Hi Robert,

For workstations, I like openSUSE very much and I'd probably not give it
away for anything else (including Ubuntu). Although this is probably
also because I know it so well now that I can do much faster
troubleshooting than in others.

I have to say though that during my postdoc, I was not happy with Debian
.....

At the end of the day, for a workstation I believe between
openSUSE/Ubuntu/RedHat is a matter of taste ... Probably each of them
will work pretty well .... And in the end you should also remember that
the distribution is just the packaging of a Linux system .... Just pay
attention at installation defaults, these days they are made for
windows-like using (both Ubuntu and openSUSE).

For the cluster, we use CentOS, but this is probably just because out IT
Department insisted on that. .... SUSE has its own server OS but the
drawback is that its not free ....however, I guess one can use openSUSE
as well depending on features and complexity needed ....

Best
Vlad

Some people also use fedora. In my opinion Ubuntu and Fedora are beyond the bleeding edge, I refer to it as haemoraging edge - if you like to have the latest and greatest everything on your desktop use Ubuntu. But for a cluster it is a ridiculously bad choice - it is unbelievably fragile, especially when you start putting in things like NVIDIA drivers etc. Having designed built and shipped over 50 clusters I would never ever ever recommend Ubuntu. The only reason I ever recommend Ubuntu is for things like deep learning development boxes where the people doing the development insist on using the latest version of everything they possibly can so Ubuntu is the only place it works. It is one complete world of pain. Pretty much all the support requests for I installed XYZ and it bricked my machi

I'd also advise you not to let your students etc use it - that way at least they won't be tempted to use tons of 'k00l' new features that are utterly unbackwards compatible etc.

I'd highly recommend Bright (http://www.brightcomputing.com) although it isn't free or alternatively Rocks (http://www.rocksclusters.org/) which is free although updates can be a little sporadic and the learning curve is harder. For reference Rocks is what we use at SDSC to run our major supercomputers.
