vNUMA
vNUMA employs virtual-machine technology to provide a ccNUMA-like environment on a commodity cluster. This is achieved by implementing distributed shared memory in a virtual-machine monitor beneath the operating system. Thus we can achieve a true single-system-image cluster using a legacy operating system, without significant modifications to that operating system.
Current Status
Work on vNuma is currently stopped; a snapshot of the last working version is available.
vNUMA is closely related to Linux-on-Linux, a user-mode Linux running on Linux/Itanium. Both virtual machines use the same underlying technology.
