Hey people! I am interested in building a small cluster. At this lab I work for, we have a bunch of Pentium IV 1GB RAM computers we no longer use. To retain them from uselessness, we are thinking of the possibility of building a small cluster. I have read a few guides, but most are over 10 years old. My question is: is there any up to date guide that is not completely technical? I have read about master and slave nodes. Is there any way to connect a few (four or five) of our computers to this cluster? Thanks in advance.
