This material relates to the use of the excellent product by VMware, Inc.. VMware enables one to run virtual machines atop a host (Linux or Windows). We use these virtual machines for testing of cluster related software as well as other random tasks.
The below links provide instruction and suggestion for use of VMware in
creating virtual machine clusters, "VMClusters", which are entirely
simulated clusters including headnodes and compute nodes. This includes
excerpts from presentations as well as notes and other semi-useful
material.
Enjoy,
