gregorynyssa: asciilifeform: are you saying that 32 Opteron cores are required to decrypt Serpent at line-rate?
asciilifeform: ( per asciilifeform's napkin calcs, already current protocol, even in a hypothetical 'tight' compiled impl., will need 32 'opteron' cores to actually eat at 1g/s )
asciilifeform: http://logs.nosuchlabs.com/log/asciilifeform/2022-06-30#1109620 << well, cars (lappies) and 'belaz' (proper comp, w/ opterons etc)
asciilifeform: 1 of the reasons asciilifeform still uses exclusively amd 'opteron' in x86 boxen
billymg: $125 for the board, chassis, and two opterons
asciilifeform encountered this kinda thing many times, but typically on the ancient opterons he uses, where capacitor plague, rather than new laps
asciilifeform: mangol: it was not a successful experiment in that the emulated machine runs (on 2010s 'opteron') at roughly '486 dx' speed
asciilifeform would still not refuse 'minix w/ tcc' if could be stood on 'opteron' and run x, emacs, sbcl, etc
dulapbot: Logged on 2020-12-21 19:54:39 asciilifeform: will prolly try the infamous kdpe-d16 next. this an' the other one, were the last 2 opteron+ecc mobos before the great fritzchipping.
asciilifeform regularly inhabits not-so-recent irons, e.g. kgpe-d16 opterons, x60 lappy, similar

asciilifeform: i.e. if yer in bingostan and you want, say, 'opteron' -- now you need to hire someone to smuggle it in. or pay its weight in silver at customs. or i suppose if you own a uboat...
asciilifeform: verisimilitude: you know those 32core ecc ram 'dulap' opterons i offer customers at my isp ?

asciilifeform understands perhaps better than most, the fact that baking pcb in small runs is costly. but at same time not eager to pay opteron workhorse price for the equiv. of a rk.
asciilifeform: trinque: iirc the 'unmatched' came up last yr in a thread -- it's rk-level box -- but priced (new) like the princely 32core vintage opterons i've racked
trinque: yep, unsurprising. the cheapening of industrial processes was already rolling well before the time of opteron

asciilifeform: ( recall, orig. objective of experiment was 'can haz libless 100%-asm proggy that's guaranteed to boot a usable linux in 100% isolation on any 2.6 x64 linux'. rather than 'can turn a 300watt opteron into the perform. equiv. of 3watt 'pic32mz'' lol )
asciilifeform: i.e. on 3GHz opteron -- you get equiv. of ~100MHz mips...
asciilifeform: ( on 3GHz opteron, M-linux runs at roughly speed of 486DX2... )
asciilifeform: gregorynyssa: lol, what 'better documentation' ?! i have a shelf-sized full set o'docs for opteron + their gpu. where do i get intel's ?
asciilifeform: in ffa tests, gets approx. 1/2 the performance of asciilifeform's opteron. which on <5watt is imho nifty.
asciilifeform: that was dead end experiment tho, 'run at 486 speed on opteron'.
asciilifeform: the other possib. choice, afaik, is 'now i have editor, compiler, kernel, that'll run for so long as my stash of opterons lasts, oughta be good for 40yrs' and 'let's design new irons'
asciilifeform: arguably not so interesting given as 'coreboot' traditionally has simply 'ret' in its smm handler; and afaik on all opterons where can connect 'sage', can emplace 'coreboot' in place of heathen bios.
asciilifeform: unrelatedly: folx interested in smmism (smm was how boobytraps were often implemented prior to proper fritzchip) will find that it is detailed in amd opteron datashit; and that you can singlestep smm handler w/ 'sage' probe on irons where there is connector for same.
diana_coman: asciilifeform: leased opteron, yes; not via deedbot, no; just went according to "if not the right thing, than the cheapest thing".
asciilifeform: diana_coman: i cannot resist to ask, didja after all discover a rack shop that'll opteron for btc via deedbot ? are these public, can i also buy? (could use spare mirrors...) or is a custom deal that you brokered ?
asciilifeform: i.e. leased opteron ? neato
diana_coman: asciilifeform: no; I did get though an opteron.
asciilifeform: BingoBoingo: for instance, i bought 4 fg , wrapped in opterons, for 22m. jurov meanwhile bought 4 fg wrapped in cellophane for 40m. why not occurred to jurov to buy the former and offer BingoBoingo 1m to detach fg and have the remainder pissed on & set on fire... ?
asciilifeform: BingoBoingo: it's identical to dulap-primary, but w/ exception of ~8~ disk slots and dual ps. ( i.e. 2.3GHz x 32core (Opteron 6376) , 256G ram. )
asciilifeform: hypothetically, a pc mobo designed for classic opterons, w/ a heavy aluminum ground layer , designed to be sat down on top of a 1x1metre hedgehog, would do the job. but of course dun exist presently.
asciilifeform: at any rate, currently 'workstation' to me means at least 2 pre-2013 opterons. and swappable nics , as cards. and expandable ecc ram.
asciilifeform: the classic opterons included 0 oddball on-die periphs (nics, remote managers, etc) unlike the newer, and have published init code. so hard to picture of what would consist an effective mine in'em
dllud: Did someone do it for the Opterons?
asciilifeform: but unlike e.g. the opteron -- given the cost, nobody's likely to ever pull ibm's apart.
dllud: Yes. But I can argue the same about the old Opterons, can't I?
