<0> hello
<0> I got a question.... multithreading seems very efficient for multi-processor systems. but say you have a multithreaded application using multiple kernel threads. how would this perform better than a single-threaded application on a single-processor system? because a single-processor system can only execute one instruction at a time anyways.
<1> it won't
<0> under no circumstances an application won't perform better?
<0> with multiple threads...?
<1> on uniprocessor, no; no that i know
<2> Multiple threads CAN improve performance on single processor machines
<2> Consider that if one thread is blocked on some external event another thread can still be doing some kind of processing
<0> Teckla, is that ***uming no context switch happens?
<0> after the block?
<0> oh wait
<2> I don't understand your question.
<0> nvm
<0> i'm an idiot
<2> Example: Thread #1 is doing some processing...then needs some data from the hard disk...and must block waiting for that data.
<2> The scheduler recognizes that thread #1 is blocked waiting for the hard disk and context switches to thread #2.
<2> Thread #2 can then do some work.
<2> With just a single thread, your entire process would be blocked waiting for the hard disk to serve the data.
<3> hi Teckla
<3> Any third year CS student would know that.
<0> heh
<2> Hi aedinius.
<3> What's up?
<2> You?
<3> Working on some literature homework.
<3> And wondering why my back hurts so much.
<2> You're getting old. ;)
<3> =(
<3> First words out of my mouth when my girlfriend is going ot be "back rub'
<3> Chances are she won't be feeling well either, so we'll probably end up taking a nap--oh my God, I am getting old
<3> My friend called her and I an "old married couple"
<2> Yep, taking naps is the first step of many. ;)
<4> Schnaps.
<3> Peach.
<3> Disgusting, I know.
<3> I've had peppermint before
<3> I didn't like it
<3> I couldn't stop vomiting afterwards
<5> aedinius, you don't like peppermint? i don't like spearamint much.
<3> I don't like peppermint Schnaps
<3> I like mint in other stuff, like gum
<5> oh. well peppermint schnaps is extremely strong in terms of peppermint.
<5> you'd not really supposed to gulp it down either. it's like equivalent to eating a bag of cough drops
<5> s/you'd/you're
<2> 22% of all laptops end up needing repairs. Wow
<5> so low? that's pretty good
<6> except dells, they just blow up
<5> i figured 100% of them end up needing repairs, eventually.
<5> my ibook needed repairs so I bought a new laptop instead.
<2> Both my Dell laptops have had numerous problems. Dell laptops have very serious quality problems
<5> none of the places that would repair it would actually gaurentee that the repairs would fix the problem.
<2> And that's why I'll never give Dell money again :)
<5> i was glad when one place i worked switched from Dells to Thinkpads. but thinkpads aren't really that reliable either (half the people in my department had the logic board replaced on their T43)
<2> We've had lots of ThinkPad problems where I work, though the two ThinkPads I've owned have been fine.
<7> my TP701C worked great
<2> Maybe because I treat my hardware well
<7> only problem is that it was a 75MHz 486DX4
<5> teckla, i totally lost that 1gb flash i showed you. the little chain-clip thing comes ondone too easily. i'm hopping it lost in my apartment and not out in the street.
<2> Nothing wrong with 75 MHz. That's plenty fast for all sorts of stuff
<7> and now I'm stuck on a dell latitude P3 500... which has the worst quality most infuriating keyboard and touchpad I have ever had the displeasure to use
<2> OrngeTide: Nooo! That ****s
<5> my HP 486DX2-66 worked like a champ for many years.
<5> Teckla, yea. i'll have to spend another $25 for a new one. ehhe
<7> unfortunately I was an idiot and sold it :(
<2> P3-500 is more than fast enough even for most modern day applications
<7> I wish I had that laptop back, it worked great
<7> Teckla: indeed
<2> Think of all the new computer sales lazy developers are responsible for.
<7> it doesn't game well at all of course, but the only game I play is from 2002 so it's not too bad
<8> if you only run a couple of apps:/
<2> Fatter and slower software requiring more and more hardware
<5> i miss my NECV20 8Mhz laptop (8088 clone). with 640x200 grayscale CGA display (backlit) and two 3.5" 1.44M floppy drives. (no harddrive).
<7> rip, more memory fixes that
<3> P3/500 ****s for porn.
<5> it died in a car accident.
<7> OrageTide: I have an NEC V20 chip I dug out of an old typewriter somewhere or other
<2> What? P3-500 is fine for pr0n. It's even plenty fast to playback video
<3> Nice
<6> lol
<7> I think I am going to soup up my XT BIOS hacking rig with it at some point
<3> Teckla: Yeah, like, one or two videos at a time
<2> aedinius: You need more?!?!
<5> but the video controller on it was pretty impressive. there were several fonts to choose from for text mode. and you could make it do bold letters instead of high-intensity colors (it was grayscalE) you could change what shade of gray each color mapped to. and you could do like italic font instead certain colors or underline, etc.
<3> =]
<3> My 900MHz laptop got stolen
<2> How many pr0n videos can you watch at a time anyway?!
<7> Teckla: as many as you have eyes, if you'
<7> re good enough
<5> if i were going to make a dumb terminal i would totally want it's video controller. it was like the fanciest textmode video controller i ever saw
<5> s/it's/its
<6> get a cell processor then, it can decode enough pr0n for you to watch
<3> I like Diet Dr. Pepper
<5> dr.pepper + red vines. .. hacker's lunch
<5> i'm allergic to most sugar substitutes
<3> That ****s
<3> Sugar makes me sick
<5> if i don't have sugar i get a little light headed. i'm addicted and go through withdrawl
<5> we have no diebetics in my family and everyone eats huge amouts of sugar.
<2> So many products in the U.S. also use corn syrup too which is not nearly as good as sugar.
<3> If I drink enough sugar (a large coke will do it) I tend to feel nauseous for a little while
<5> Teckla, yea. i found places like BevMo stock HFCS-free sodas.
<3> If I'm not areful I'll crash, get very lightheaded
<3> I nearly p***ed out once trying to talk to my boss at the time
<5> aedinius, then yea. you should drink diet soda
<3> I used ot hate diet
<5> i drink 1 or 2 sodas a day. or the caffeniene gets to me. (sometimes it's hard to fine caffeine-free. mostly i drink water.
<3> Now I drink it and it's like, hm, this isn't so bad.
<2> I drink diet soda
<2> Yay for artificial sweetners
<5> once you drink enough diet you burn out your tastebuds and can finally start to enjoy diet.
<6> It's weird when you've not "done any sugar" for a while, then drink some coke... It's like you go crazy/ get hyperactive
<3> Sugar never made me hyper
<5> kind of like how some people learn to like fermented fish or goat brains.
<3> I ate squid last night for dinner
<5> i love squid
<9> no you don't
<5> i eat squid like all the time.
<9> you let it rot in your freezer
<10> squid is kinda tasteless to me
<3> Yeah, we had sushi for dinner last night
<5> Pennyless, ehhe. you're the one who had to clean that fridge not me. so you probably don't like squid
<3> Well, we were at a buffet and it had cheap sushi
<5> Pennyless, oh. i was planning on eating it before the power turned off.
<5> Pennyless, that was actually my 3rd box of squid...
<3> Anyway, I only drink water, OJ and Cranberry, tea, and coffee.
<3> And recently I've had a few diet sodas
<5> the first box i cooked was a little tough. i needed to cook a fair bit to get practice:)
<5> aedinius, i love cranberry juice.
<3> I love it too.
<5> and grapefruit juice. i drink that way more then OJ
<3> I like the tartness
<7> I'm a big fan of pineapple
<5> OJ is usually too thick and sweet at most places.
<7> and dried papaya
<3> Ah.
<3> We get the OJ with the extra pulp
<5> CompHobby, i like pineapple-orange-banana juice. it's like a smoothie:)
<3> yeah!
<2> Here's a cool little computer: http://www.theinquirer.net/default.aspx?article=32703
<5> i usually just use pineapple for cooking rather than eating it plain. it's handy for making like sweet and sour dip and stuff
<5> pineapple juice and just keep basting a chicken with it while it cooks. YUM
<11> cooking with fruit juice is fruity
