dub: somebody said
that once you have a design applying it
to 'smaller process' is easier?
Namworld: I am
torn right now, by my will
to secure a profit right away and how good ASICMINER seems
to be
turning out.
Namworld: I guess
the competition will be an important impact
Namworld: If
they stick around for at least a year mining and selling ASICs, I guess... more if
they design new chips in
the future.
dub: you would have
to assume asicminer got
their boards hashing individually before racking
them up
Namworld: You sure it's going
to be rentable?
Diablo-D3: Namworld: hahahaha I made
the list short
pigeons: another one I wonder about is deepbit reclaimer asics where you buy
the shares at icbit.se
midnightmagic: pigeons: Originally, 200+ share owners for asicminer were planned
to be able
to
trade-in and get an asicminer. I don't know what's happening with
that deal
these days.
midnightmagic: Bugpowder: From a purely economic sense. *Some* people just want
to participate more as a miner, and get pristine coins.
Bugpowder: Although,
the best use of fiat was
to actually BUY bitcoins instead of mining equipment
midnightmagic: On
the bright side, I heard back from
them and
they
told me
that Icarus owners get
to jump
the line. :)
Namworld: It's a long
term profit share of an ASIC manufacturer
Bugpowder: AND you could
then put
the proceeds on NO on
the BFL bitbet
to increase it even more
midnightmagic: Diablo-D3: Jeff said when he gets it cooled properly
the reboots ease up.
Bugpowder: it is more money
than you would make by holding
the shares and recieving dividends
midnightmagic: Diablo-D3: I'm really hoping it's not
that sensitive
to heat. Because
that would suck..
Diablo-D3: instead of just handling it normally,
they reboot
the whole box
Diablo-D3: I
think
they did
the fault detection shit wrong
Diablo-D3: midnightmagic: I dont know why
the reboots are happening
midnightmagic: Diablo-D3:
Their changes
to cgminer I'm personally most interested in.
Namworld: BFL might still save
their face and just be really late incompetents.
midnightmagic: Diablo-D3: Yeah me
too. And
they're not fully functioning. Have you been seeing all
the reboots Jeff's unit is doing?
Diablo-D3: midnightmagic: dude, I really doubt
they made 2 fully functioning machines like
that
midnightmagic: Diablo-D3: Also, Yifu said
the source would be published ages ago, but I don't see it.
midnightmagic: Diablo-D3: I don't hear about anyone else receiving
their units.
midnightmagic: If
the others never ship, asicminer will have enough hash
to 50%, and asic doomsday will happen.
Diablo-D3: Namworld: bfl probably wont, and basic failed
to ship
Namworld: If
the others never ship, I'll be pissed.
Diablo-D3: midnightmagic: anyhow, whatever. if numactl says its numa, its probably numa, and I was
tired of
this argument long before gmaxwell freaked out
pigeons: i
thought you meant "consumer asic mining devices"
Diablo-D3: Namworld: and where are you selling
them?
Diablo-D3: midnightmagic: wont be with
this batch
Namworld: Because
they're already on auction
Namworld: I
think my ASICMINER shares will be sold =/
Diablo-D3: midnightmagic: as a programmer, Ive basically rejected
threading altogether
Diablo-D3: Namworld: yeah, I
think
thats awesome
midnightmagic: Pretty much every processor
that can be used in a multi-socket machine now benefits from a NUMA-aware Linux.
midnightmagic: And.. almost every other machine
that has a multi-socketed processor where each processor has a mm onboard and hands out memory
to other processors over an interconnect.
Namworld: Now
that's what I'm
talking about
Diablo-D3: midnightmagic: Im
talking in genral
midnightmagic: I'm
talking about
the one I'm currently logged into.
midnightmagic: Ah, you're
talking about your own machine, not
the one I'm currently logged into right now.
Diablo-D3: midnightmagic: its not common for machines
to have more
than one northbridge
dub: Bugpowder:
they should
take it
to #bitcoin-bromance
midnightmagic: You mean super common amongst processors
that have individual MM.
Diablo-D3: midnightmagic: and btw,
that 8 core box I described, Im pretty sure it had a northbridge for
the second ring
Diablo-D3: and due
to how its constructed, yes, using it as numa is a better use of it's resources
Diablo-D3: huh?
the only
thing you've done is found a box
that qualifies
to be called numa
midnightmagic: No, really. Did you just make all
this up and
then got surprised so you have
to defend it by pretending "node" in
the literature means something other
than what it does?
Diablo-D3: no, I
thought moore was
trolling me
midnightmagic: I don't know enough about
that
to meaningfully discuss it with you.
Diablo-D3: compute units actually have local memory, and individual
threads have local memory on
top of
that
Diablo-D3: yeah, but Im just
talking
the gpu accessing vram
midnightmagic: Taken as a unified whole, any processor "accessing" other memory, regardless of whether
the system has
to *push* memory out
to a GPU and act as an interloper, means it is non-uniform memory access.
Diablo-D3: midnightmagic: Im
talking just from
the perspective of
the gpu
midnightmagic: It is much slower for
the CPU
to access
the memory of a GPU, and
thus by definition it is also non-uniform memory access.
Diablo-D3: actually, I wonder if it does really qualify
to be called
that
Diablo-D3: the majority of memory isnt local
to compute units
Diablo-D3: are
they NUMA
too? your definition seems
to fit
that even
though its really wrong
midnightmagic: I'm fairly sure
that speed of memory access is
the only qualifier.
Diablo-D3: if amd ever fixed
that, you might end up with a non-numa supercomputer.
Diablo-D3: they dont when
they're on other sides of an htx bridge
Diablo-D3: opteron memory controllers
talk
to each other
to synchronize various
things
midnightmagic: I know you don't log, but even in your scrollback, I'm fairly sure you can't find a quote from me where I asserted
that.
Diablo-D3: midnightmagic: and btw, it works
the other way
midnightmagic: The definition of NUMA is non-uniform, it's in
the acronym.
Diablo-D3: midnightmagic:
thats not
the way I interpreted
that
midnightmagic: I'm fairly sure he's limited it
to
the definition of NUMA.
Diablo-D3: not only does
that program slow down, but it assrapes
the entire machine
midnightmagic: 11:30 < moore> and when you have non uniforme access
to memory like in a multi socket system it is nonuniform
Diablo-D3: you have
to be very careful not
to use anything
that uses
threads and/or isnt numa safe
Diablo-D3: I'd hate
to own
that machine
though
Diablo-D3: and I believe I also said
that opterons with htx bridges are numa
midnightmagic: Except
that I have a machine
that AMD calls NUMA
that I'm logged into right now.
Diablo-D3: I dont, I just dont like people claiming anything with more
than one socket is numa
midnightmagic: Right, it's so alien, it's
the ONE EXCEPTION
to your definition.
Diablo-D3: they built
two circular rings,
then added
two bridges where
the crosses would go

Diablo-D3: so
theres an htx bridge somewhere on your mobo
Diablo-D3: midnightmagic: I
think I know why it has numa enabled
midnightmagic: It's an Opteron 854 based machine. Opteron 854s are single-core. You
tell me how many sockets.
