The Infiscale team is happy to make public the grand release of Perceus 1.4.0! This is the first release in the 1.4 series and undergoes a lot of changes. The primary focus of this release is scalability and ease of use. Non-specific major changes include:

• Pre-forking Perceus daemon, able to scale to thousands of nodes.
• Scalable VNFS transfer mechanism using XGET
• Rewrite of the back end database subsystem. Now it can utilize Hash, Btree, and MySQL. Other options are now possible (e.g. flat text configuration file like Warewulf used, other databases structures like the ones used in Oscar, Rocks, xCat, etc...)
• Stage one bootstrap OS has been reworked to support more types of installs, hardware, and reliability.
• Extensions to the "ipaddr" module so that it is much more capable of doing all IP addressing: static, dynamic and automatic based on probing /etc/hosts.
• New Perceus module for XCPU support right from the Perceus stage one bootstrap OS.
• Slaves (via Perceus node client daemon) now capable of load balancing and fail over between Perceus masters.
• General fixups, cleanups, code design, optimizing based on profiling, etc..

This release contains many changes so please report bugs, issues and concerns as soon as possible to help it mature quickly.

Thank you.

The Infiscale team.
