Well, I'm no compiler geek, but from my work on scaling up C++ apps on Win32, the goal is to do as much work in your quanta before the O/S tears town the registers to handle the interrupt, &c. You're going to get switched every quanta anyway, but don't artificially do it, then you are "doing the theoretical maximum". This is what the few apps that scale up on Win32 to multiple CPUs (SQL Server is the only example I know of) do -- the term is "compute-bound", or "cpu-bound", rather than "memory-bound" or "io-bound". Mpeg encoding is another CPU-bound task.
Plus you would use at least a dual CPU so that 1 CPU basically gets I/O detail, and N-1 cpus do work.
Someone other poster can amplify this -- I'm basically parroting what the guys on the NT perf time (for whom I was a consultant) told me.
Why don't you just use the profiling tools to make your code run faster? The DirectX people do it all the time, Intel's tools will profile your code and show you what to fix. Just like programming for SMP, you should program properly for P4. I know it's a bitch, but that's life.
Code to fix == stalled pipelines. Surely there are general purpose math libraries optimized for P4 by now?
I miss the old Coleco handheld football games, where the "game" was just ten LEDs in a 5 x 2 grid. Seinfeld mentioned them in "The Toys" episode -- George loved them. Ran on a 9-volt battery. Man they rocked!
Also: my pre-Atari 2600 Pong machine: On/Off, Tennis/Squash/Pong!
Let's see, forgotten technology: my first student ID at UNC in 1989 had holes punched into it representing my SS#. By the next year they were handing out ones with magnetic stripes.
At my grocery store job in high school, when somebody handed us a credit card, we'd just walk over to this book and see if the number was one of the stolen ones (but only if we didn't "trust" what the person looked like -- i.e. a little old lady). This was because *no one* used credit cards at a grocery store -- very few people had ATM cards.
Manual "Toms" or "Lance" vending machines:: they didn't run on electricity. Purely mechanical devices. Sweet! Usually only found in rural areas.
The main freaky thing about looking at old pictures is seeing how all the companies' logos were completely different, but they all looked normal then!
I can't parallel park for shit. I need a space before the empty space I'm pulling in to, and even then, I rarely get it in there nice and tight. In a pinch I can pull it off.
I just hope when they say "we will enable Mozilla to run Oracle applications" they don't mean they are going to bloat it up with some non-standards compliant or stupid Java integration.
Be careful: they may throw money at it to Hijack it. I guess they can always fork.
Well except for the fact that when I say "R" my tongue is at the back of my throat and my lips are forward with the centers higher than the sides, and when I say "L" my tongue is at the top of my mouth and my lips are stretched out to the sides.
Yeah, it's offtopic. Just answer the question. Jeez, mod-happy much? I saw it the quote on Slashdot, no info on Google. Where else am I supposed to ask?
The more sober scientists tell you that robots can do more in space more cheaply than humans. However, they overlook the fact that sometime within the next million years, something is going to kill 90% of the life on this planet. Or maybe the next hundred million years. It *will* happen.
We have to get off this planet for that reason. Nothing else you spend the money on will be worth anything when that happens.
Oh, please, you are spouting flavor of the week propaganda, so pure! It must feel so good! To have moral clarity, none of that "everybody sucks" murkiness, to know right! All shall bow before me and goodness and mercy shall reign for all of my days!
Yeah, yeah, yeah. It used to be Nicaragua and those poor South American communists that gave the left fits. This Jew-hating fad of the left has flavor of the week written all over it, will the last jerkoff protesting it please shut out the lights.
So what you're saying is you throw away less information and it sounds better. In the long run, what's the difference between 100 gb and 500 gb? I prefer to spend a bit extra money because I know I have more data. It's like having a car with a lot of horsepower when the speedlimit is 55 mph.
I can hear the difference in cymbols. That's where most of the data is thrown away -- the bright, punchy cymbols.
Well, I oggify it for my laptop, and it sounds "okay" but I can hear the difference; mostly in the cymbols and, I dunno, some of the "punchiness" and "energy". Obviously for very high bitrate mp3s its harder, but the files are commensurately larger. Lossless each song is about 50 mb; I can fit about 11 CDs on each DVD-R.
All lossy music sounds like "cassette-quality" to me; I much prefer flac, since technology has allowed me to deal with 50 mb 3-minute songs like its no big deal.
I started downloading mp3s from usenet and irc in 1997; I never used napster.
I listen to lossless formats now (flac and shorten). I have 500 GB of hard drives and back up my music to DVD-R ($1 each for 4x media at Central Computer in Sunnyvale).
Fortunately most of the bands I like are jam bands and encourage swapping. I feel sorry for you poor folks thinking lossless music sounds good; I've moved on.
That's WinPE. It runs the GDI subsystem in VGA (non-accelerated mode only). There aren't many DLLs, so most graphical apps won't run: but Notepad will, with funny looking widgets.
It's not truly a command-line O/S: GDI32 still runs, with mouse and all: but it's a step towards that.
It's an outcrop of Microsoft's "server applicance" initaitives; you can pick and choose subpieces of windows. It's a wierd bird.
There's a solution called "Windows PE" (Windows Preexecution Environment), part of the "OEM Preinstallation Toolkit" specifically designed for the Dells and Compaqs of the world to preinstall the OS on the factory floor. I don't think it's publicly available. It is especially designed to boot from Readonly media, and it's supported.

I just know this stuff will be on "Tactical to Practical" ten years from now, like Velcro or GPS.
I can't parallel park for shit. I need a space before the empty space I'm pulling in to, and even then, I rarely get it in there nice and tight. In a pinch I can pull it off.
I kind of feel shame about it!
I for one welcome our new United States citizen overlords!
This is totally an advertisement. Bah.
First post, by the way, and yay Panthers.
I just hope when they say "we will enable Mozilla to run Oracle applications" they don't mean they are going to bloat it up with some non-standards compliant or stupid Java integration.

I for one welcome our freakishly strong forearmed child overlords.
Seriously -- rememeber the Chris Farley Skit: "My God, these Hideously Oversized and Freakishly Strong Children Will Surely Rise Up And Destroy Us?"
Well except for the fact that when I say "R" my tongue is at the back of my throat and my lips are forward with the centers higher than the sides,

They are the same in the throat.
Yeah, it's offtopic. Just answer the question. Jeez, mod-happy much? I saw it the quote on Slashdot, no info on Google. Where else am I supposed to ask?
I know I'm going to regret asking this, but what does "sillema sillema nika su" mean? It was a fortune on slashdot.
Google shows very few hits for "sillema".

Don't try to port a server application over to it -- the perf will be horrible.

So to "back-peddle" would mean Microsoft would be buying their internet service back from their customers. I think "back pedal" is correct.

Well shit I prefer a live concert in a room with good acoustics.
But between MP3 and Flac, I have a clear favorite.
The two are comprable.
Flac ripped with abcde.
BBS since 1986. MP3 since 1997, duh.
DARPANet? ... nah, i'm a newb -- internet only since 1993.
TB ... I back up my stuff with hard-drives
nothing wrong with that, what made you think I was trying to say I'm better?
Just saying I don't like lossy music...
Doh! I meant lossy, obviously.
