Topic 188738

Hello,

I was wondering what the computations are about and what the orientation of the spinning star ball is all about.

Another thing; this LIGO work program is sucking up a lot of my computer's processing power.

I have a Pentium 2 350 mhz processor and 384 MB of ram.

Hi Mike !

From the signatures of your computer in your profile, you seem to be running EAH in a Linux/Wine environment. So do I.

If this is really the case, try using 'nice'. I started boinc this way :

(kami)roger:/ligo/Program Files/BOINC
$ nice -n 19 wine boinc_cli.exe 2>&1 | tee -a boinc-runlog

When boinc is 'niced', it will eat up all processing cycles left over by other programs and the CPU will be 100% busy. But boinc runs as a low-priority task thas should'nt noticeably slow down other applications.

Otherwise, you still can modify your preferences to prevent 'Doing work while the computer is in use'. And have boinc running in the background, I believe you can download a script to do this.

Thanks rg, What about the

Thanks rg,
What about the details concerning the animated spinning star ball??
What kind of LIGO data is being calculated?

Nevermind, I found the answer

Nevermind,
I found the answer in another post:
E@H uses fast fourier transforms (FFT) to look for gravitational waves.

Are there any interesting animations showing FFT’s being processed?
