prince to some merchants who stuffed her cunt fulla figs and such things.
mp_en_viaje: which 4. made me exclaim "what the fuck is wrong with these idiots, ~I~ am the world's greatest erotica writer, and by such a fat margin that if i were the mvp of the winning team, nobody else writing erotica would be even good enough to be accepted as last choice in one of the feeder clubs of the conference's weakest team. ☟︎
mp_en_viaje: d Reluctant Bondage-Sex Encounter Between Stepdad and Daughter", The world’s greatest erotica writer, Kelly Leigh proudly presents "Take It For Daddy" – Incredibly hot sex stories featuring stepdaughters and their stepfathers!
mp_en_viaje: (what happened was that 1. i was looking through search results for "daughter encounter", the why we'll not include as we can't regress this storytelling forever into endless past ; and then 2. ran into dude killed for being dude, which i suppose is kinda sad, but w/e, america rite ; and then 3. fell on "Take It For Daddy: A Rough an
mp_en_viaje: asciilifeform, don't feel too bad, this isn't "sad" just because not obviously useful ; it's glorious, because correct. id much rather read this than w/e, say yest's attempt at the claiming of sleeping beauty.
a111: Logged on 2016-09-23 13:59 mircea_popescu: they ddosed trilema, qntra etc - nothing happened ; they had their agent ddosed - that's the end of the road for him.
a111: Logged on 2019-07-24 01:44 asciilifeform might even be wrong, and it is conceivable that 'dhrystone of pentium166 but i/o of opteron' actually suffices to e.g. host blogs.
a111: Logged on 2019-07-24 01:22 asciilifeform: mod6: i was gonna genesis a kernel for that thing, but nao after sad benchmark thinkin', it's of ~0 use outside of very specialized applications
mp_en_viaje: i dunno how exactly you came up with some magic incantations that'll make it okay. however, to repeat this the 5th or so time : there is no magic ; it did not make it okay. ☟︎
a111: Logged on 2019-07-24 00:58 mod6: (My apologies for the delayed response). Anyway, long story short, we're in a bit of a holding pattern on new vpatches atm.
mp_en_viaje: is there no way to fix the lookup ? ☟︎
a111: Logged on 2019-07-24 00:11 asciilifeform: i'ma let BingoBoingo think re whether it makes sense to offer shared hosting on a thing like that. (or whether folx will simply die of laughter)
asciilifeform off to wipe sad chalkboard , and then meat.
asciilifeform: esp. w/ trimmed userland.
asciilifeform might even be wrong, and it is conceivable that 'dhrystone of pentium166 but i/o of opteron' actually suffices to e.g. host blogs. ☟︎
asciilifeform: ( for that matter -- if e.g. mp_en_viaje one day bakes actual silicon cpu , would run on par with pc, with unchanged soft. )
asciilifeform: to round off that thread -- asciilifeform strongly suspects that kernel would run 100-200x faster on the 10 $ 'ice40' than on opteron-cum-'M'
mod6: Seems hard to imagine, ya.
asciilifeform: conceivably there is a use for e.g. cuntoo that loads from memory snapshot in <3sec but runs 'like pentium 166'
mod6: yeah, oof. I saw your post re-'M', will try to read through here soon. I did see your benchmark comments above tho.
a111: Logged on 2019-07-18 05:03 asciilifeform: at some pt somebody's gonna have to audit a snapshot of bin gnat. which wouldja rather ?
a111: Logged on 2019-06-04 00:51 asciilifeform: incidentally, i generate these by machine, and it takes about 3sec per. would have put it as a net-connected hopper thing aeons ago, BUT it of course uses a heathen render (there are no 'demonstrably electrically correct' pdf eaters, and i dun expect one to exist) and suffers from the obvious problem
asciilifeform: mod6: i was gonna genesis a kernel for that thing, but nao after sad benchmark thinkin', it's of ~0 use outside of very specialized applications ☝︎☝︎☟︎
mod6: In a few days, once I'm caught back up, if still no one has tested this, I'll give it a try.
a111: Logged on 2019-07-08 04:01 mp_en_viaje: meanwhile speaking of http://bvt-trace.net/2019/07/vdiff-vpatch-blockwise-keccaking/#footnote_0_42 would someone look at that ?
mod6: thanks asciilifeform! Just trying to catch up on logs/blogs atm. Been behind all month!
mod6: (My apologies for the delayed response). Anyway, long story short, we're in a bit of a holding pattern on new vpatches atm. ☟︎
mod6: http://btcbase.org/log/2019-07-19#1923606 << This is a neat-o vpatch 'who gave', but it came in just after the 'NO NEW WORK IN SHA PLOX'; so there are a few like this that probably will go into TRB main Vtree once the Lordship reviews/audits the proposed Keccak TRB Vtree; perhaps possibly after TRB has a new home OS/environment. ☝︎☟︎
asciilifeform: ^ figure on properly unloaded box, vs. earlier; ~= 252.3x slower than host on same benchm.
asciilifeform: ( if anyone finds -- plox to write in. )
asciilifeform: to be pedantically exact : 66.35 'bogomips' (on 3GHz opteron) , and published table gives e.g. 'Pentium/166 66.36'. i was unable to find similar table of classics for 'dhrystone' .
asciilifeform: i/o, however, is only ~4x slower than host's, so in fact one ~could~ run e.g. trb on it.
asciilifeform: afaik this is the 1st attempt to measure it, too ( i.e. with max sweat over cycles, 0 c in proggy, 0 libs, etc sim. )
asciilifeform: seems like ~this~ is the actual (vs. 'i-can't-believe-it's-not-butter' vmware et al) cost of 100% process isolation on pc.
asciilifeform predicted initially that cost would be ~40x vs host, based on avg. # of x86 instrs. taken per simulated instr.
asciilifeform: i'ma let BingoBoingo think re whether it makes sense to offer shared hosting on a thing like that. (or whether folx will simply die of laughter) ☟︎
asciilifeform: (actual iron does it in O(1), emulated -- naturally in O(N), where N is up to all 16 entries in tlb table)
asciilifeform: most of the 'ding' is in the tlb lookup .
asciilifeform: meanwhile, in measurements : performance of http://www.loper-os.org/?p=3420 system : as measured by a) 'bogomips' (linus's benchmark) : 93.4 times slower than host cpu; b) 'dhrystone' (traditional integer benchmark) : 300.98 times slower than host cpu.
