Pointer to a thread over at hpccommunity.org announcing the first release of SnowFlock
we’re releasing Snowflock to the general public. We’re making a binary and source relase, under the GNU General Public License (GPL). The release is available at Snowflock – Impromptu Virtual Clusters.
Briefly, Snowflock lets you clone Xen VMs into dozens of identical replicas running in different hosts. Snowflock can do this in less than a second and with very low runtime overhead. With Snowflock you can, for example, perform parallel computations on the fly by scaling “instantaneously” your computing footprint in a shared cluster. Snowflock is a research prototype, hence the 0.1 major-minor. A minimum degree of experience with Xen and Linux is necessary to use the system. The contact address for snowflock is firstname.lastname@example.org.
Great name, by the way. Creative, evocative, but still easy to spell. More in the thread.
