I have used 20.7 since it was released. I tried to update 20.11, and it seemed to work until I put -stdpar
in the command-line. I think I have traced the problem to one of the rcfile(s) which refers to 20.7. But I don’t understand how to fix it. Help please, particularly with regard to not repeating the problem when I install 21.1!

Hi Malcom,
The compiler versions are installed in separate directories and the configuration files (rcfiles) wouldn’t point to previous releases.
Can you post an example of the issue you’re seeing? This may help in determining the issue.
Thanks,
Mat
Good morning Mat. Seeing your name made it feel like meeting an old friend!
It appears that I am using 20.7, while believing I was running 20.11! I am displaying the results ofaa few relevant(!) commands:

As you can see, 20.11 is installed, but apparently not ‘activated’! What should I do to be using 20.11?

Hi Malcom,
What’s your PATH environment variable set to? (i.e. post the output from the command “echo $PATH”).
My guess is you still have your PATH pointing to the 20.7 install, or at least have it listed before the local directory (“.”). The OS uses the first instance of a binary it finds with precedence to directories listed earlier in PATH. So if you have “/opt/nvidia/hpc_sdk/Linux_x86_64/20.7/compilers/bin” listed before “.” or “/opt/nvidia/hpc_sdk/Linux_x86_64/20.11/compilers/bin” , the 20.7 nvfortran binary will be used.

Mat, you were correct! That was the problem.
Thanks.
