Arm Forge and Performance Reports – 18.1.1 available

Our 18.1.1 release for Arm Forge and Arm Performance Reports is now available and offers some enhancements to improve the behaviour of Arm DDT debugger and the Arm MAP profiler across all architectures.

A notable new feature of the Arm DDT debugger in this release is the addition of CUDA 9 support and reduced memory overhead when using memory debugging.

Among the various enhancements for Arm MAP and Arm Performance Reports, we’ve been able to reduce the overhead of both products when profiling executables or shared libraries that do not include .eh_frame_header sections. We’ve also added support for numactl across all products.

See below for a full list of enhancements and helpful bug fixes in each product.

Arm Forge

Arm DDT

New features and enhancements

• Updated our licensing model to include a new "Arm Allinea Studio" licence type.
• Added support of numactl for Arm DDT.
• Added a sanitizer plugin to Arm DDT, causing Arm DDT to stop the execution of a program if an address, memory or thread sanitizer error is detected.
• Added support of CUDA 9 to Arm DDT.
• Reduced Arm DDT memory overhead when using memory debugging.

Bug fixes

• Fixed a visualization glitch in the Windows client graphical interface.
• Fixed a bug causing Arm DDT to crash when using the commands "step", "next" and "cont" in raw commands.
• Fixed a bug which caused the multi-dimensional array viewer to display erroneous information.
• Fixed a bug causing Arm DDT to hang when attaching to MPI processes on an oversubscribed AArch64 machine.
• Fixed a bug causing Arm DDT to print incorrect values when slicing Fortran arrays.
• Fixed a bug causing Arm DDT to display an incorrect pointer stack on AArch64.
• Fixed a bug causing OpenMPI system threads to be detected and displayed as such in the Parallel Stack View on AArch64.
• Fixed a visualization glitch in the user guide.

Arm MAP

New features and enhancements

• Updated our licensing model to include a new "Arm Allinea Studio" licence type.
• Improved Arm MAP’s error messages when a specific CPU metric is not available on the system.
• Removed CPU and GPU metrics from profiles generated on platforms where the metrics are not supported.
• Significantly reduced the overhead of Arm MAP when profiling executables or shared libraries that do not include .eh_frame_header sections.
• Added support of numactl for Arm MAP.
• Added an option to enable and disable metrics.
• Improved the documentation related to custom metrics.
• Added a message when a job is terminated because of the "--stop-after" option.
• Using the "ALLINEA_NOTES" environment variable which enables users to add notes to the Arm MAP XML output files.

Bug fixes

• Fixed a visualization glitch in the Windows client graphical interface.
• Fixed a bug causing Arm MAP to report a tcmalloc error when trying to profile a dynamic executable compiled in an Intel programming environment on Cray systems.
• Fixed a visualization glitch in the user guide.
