Cray Linux Environment (CLE)
CLE applications are similar to those on Cray XT Catamount. The primary difference is that CLE applications are launched using aprun rather than yod.
Most — perhaps all — programs are launched using a batch queueing system such as PBS, Moab, and so on. While this is independent from TotalView, you will need to do queue up for an interactive session. For example:
qsub -I -sz=size
Here is an example of how you would start a CLE debugging session:
totalview aprun -a -n4 a.out
TotalView is not able to stop your program before it calls MPI_Init(). While this is typically at the beginning of main(), the actual location depends on how you’ve written the program. This means that if you set a breakpoint before the MPI_Init() call, TotalView ignores it because the statement upon which you set the breakpoint will have already executed.
