Device (not emulator) support

CUDA function inlining support

CUDA memcheck functionality support

Linux threads and GPU device threads visibility

Representation of hierarchical memory with type qualification

Display and navigation using logical thread and block coordinates and hardware coordinates

Breakpoints and stepping code running on the device

Interoperability with MPI for use in accelerated clusters

A 2D array viewer enables viewing a multi-dimensional array in a two-dimensional grid, allowing for setting the slice and stride within the dimensions to limit the amount of data in view. It includes a mechanism for controlling the numerical precision of the data displayed.

C++View is an extension of TotalView’s type transformation facility, to allow formatting functions to be written in the user’s target code and preferred language rather than in TCL code in the debugger.

The parallel backtrace feature provides a single view to the state of every process/thread in a parallel job. It displays the host, status, process ID, rank and the line of code being executed.

TVScript support has been expanded to include the Cray XT, Blue Gene/L and Blue Gene/P platforms.

The Data Window supports display of very long C++ expressions.
