Under CentOS the
installation is quite straightforward and simple, just be sure of activating the Perceus modules for name of hosts, group/users, ip address
and so on. I'm using NFS for provisioning rather than XGET which for some versions of Perceus is the default provisioning mechanism (XGET was much more slower and sometimes hanged, but I know that Infiniscale has been working hard on this for the latest version, so you can give a try). There is also Caos Linux distribution with the "full package" for clusters ready to go. Perceus and some other cluster-related stuff are included by default in Caos.<br><br>About the flash usb, same here, we tried it and it was quite slow.<br><br>Good luck<br><br>Sam.<br>.<br></div></div></div></div><br>
