yeah you'd need more bandwidth than that for 8
cores definitely |
06:16.43 |
Maloeran |
It's ridiculous, I think my old Pentium ( 1995
) has that much bandwidth to main memory |
06:18.52 |
Maloeran |
Oops it wasn't double-rate though. Okay, it
has half that bandwidth |
06:19.40 |
louipc |
my current system does that anyways and it's 6
yrs old |

I'm thinking I'll wait AMD's Barcelone chips
next, far superior memory archtiecture |

architecture, rather |
06:29.44 |
louipc |
oh they're going 128-bit already? |
06:30.07 |
Maloeran |
Eh? No, there's no way we'll ever exceed a 64
bits addressing space :) |
06:30.36 |
Maloeran |
I mean it scales properly with the amount of
cores, distinct memory banks and bus |
06:30.40 |

ok I just read something in a news article

no way we'll ever exceed a 64b addressing
space? hmmmm, kinda like 640k should be enough for anyone?
:D |
15:59.02 |
Maloeran |
18 million tetrabytes? There's a physical
problem, we need enough atoms to contain the information |
15:59.34 |
``Erik |
18m? my computation says that unsigned would
be 16 exabytes... |

just wait 6 months for the ram to appear on

you'd still have 4080 2^64 spaces in one avagadro's

"[...] desire to run very fast would preclude
distributed/network processing ... no?" What have you guys done
for managers to think that distributed processing == slow?
:) |
17:58.33 |
``Erik |
where'd you read that? |
18:01.50 |
Maloeran |
Mark's reply about distributed processing for
their fire modelling |
18:02.43 |
``Erik |
hm, I can name two projects here that you've
heard about that are distributed, extremely slow, and virtually
non-scalable. |
18:03.13 |
Maloeran |
Eheh, I thought so |
18:03.53 |
``Erik |
imho; both use tiny work quanta and poor
aggregation techniques. |
18:04.14 |
``Erik |
they're "chatty", too |
18:05.33 |
Maloeran |
I'm just amused by the assumption that
distributed processing would make things slower. Why would we
distribute processing if it weren't for speed? :) |
18:06.16 |
``Erik |
distributed processing induces overhead, if
you don't keep it in mind, you actually do get software that runs
slower :) |
18:06.27 |
``Erik |
which is why the production one is usually run
serially |
