I'm in the process of setting up a compute cluster with the intent of using it for some parallel computing experiments. I have a single executable which I'd like to run on this cluster.
Due to operational constraints on said cluster I can only deploy this executable as a PXE boot image. Unfortunately, the only "ready-made" images I've been able to find are installation ones intended to install a particular distro. They don't particularly appear easy to modify.
Can someone perhaps provide some pointers as to how I could go about creating a pxelinux image that loads the linux kernel and subsequently run an executable?
