    There's also the question of counting of conting flops which they comment on as being conservative, at 1 Flop per instruction without regard for number of operations performed. In comparisons it's fair as all machines are measured by the same amount, but it's not the same as Flops as counted in other system. ie. PS3 may be well over a Petaflop by now... :p

    PC 152 TFLOPS
    PS3 598 TFLOPS
    Total: 851 :)

    This lays it out quite well

    Yeah, I don't know what sort of commitment they're expecting from the non-dedicated Folder. Depending on % of missed W.U. they may need to start working on background functionality sooner :twisted: If they can get Blu-ray playback & Folding (2-4 spu split), = a 33% reduction in Folding for 2-4 hrs, they could extend the deadlines a day, maybe half a day.

    Although it looks like you can surf

    Correct? (I can't check...)

    And this is nice
    So, no numbers (on the map?) but quicker than the Folding@Home stats page , which is about every hour at the moment.

    What about games then, done any of that? :lol:

    Hehe. You're serious about folding..

    Not sure if it's a sign of things to come but my apartement feels warmer with PS3 running all day long fiolding. And summer's not even here yet blaaagh..
    Peace.

    Not sure why they're being conservative. I mean, how can you be conservative when Flop ought to have a scientific definition? It's one atomic operation performed on a float - an ADD or a MUL or what have you. Where an instruction uses more than one of these to be calculated, even if executed in a single cycle by clever hardware, it should still count for as many atomic operations needed to perform that instruction.

    I kinda thought that these parts covered that

    Can you imagine what some of the other sites would be like already...

    ... that's (atleast 4x) 2.46 PFLOPS -right now-

    That's something I'd rather not think about any more :evil::runaway:

    Is this a scientific definition?
    Because that means nothing to me.:oops:

    Then there's always

    as a last resort? :grin:

    No. those are caluculations you want to perform. They are executed through several atomic functions. The current flop measure is kinda like measuring the distance of a road by lengths of string. Different strings have different lengths, but you count mile long bits of string the same as metre long bits of string to keep the numbers a comfortable size. Proper measurements would place the length in pieces of string as the smallest measure of string, perhaps 1m. That'll give huge figures for lengths. Instead of roads being 100 pieces of string of assorted lengths, they'll be 10,000 pieces of uniformly sized string, and actually mean something.

    The problem with suddenly massive Flop figures would (or at least ought to) be negated by the fact all figures would increase accordingly. Plus the scientific community shouldn't choose arbitary standards to appease forumites!

    Ugh... I think I understand. No sleep last night :sleeping:

    I was thinking if you had, say 20m long pieces of string (any less valid than the...?) 1m long pieces of string, that ummm, the people who care about measuring other peoples string (err... peer review...? I feel like I'm trying to hard:sleeping:) would look at all the string on the road .. and say 'screw it. look, there's a pub' :yes:

    LOL I bet I'm gonna look at this post tomorrow and go 'wtf:?:' :sleeping:

    Well yeah :wink4:

    27260 PS3s achieving 668 TFLOPs now (Total 922 TFLOPs).

    EDIT: Oops, dropped a little bto 659 TFLOPs (Total 913 TFLOPs). Perhaps people want to play game over the weekend :)

    Now 686 TFLOPs (Total 941 TFLOPs). Go ! Go ! Go !

    I actually remembered MS & Sony both saying they were going to do just this back in 2005. So now Sony has done it a few months after the PS3 launch, what happened to MS doing it on the 360? Was there an unseen technical issue?

    Unseen technical issue = red rings of death?

    Since the 360 draws less watts than the PS3 I doubt it.

    I'm afraid that MS just decided that it's not that important & gave up on the idea, which would suck big time for lots of reasons.

    Hint: The answer starts with n and ends with othing

    What does the red ring of death have to do with watts drawn?

    Heat & failure rates. But since you were being facetious, so was I.

    BTW, anyone know why the nVidia can't get their GPU's to do F@H?

    EDIT: n/m here it is:

    How hot something gerts really has no direct correlation to how muc hwattage it draws.

    Obviously the hotness level depends on the mass of the object amount of cooling received and thermal resistance and loads of other stuff I don't really have a firm grasp of.

    Quick and dirty example..
    If you take a small piece of wire resistor and run a bit of current through it it'll likely get really hot. Even if it's just a few watrts. If you wrap it up in cotton the bundle might get so hot it catches fire.

    So even though PS3 draws more watts than 360 it need not neccessarily run hotter. Or it might. One has to check to be sure.
    Peace.

    How are the mapping the locations of the PS3 clients?

    By IP or by the personal info. we enter to get PSN accounts?

    I don't recall MS ever suggesting the use of XB360 as a DC client. Sony on the other hand have been on and on about network computing. Supposedly Folding isn't the only choice PS3 owners will get with DC.

    As for the peak numbers, I wonder when PS3 owners will settle down to the 'only 10% active at any time' that we see with PCs and Linux? These PS3 owners aren't going to be running Folding forever, and eventually the TFlop will drop, like PC's is 1/10th of it's peak maximum. I'm sure we'll hit the Petaflop, and there'll be a huge press release shindig, but then performance might drop even below PCs and the actually contribution, though note-worthy, won't be the spectacle we're seeing now. Unless the PS3 Folders have a different mindset.

    Yeah, that's what I figured too ...unless there is a transparent way to run F@H on PS3 without user involvement (set and forget).
