Q&A

1. What's the preferable way access/sync files and directories (e.g. from LUMI home directory) on a local computer? I've used 'rclone mount' so far, is it OK?

   • rclone mount? That is for accessing object storage?

     There is more later in the presentation. For small transfers you're OK with rsync over ssh or sftp. I personally use rsync but only on selected subdirectories.

     For large transfers I would recommend to transfer from LUMI to object storage and then from object storage to your home machine. The difference is that those use multistream protocols that can get a much higher combined bandwidth than you can with a single stream tool such as rsync or sftp.

   Thanks for the answer. I was referring to my user home directory, which mostly contains just some source code or software config files. So I used rclone (which is built on rsync but preferred by my university) to simply mount that directory on my local computer, which is apparently fine.
