VTune Profiler does not support 32-bit operating systems. However, you can use VTune Profiler to profile 32-bit applications on 64-bit operating systems (cross-mode). Please find system requirements doc for more information
Well it does and it doesn't. I was trying to use Vtune on a 64 bit Windows PC to profile a remote Linux 32 bit target. The documentation suggests this is possible (https://software.intel.com/en-us/vtune-help-linux-system-setup-for-remote-analysis) saying there should be a "<install-dir>/target/linux/vtune_profiler_target_x86.tgz - provides all VTune Profiler collectors for x86 systems" in the target directory but there isn't.
I went back a few versions to Vtune Amplifier 2019 & the tarballs are present & I was able to successfully profile the 32 bit system but as it stands it seems 32 bit remote profiling support was removed from the latest versions of Vtune but the documentation was not updated to acknowledge this.
Indeed, the 32bit OS support is deprecated.
