<0> gimp - yeah, all this on .90 nm.
<1> yea
<0> just wait till their .65 nm chips. :D
<1> intel is boned
<0> intel is seriously looking weak right now. :D
<1> the server socket looks wild
<0> o p t e r o w n a g e
<1> 1207 pins heh
<0> ok off to a meeting. back later.
<1> i had no idea quad core was coming in 2007
<2> I wonder how they will deal with cache coherency chatter overhead in larger scale N-way opterons ? even on a 4 chip opteron 8xx the bus overhead from coherency cycles is quite large.
<1> i'm sure that was part of the core redesign when they went to ddr2
<1> but, that being said
<2> its not really a core function, its a bus controller architectural issue
<2> and cache controller
<1> well yeah
<1> what they should do is keep coherency on each chip
<1> but not each socket
<2> you know, sun already has 8-core on a chip with their T1 ultrasparc
<1> kinda a hybrid ****
<1> peerce, the t1 isn't much of a chip
<2> you HAVE to have coherency on each socket, or things get ****ed fast.
<1> it handles some things very well, and others horribly
<2> yes, I know.
<1> i dunno peerce
<2> we benchmarked it with Oracle
<1> but i'm _very_ excited about a 4 way server using only one socket
<1> as i'm sure, you are
<2> do they still only have 2 memory channels per chip?
<1> and a 35 watt x2 desktop cpu, pwn
<1> peerce yes, but it's ddr2 - 800
<3> skoal
<2> DDR2 isn't twice as fast overall as DDR, the latency is about the same
<1> latency is higher with ddr2
<2> yes, the bursts are faster
<2> but with higher latency, that greatly offsets the advantage of the bursts
<1> ddr 400, dual channel ~= 6.4GB/s
<1> ddr2 800, dual channel ~= 12.8 GB/s
<2> typically, the CPU L2 cache burst loads 1 cache row at a time
<1> i'm just talking controller bandwidth
<2> the cache rows are, I think, 32 bytes, so it only bursts 4 cycles. so you have [latency] + 4 bursts at 6.4 or 12.8. the latency is probably close to the same total time if not more
<1> and I correct in my ***umption that with current dual core chips, the ddr dual channel is sufficient?
<1> am*
<2> um, barely. you have two cores working the same memory interface as a single core. that puts a much heavier demand on the memory channels
<1> yes i know
<1> i'm saying are current chips bandwidth limited
<1> i don't think they are, given the fairly linear growth in performance
<2> and the simplistic cache coherency scheme used on these things is such that cache rows which modifed get discarded when they are referenced by another CPU, so OS overhead is quite high (cpu 1 discards, cpu2 loads, then cpu2 discards, cpu1 loads.
<2> it heavily depends on your workload.
<1> thus, doubling the bandwidth, should work out
<1> yeah ignore the cache coherency right now
<2> if you're doing scientific kind of work, where each CPU is just humming along running its own calculations with very little interaction, then things look great.
<2> but when you're doing **** like database, java services, networking, things start to **** more.
<1> true
<1> but with 12 GB/s to play with
<1> that's a lot dude
<2> thats a burst speed.
<1> it's twice the current burst speed
<1> at the cost of a slightly higher latency
<2> ok, 1/12th is, um, .08 nanoseconds? so 4 cycle burst at .08 nano is, um, .32 nano, then you need about 20 nano for the RAS/CAS latency before you get another 4 cycle burst from somewhere else.
<2> so the difference between .08 nano and .16 nano ain't so great.
<4> fixe dthe problem.
<4> ***ociative arrays in javascript is a definite misnomer.
<2> [and, I might have the cache width wrong, it might be a 8 cycle burst, and I'm pulling the RAS/CAS latency number out of my ***, I forget what it is, but its a LOT]
<1> that's way more into it, then i was prepared to go
<4> see http://www.comet.co.il/en/articles/hash/article.html
<4> needed to jimmy rig true ***ociative arrays
<1> yeah
<1> that's what i said
<2> lets see... 800Mhz DDR2 is *still* running on a 200Mhz clock, IIRC. and RAS is typically 5 clocks, and CAS is around 3 clocks. so 8 clocks at 200Mhz is, um. 5 * 8 == 40 nanoseconds.
<1> it needed declartion and setup
<4> i was ***uming javascript was capable
<4> that is not necessarily in PHP hence why i was confused
<1> i didn't think it could even do it
<1> i thought only java could
<4> i've done it.
<4> iv'e done this code before in php
<2> so those .08 nS vs .16nS bursts are suddendly dwarfed by 40nS overhead per burst.
<1> peerce stop my brain hurts
<4> just not javascript, trying to dynamically generate graphs based on cpu / interface utilization with only a browser and a backend php/net-snmp enabled host
<2> oh wait. it ain't .08/.16, its 1.25/2.5 (800 megaburst/sec vs 400megaburst/sec)
<2> anyways.
<2> so... athlon64 x2's, the toledo is the 'best' core now?
<5> my explorer is opening mpg files with quicktime when i click on it, i want open them with Windows Media Player, how can i change this can anyone help me ?
<2> MarcoPix; run quicktime, go into its options, somewhere is a dialog with filetypes, unclick mpg
<6> marco: right click on file you are trying to open, select open with, then choose program, then pick the prog you want to open it with and put a checkmark in always user the selected blah blah to open
<2> i'm bettign he means in INTERNET explorer, cuz i've seen that too.
<5> yes i mean internet exploer
<2> ah, its on browser -> mimetypes in preferences->quicktime
<7> Has anyone here successfully setup stmp and pop on a windows 2k3 server with the stuff built in?
<2> i run my email on unix
<8> the basic smtp daemon in windows server is kinda dumb
<8> even the w2k3 version
<7> got any decent simple alternatives
<8> for Windows?
<7> i used it once successfully for like a year but i changed servers and now i cant reconfigure it like I had it before for some reason
<7> and yes, windows platform
<8> no clue here
<8> I use Exchange
<7> is it easy to make exchange just send and recieve emails like it is with the windows stuff?
<9> Nothing is easy with Exchange.
<7> now why would that be
<7> isnt the number one thing when designing software is to think about the users and make things "user friendly"
<8> Exchange is overkill if all you want is an MTA
<8> WAY overkill
<8> there's other ****
<8> I just don't know what (for Windows)
<7> ok
<7> ill look around
<2> post.office used to be a popular email server for windows, never used it.
<2> I've never put any windows server outward facing on a internet connection
<10> Bush Said To Be 'Fixated' On Oval Office Rug...
<2> its easier for me to slap linux on a stable-but-old 400Mhz PC or whatever, and harden that, and run my email on there.
<11> oh hi MrHomo
<11> peerce, you still got rain up there?
<12> im having issues with installing office 2003, its telling me the maximum number of licences has been used but I only have 1 serial. Any ideas?
<11> we got m,ostly sun today and nuttin butt sun tomorrow
<2> sAMOa; nah, its over ... might be a few more showers, but nothing big
<2> tkd; how many times have you installed this one serial ?
<11> k
<12> peerce: a couple times but always after format/reinstall
<12> never on another computer
<2> what does the error message say to do? I've never seen a message that said 'maximum number of licenses has been used...' with an end user retail or oem version. is this a 'corporate' licensed version or something?
<2> if this is a retail boxed version, I'd call microsoft customer service. if its a OEM version, call the OEM who provided it.
<12> peerce: ok thanks for the info
<2> if its a corporate licensed (open, select, etc) then contact your network administrators, or your VAR.

<14> anyone here program C# and WMI ?>
<2> I've used a bit of WMI from WSH w/ jscript.
<2> !info WMI
<2> extensive help there
<2> haven't ever messed with C#
<13> wacky i fixed my windows update hell
<13> i wonder what freaking broke that
<13> had to use dial-a-fix to reregister the wu* dlls
<2> !infomod WMI = Windows Management Interface, powerful stuff used with WSH (Windows Scriptng Host).. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmisdk/wmi/wmi_start_page.asp
<2> [11:32] <2> extensive help there
<2> crap.
<15> If you yelled for 8 years, 7 months and 6 days you would have produced enough sound energy to heat one cup of coffee.
<15> If you farted consistently for 6 years and 9 months, enough gas is >produced to create the energy of an atomic bomb.

<14> i can't figure out what's wrong w/my code
