mpiexec problem with parallel jobs

[=?GB2312?Q?=B3=C2=BD=F8=C6=BD?=]

  hi all:
    I have a parallel job needed to run ,I use openpbs,mpich2 and=
 mpiexec-0.80 to build my env. here list my problems:
1:I must startup mpd daemon first for mpiexec ,but the mpd daemon=
 are out of openpbs's monitor !
2:when I use "mpiexec" in a pbs scirpt to run a parallel job ,it=
 run on every node individually ,this is to say it doesn't run=
 like mpich2'mpiexec.
