WRF-EMS Time Trials Are In!

Updated my weather model computer.  Installed the latest Ubuntu last night (Maverick Meerkat Lucid Lynx).  The Phenom II X6 1055T CPU arrived today from the happy brown truck, and that has been swapped in.  The old CPU was a Phenom X4 9950 BE.

Here is the benchmark I ran last summer.  Using 9.04 version of the 32-bit flavor of Ubuntu.  27 minutes 39 seconds.

The benchmark I ran after installing 10.04 of Ubuntu.  Did this earlier this morning. Now with 8 GB memory and the 64 bit flavor.  21 minutes 20 seconds.

Finally, the benchmark after swapping in the new CPU.  17 minutes 24 seconds.

The other thing I was curious about was energy usage.  I hooked up my Kill A Watt before and after the CPU swap, and came up with these numbers.

        Phenom X4 9950    Phenom II X6 1055T


Idle 78 watts 67 watts


Load 165 watts 130 watts

More cores, but less power usage.  Gotta like that.  That is a reflection of moving from 65nm to 45 nm SOI.

Next move… strongly considering a cluster of these.  Probably a few months down the road, though.

RT @badbanana: Seriously. Once you learn how it reaches your dinner plate, you’ll never want to eat human flesh again.

36 holes of disc golf. Have I told you of the importance of a floating disc?

10.04

Upgrading my Ubuntu install from 9.10 to 10.04 as I type.  Apparently it will have a very pretty UI.  Also the end of the brown theme on the default desktop.  I’ll miss brown.

I am guessing the pretty UI is needed to cover up bloat.  The install process downloaded 722 MB worth of additional bloat.  I like bloat.  Bloat is very American, like a KFC double down.

This is where I attempt to impress you that I have been using Linux since I installed Slackware 1.00 during the winter of 93-94 on a 386 computer I purchased specifically for it.  This is where you think I am utterly pathetic.  Then this is where Hercule Poirot boasts, “Because that rich woman was not wearing her charm bracelet, it is with order and method I deduce, you could not have been sitting at that church pew!”.

I concede.
