Diskless SuSE, success at last

SuSE has been resisting me running it diskless. Actively resisting. The end result was that I had to build a custom kernel (we are using/supporting 2.6.22.6 right now), making sure to build nfs, and networking in, and not as modules.

And yet another learning moment

DragonFly milestone

A long time ago, on a computer not so far away, we built a program called “SICE”. Yeah, I am not known for naming things well. SICE’s entire purpose in life was to be a user centric interface to HPC systems. When users wanted to run jobs, they filled out a web form that described […]
