Viewing CAF Programs (Classic UI Only)

TotalView : TotalView User Guide : PART III Parallel Debugging : Setting Up Parallel Sessions : Non-MPI Program Setup : CoArray Fortran (CAF) Programs : Viewing CAF Programs (Classic UI Only)

For a CAF program, the process id in the TotalView Process window shows the CAF image id. TotalView shows the correct dimensions and co-dimensions of arrays and the co-dimensions of scalars.

When diving on a CAF array or scalar, TotalView shows the data local to the current image. Diving across processes shows the entire distributed array.

If you use the array viewer, statistics, and visualizer commands from the Tools menu when viewing a CAF array across processes, the commands treat the co-array dimensions much like standard array dimensions.
