Re: [HTCondor-users] comments on installing Personal Condor

[Ian Cottam <Ian.Cottam@xxxxxxxxxxxxxxxx>]

I thought I would just add something I thought was quite simple and pleasing, regarding the training course I am working on....

I have set up a Windows 10/64 laptop with Personal Condor.
On the same laptop I'm running Ubuntu 18 under Microsoft's pre-release of WSL2; it too has a Personal Condor install. (BTW, Microsoft's normal release of WSL2 to all is due sometime between Easter and summer this year.)
I set up FLOCK_TO/FLOCK_FROM relations between the two personal pools.
Submitting Windows based jobs from the Linux pool works perfectly, and shows a very nice example of how flocking works between pools of different architectures.

The other direction doesn't seem to work (i.e. trying to submit a Linux job to the Windows pool).
I think this is because the Linux Personal Condor is running on 127.0.0.1. (The Windows pool gets a 10.186.???.??? IP address.)

I'm happy with the one direction working, so not really requesting help or advice on this: just reporting.

Subject: [HTCondor-users] comments on installing Personal Condor

    Hi all,
    
    Just some comments on installing Personal Condor...
    
    I'll be helping with some Condor training towards the end of next month. It's likely that attendees will use Personal Condor. To that end, I have done installs of Personal Condor on macOS, Linux (Ubuntu 18) and Windows 10/64. Here are some observations from someone who hasn't done this for many years.
    
    1. Linux and macOS were extremely simple: in part this is due to the option --make-personal-condor.
    I found it in the manual under condor_annex, which a newbie might not find.
    The Linux version I installed on my Windows 10 laptop under WSL2 (Windows Subsystem Linux 2 pre-release), where it works fine. I have both Linux and Windows Personal Condors on the same machine. (In fact the hardware is a MacBook Air, so I could put the macOS version on it too.)
    
    2. Under Windows 10/64, with the msi file, there is no equivalent to --make-personal-condor. I knew what answers to give the setup wizard, but again a newbie might not. It would be good if the first step was "Do you just want a Personal Condor setting up?".
    About a decade ago I remember commenting that it was ironic that the easiest install of Condor was under Windows (when it is developed under Linux), perhaps not the case anymore - especially for Personal Condor).
    
    3. It would be nice if dynamic slots were the default. Any reason why not, apart from history?
    
    Keep up the great work!
    -Ian
