<P><FONT SIZE=2 FACE="Arial">I want to start multipel rings as one user on a linux cluster to submit more than one job at a time. Therefore I use mpdboot and mpdexec:</FONT></P>

<P><SPAN LANG="de"><FONT SIZE=2 FACE="Arial">I tried to set MPD_CON_EXT before starting the mpdboot and this allows me to start multiple mpds on the host where the ring starts, but not on the other hosts of the ring.</FONT></SPAN></P>
<P><SPAN LANG="de"><FONT SIZE=2 FACE="Arial">I also tried to use -1 option with mpdboot, but this did not work either.</FONT></SPAN>
