E Compiler notes

For a list of supported compiler versions, refer to section B .

E.1 AMD OpenCL compiler

Not supported by Arm Performance Reports.

E.2 Berkeley UPC compiler

Not supported by Arm Performance Reports.

E.3 Cray compiler environment

The Cray UPC compiler is not supported by Arm Performance Reports.


The -foptimize-sibling-calls optimization (used in -O2, -O3 and -Os) interfere with the detection of some OpenMP regions.

If your code is affected with this issue add -fno-optimize-sibling-calls to disable it and allow Arm Performance Reports to detect all the OpenMP regions in your code.

Debugging Python code compiled with GNU versions greater than 7.4.0 on Ubuntu 18.04 is currently unavailable. This is to be resolved in a future version of the product.


Arm Performance Reports does not support this.

E.5 Intel compilers

Refer to section B for a list of supported versions.

E.6 Portland Group compilers

Arm Performance Reports has been tested with Portland Tools 14 onwards.
