Please refer to the supported platforms pages on the Arm Developer website:

https://developer.arm.com/products/software-development-tools/hpc/arm-performance-reports/arm-performance-reports-platforms

Installation instructions
=========================

Run the graphical "installer" or the text-only "textinstall.sh" from the download tarball.

You may choose to install just for you or for all users on your system.

If you are installing on a cluster, please make sure the package is available at the same path on every machine.

Full installation instructions are available in the Arm Performance Reports user guide, available on the Arm Developer website:

https://developer.arm.com/docs/101137/latest/installation

Uninstalling Arm Performance Reports
====================================

To uninstall Arm Performance Reports, remove the installation directory from your system:

rm -r <installation-dir>

Licences
========

If you do not have a licence file you will need to obtain one from Arm. Evaluation licences may be obtained from the Arm website:

https://www.arm.com/products/development-tools/hpc-tools/get-software

Full licences may be obtained by emailing HPCToolsSales@arm.com. Licence files should be stored in a directory called licences below the installation directory. For a default (root) installation, that directory would be:

   /opt/arm/reports/licences

and for a user-only installation it would be:

   ${HOME}/arm/reports/licences

Running Arm Performance Reports
===============================

To run Arm Performance Reports, add 'perf-report' in front of your existing mpiexec or aprun command-line, e.g.:

     {arm-reports-path}/bin/perf-report mpiexec -n 4 examples/wave_c

If {arm-reports-path}/bin is in your $PATH, just 'perf-report' will do.

Your chosen program will be run just as before and two report files, one .txt and one .html will be created in the current directory on completion. If you have problems starting your program under Performance Reports, first ensure it can run without Performance Reports with no errors.

You can use the --output/-o argument to specify a single output file name.

See perf-report --help or the user guide for more information.

Examples
========

Example code can be found in the installation directory:

   <INSTALL_DIR>/examples

Copy the example code to a writeable directory and run the examples using the makefiles provided.
