    Paul:
    
    Do you know anything about the LAM mpirun '-ton' tracing flag?  It sounds like
    jobs started with it won't restart correctly.

    Dear Sir or Madam:
    
         I try to checkpoint and restart mpi programs with blcr in LAM environment !
    
         I want to checkpoint some mpi programs which are launched with the
         '-ton'  so that I can get the trace files that LAM has
         produced. After I restart the context file,  the processes such as
         mpirun, cr_restart and mpi program, have been restarted, but they
         don't continue to run. when I checkpoint the mpi programs
         without the '-ton', everything is ok !  It is so weird ! 
        can blcr work well with the "mpirun -ton ....." ?
        Thanks very much!
    
       the first commands are as followings:(with 'ton') 
           mpirun C -ton  ./ring
          cr_checkpoint   pid of mpirun
          cr_restart  context.XXXX            (restart failed, the processed have been restarted but don't continue)
    
       the second comands are as following:(without  '-ton')
            mpirun C ./ring
           cr_checkpoint   pid of mpirun
           cr_restart  context.XXXX              (restart is ok)
    
      
       redhat 9 
       the version of blcr is 0.2.2.3b8
       the lam version is 7.0.4
                                                           deward
