Hyperthreading is sweet

  1. Hi All,

    Since midsummer last year I am running a 2.8MGHz P4 with all the works, using hyperthreading, of course. I am rather pleased with it. I couldn't get the 3.2GHz last year but it is the fastest rig I ever had.

    I have a question though about the CPU usage as displayed by the "Windows Task Manager" under the "Performance " tab. I never seem to be able to get this usage figure much above 55%. Is this also your experience?

    I used to run a multiprocessor system some years back and I found that it required quite a bit of planning in assigning different tasks to each processor to get things well loaded. This is rather difficult for a workstation that you write programs for. I once started to write C++ multithreaded code. This worked OK but found it much too impractical for me as it required another dimension of complexity. You had to constantly figure out how to segment your algorithms into a useful cooperative scheme in order to get any real benifit from this. So I'm back to single processors but the "hyperthreading" still gets you less or more in the same bind. If you figure out the right way to load it, OK. But this is highly dependent from one job to the other.

    Do I get this right?

    Brother LS,

    Look at it this way, having my dual Xeons pegged at 90% for about 85% of the day is par for me. If the market even gets a little action, I get pegged at 100%. That is on a machine that would run rings around any machine mentioned here.

    Further, I am doing about 1/20 of the amount of analysis I need to do in realtime.

    That is what is so "funny," or better said, what is so sad.

  7. I think you are much better off pasting in pictures of your Corvette down in "Chit-Chat". Up here in Hardware-Land, I think that Nitro has you by the balls!

    :D

  8. Give me any amount of CPU power, and I can peg it at 100%.

    If you cant, it only means you dont know how to fully use
    your cpu power, or dont have the need to.


    peace

  10. PM me.

    where did you get such a bargain?

    also, do you think that the Centrino thin weight laptops can perform similarly?

    I'm interested in losing weight and longer battery life.
