Arm DDT new features and enhancements

20.0

  • CUDA GDB is now shipped on AArch64.
  • Added Assembly debugging mode.
  • Added GDB 8.2 as an optional debugger.
  • Updated the MPICH3 auto-detection heuristics.
  • Fixed an issue where the program was unresponsive when debugging or profiling applications that expect user input from a pseudo terminal.
  • Added support for Ubuntu 18.04 on AArch64.
  • Added support for Ubuntu 18.04 on x86_64.
  • Upgraded CUDA GDB 10.1 to update 2.
  • Added support for Arm Compiler for Linux 19.3.
  • Added support for Arm Compiler for Linux 20.0.
  • Added support for Intel 19.x Compiler and MPI.
  • Updated the Support email address from allinea-support@arm.com to support-hpc-sw@arm.com.
  • Because of issues with the Data Address Watchpoint Register (DAWR) on POWER9, hardware watchpoints are not available from Linux kernel version 4.17. In this case, DDT falls back to software watchpoints which are significantly slower than using hardware watchpoints. More information can be found at https://github.com/torvalds/linux/blob/master/Documentation/powerpc/dawr-power9.rst.

20.0.1

  • Fixed an issue with two dimensional array slicing when using the Intel and GNU Fortran compilers.

Running DDT
===========

If you are using a supported desktop environment (KDE or Gnome), find the DDT icon in your Development > Programming menu.

To run DDT from the command line, type:

   {arm-forge-path}/bin/ddt

If {arm-forge-path}/bin is in your $PATH, type:

    ddt

You can optionally provide a program name as the first argument.

At startup, the Welcome page displays. From here you can choose to run a program, attach to an existing program, or open a core file.

To start debugging a program, click "Run". In the Run window, set the path to your program in the Application field, and click "Run" to start the program.

The program you choose runs using mpirun. If you have problems starting your program under DDT, ensure that it can run without DDT from the command line.

Running MAP
===========

If you are using a supported desktop environment (KDE or Gnome), find the MAP icon in your Development/Programming menu.

To run MAP from the command line, type:

   {arm-forge-path}/bin/map

If {arm-forge-path}/bin is in your $PATH, type:

    map

You can optionally provide a program name as the first argument.

At startup, the Welcome page displays.  From this page, you can profile a program, or load a profile from a previous run.

To start profiling a program, select "Profile". In the Run window, set the path to your program in the Application field, and click "Run" to start the program.

The program you choose runs using mpirun.  If you have problems starting your program under MAP, ensure that it can run without MAP from the command line.
