CPU2017 Flag Description
IBM Corporation IBM Power E1080 (3.55 - 4 GHz, 120 core, AIX)

Compilers: IBM Open XL C/C++ for AIX 17.1.0

Compilers: IBM Open XL Fortran for AIX 17.1.0

Libraries: tcmalloc version 2.7.1 + IBM AIX enablement patch Available for download at : https://github.com/gilamn5tr/gperftools/archive/refs/heads/aix-enablement-upstream.zip

Tcmalloc library has been built with IBM XL 16.1.0 with the compiler flags -O3 -qmaxmem=-1, where -qmaxmem=-1 permits each optimization to take as much memory as it needs without checking for limits

Operating systems: AIX V7.2 Technology Level 5, Service Pack 3 running on Power10 in Power9 compatibility mode
