O openMosix n�o migra threads, visto que elas compartilham a mesma regi�o de mem�ria (shared memory), prendendo assim este processo nesta m�quina.
Foi mal... � que o openMosix migra as greenthreads do Java, mas que realmente n�o tem nada haver com threads de sistema.
Depois de encontrares este encoder coloca o OpenMosix que ele deve distribuir tudo direitinho.
Ai vai a solu��o

*bladeenc*
cdparanoia -B
for n in `ls *.wav`;
do bladeenc -quit -quiet $n -256 -copy -crc &
done;
Ai vai outras....
* *FLAC* is a lossless audio encoder. http://flac.sourceforge.net/ * *Grip* is a gtk-based cd-player and cd-ripper. You can rip on one node with /cdparanoia/ and encode on the rest of the nodes with *oggenc* http://www.vorbis.com/ *
*LAME* Ain't an MP3 Encoder http://lame.sourceforge.net/
o Note: Lame and other applications often get compiled for a specific platform, as in march=pentium4 because they initially only run on 1 node. If later other nodes get attached with a different processor, such as a Pentium3, this can cause crashes, however not related to openMosix
* *mpg321(mpg123)* migrates well when playing and encoding wave files. * *FreeJ* claims to support this for creating videolivesets. Untested. http://www.freej.org * *LiVES* Linux (i) Video Editing Studio using mplayer and mencoder. Migrates very nicely due to its use of several sub-programs to do the actual audio and video editing.
