Small shell script that returns the details in /proc/cpuinfo in a more human readable and relevant way.

Sample output

Processor seems to be quite old guessing number.

Useful Scripts

Intro:

This section contains the scripts I use to quickly redeploy the nodes. The “Post Script” could be improved a lot and also made more generic, however I’ll leave that as a task to the user, I may update it at some point if I have a need.

Overview and installing the operating system

Intro:

To facilitate testing of our software and so that support can model possible customer environments I was tasked with setting up a cluster with infiniband. I was excited as the system was a Dell PowerEdge blade cluster (our 1st blade system) and we have never used or deployed infiniband (this would be our 1st infiniband system), in fact other than a basic “we have heard of this and know (very) roughly what it is” no-one in the group had any real knowledge of it. After a few hours of searching the deepest recesses of the Internet I had a limited understanding of how to setup the system. I know how irritating it is to have to read the crud in order to find that wee gem of info so from here on I’ll mark the paragraphs of the article so those of you wanting to “just get it done” can skip them.
