Still a newbie in HPC, in the first stages of building a Beowulf
cluster (8 nodes).
I wonder if anybody out there has used Linux virtual machines in
the head node, just to be able to experiment with different
configurations & deployments and jump back without much effort if
things go bad. Considering (out of experience in desktop) VMWare or
Sun Virtualbox. Any hints, comments ?
I was also just thinking of it in the last couple of days. In the
past often a dedicated login- and dedicated file-server was used to
split the load. Putting the login-node in a virtual machine will
still keep the users away from the file-server, but allows you to
combine them in one piece of metal when it's powerful enough. Or
maybe even one virtual login node per user, when you don't allow
anyone seeing the actions of others.
To operate Sun VirtualBox w/o the graphical interface is possible,
and you can also direct the virtual console to any remote machine
using "rdesktop" as client on any platform you like.
