When debugging Cell programs, be aware of the two different architectures, as they have different behaviors. The PPU is a standard IBM Linux PowerPC. Interact with programs running on the PPU in exactly the same way as with standard Linux PowerPC programs.
Since it is typical to run multiple Cell machines together, each PPU process running the same program is placed in one share group. If more than one executable is being run, each set of identical programs is placed in its own share group. All of these share groups are contained within one control group. The way in which TotalView groups processes and threads is identical to how it groups them on all other architectures.
