psutil, python, and icc

I used to dislike dependency management because there are so many things that require root or are mysteriously incompatible with each other. However, I recently came to realize that the existence of dependency itself is a delicate and elegant system despite being messy at times. The recent occasion that reminded me the beauty of dependency was to install psutil on an HPC. It ran CentOS 7, and I had Python 3.

Dealing with dependency without sudo like a dummy (again)

The more I work with Linux, the more I encounter dependency issues. This is of course not too big a surprise, but it can be painful especially when you aren’t sudo, so the most obvious solution does not work for you. Don’t misunderstand me. sudo is definitely not something to play with when we don’t know what we are doing, and access control does a terrific job preventing me from shooting my own foot (or worse, other’s foot) from time to time.
