Starting MPI Issues
* 
In many cases, you can bypass the procedure described in this section. For more information, see “Debugging MPI Programs”.
If you can’t successfully start MemoryScape on MPI programs, check the following:
*Can you successfully start MPICH programs without MemoryScape?
The MPICH code contains some useful scripts that help verify that you can start remote processes on all computers in your computers file. (See tstmachines in mpich/util.)
*Does the TotalView Server (tvdsvr) fail to start?
Remember that MemoryScape uses ssh -x to start the server, and that this command doesn’t pass your current environment to remotely started processes.
*Under some circumstances, MPICH kills MemoryScape with the SIGINT signal. You can see this behavior when you use the Kill command as the first step in restarting an MPICH job.
