I am trying to run my first MPI project and have a problem with credentials. Long story short, I have entered credentials and then realised I didn`t actually registered. Now, every time I`m starting the project prompt says: Credentials for <username> rejected connecting to <PCname>.
I wonder, how do I change the credentials I`ve entered and should have I registered with some specific name and password depending on PC name, windows username, etc. ?
Just double checking -- you obviously work with Windows. I'd suggest to look for starters at this post (you can search inside for credentials)
I hope you registered your credentials with
> mpiexec -register
you can Type "mpiexec -remove" to remove the registered username/password
Try not specifying username when running mpiexec -register. Just password for your current user
