14:34 mwk: well that took some time
14:36 imirkin_: sure sounds like you had a good time with that
14:36 mwk: lots and lots of statistical analysis
14:43 mwk: I suppose now would be the time to actually use it for celsius T&L sim
14:44 mwk: or, for that matter, do the complete rcp instruction, and not just (1.0, 2.0) range
14:47 mwk: but that'd require me to actually boot up the thing and not just rely on offline datasets collected months ago...
15:26 mwk: eh.
15:26 mwk: translating python to c is hard.
15:54 RSpliet: mwk: no iterative method? That's a quick rcp...
17:09 espes__: mwk: oh cool that's good stuff
17:10 espes__: xqemu's slowly getting hardware tests, will let you know if anything doesn't match up
17:40 mooch2: mwk: nice shit man
17:41 mooch2: espes__, oooooh, where might those be hosted?
17:42 mooch2: i'm uh, pretty interested in x86 emudev

19:36 mwk: RSpliet: that is an iterative method...
19:36 mwk: two iterations of Newton-Rhapson
20:17 Lyude: weird question: anyone know if it's possible to shut off a card on a desktop with nouveau, unhook power/the card itself and hotplug another one?
20:17 imirkin_: sure - just have to have a motherboard that supports this.
20:18 Lyude: this one -supposedly- does
20:18 Lyude: but it won't kill anything?
20:18 imirkin_: must be extremely high-end
20:18 Lyude: nah, it's just an amd board :P
20:18 imirkin_: then it almost certainly does not
20:18 Lyude: you sure? there was a bios update that went through for it that specifically mentioned pcie hotplugging]
20:18 imirkin_: i've heard of it in the context of the NUMA-type stuff people do
20:18 mjg59: If it's a real PCIe hotplug port then sure
20:18 Lyude: (this is ryzen also)
20:18 mjg59: The OS will get notified
20:19 imirkin_: pcie hotplug isn't the same as physicall removing the thing
20:19 Lyude: ahh
20:19 imirkin_: physically removing the board means that the electricals have to be set up for it
20:20 imirkin_: pcie hotplug can happen any number of ways, including having an adapter card with a bridge for the laptop-type pcie card
20:20 airlied: also check it's pcie hotplug on all pcie ports
20:20 mjg59: Lyude: For a real PCIe hotplug port there should be some sort of button to inform the OS that it's going to be unplugged
20:20 mjg59: Surprise unplug doesn't tend to end well
20:20 Lyude: ahh, I see
20:21 mjg59: What's the board?
20:21 imirkin_: i think you can do it with whatever the successor of PCMCIA is
20:21 imirkin_: [surprise unplug]
20:21 mjg59: Expresscard, yeah
20:21 Lyude: Product Name: A320M GAMING PRO (MS-7A39)
20:21 Lyude: (MSI)
20:22 mjg59: Yeah no mention of hotplug in the specs
20:22 mjg59: Just that firmware update
20:22 Lyude: huh, weird
20:22 mjg59: There may be board-level stuff that makes PCIe devices appear/disappear
20:22 Lyude: ahh
20:22 mjg59: But I'd be surprised if the ports are physical hotplug ones
20:22 imirkin_: i've only heard of boards like that existing tbh
20:22 imirkin_: never seen one actually on sale anywhere
20:22 mjg59: imirkin_: It's mostly server stuff
20:23 imirkin_: even with server stuff - haven't seen it
20:23 mjg59: Swap out bad parts without taking down the system
20:23 imirkin_: yeah, i understand how it'd be useful
20:23 imirkin_: i just haven't seen it in any server parts :)
20:23 airlied: imirkin_: do you buy server stuff like you but nvidia gpus?
20:23 imirkin_: no, i pay actual money for servers, not $10 like i do for nvidia gpu's
20:24 imirkin_: but nothing super-high-end, in fairness
20:24 imirkin_: definitely nothing over $15k/machine
20:24 airlied: also looks like the cards need to support it
20:39 karolherbst: Lyude: you can use bbswitch on prime sytems
20:39 karolherbst: ohh wait, forget that comment
21:01 mooch2: imirkin_, how the fuck do you only pay $10 for nvidia gpus???
21:08 gnarface: well anything older than the 500 series is utterly useless to a windows user
21:08 gnarface: since they can't even get a driver for it
21:08 gnarface: so it's easy for me to imagine that those cards can be bought used cheap
21:20 mwk: mooch2: buy old and low-end ones...
21:39 mooch: ah
21:39 mooch: i have a newish midrange one
21:39 mooch: only cost me $70 :D
21:39 mooch: for a 750ti to be precise
22:05 imirkin_: mooch: i've splurged as much as $30 on some boards, in fairness
22:05 imirkin_: but yeah, old and low-end :)
22:06 imirkin_: although i got a GT215 with GDDR5 vram, which is pretty fast, and a G92 Quadro which is nice too
22:39 RSpliet: $15k gets you an awful lot of machine... if you don't mind it being ex-facebook stock
22:40 imirkin_: one can easily go to $200k/machine... once you throw 1-2TB of ram in there
22:41 imirkin_: and naturally you have to fill all 4 sockets to host that much ram...
22:42 RSpliet: imirkin_: if you can settle for a 5yo 256GiB and 8*E5-2665 you can be done for just over $2k
22:42 imirkin_: erm
22:42 imirkin_: for 256G ram?
22:42 RSpliet: http://natex.us/2u-dell-poweredge-c6220-4x-dell-0tck99-nodes-8x-e5-2665-sr0l1-256gb-32x8gb-ecc-pc3l-10600r-ram/
22:43 RSpliet: As I said, ex-facebook (or sth) stock
22:43 imirkin_: oh wait
22:43 imirkin_: this is a multi-node thingie
22:43 imirkin_: so it's actually 4 servers
22:43 imirkin_: still, cheap
22:44 RSpliet: yeah... a shame you can't stick 1GPU per node and have them render in SLI
22:44 RSpliet: (... no, I'm not serious :-D)
