Hello Josema,

Python supplied with Rocket z/OS Miniconda is just an IBM Python that is repackaged to Conda package format. Miniconda installer version 2.0.8 (miniconda-zos-2.0.8-2024-04-12.run) contains IBM Python 3.11.5, that allows to offload Python workload to the zIIP specialty processor.

To take advantage of the zIIP, APF authorization must be set for the shared library "libpyzutil" after IBM Python installation.

To set APF authorization for the required shared library, you should run the command:

extattr +a <path_to_python_install>/lib/python3.11/lib-dynload/libpyzutil.cpython-311.so

To verify that APF authorization is correctly set, you can run the command:

extattr <path_to_python_install>/lib/python3.11/lib-dynload/libpyzutil.cpython-311.so

Regards,

Thanks @Vladimir Kudriakov 

Indeed, the python version is the one you indicate:

P083598:/u/P083598:>python3 -V 
Python 3.11.5                  

And (now) is APF:

P083598:/u/P083598:>extattr /usr/lpp/ported/lib/python3.11/lib-dynload/libpyzutil.cpython-311.so                                                                
/usr/lpp/ported/lib/python3.11/lib-dynload/libpyzutil.cpython-311.so            
APF authorized = YES                                                            
Program controlled = NO                                                         
Shared address space = YES                                                      
Shared library = NO
