the designs reflect a certain point in time to the extent that a design finds itself in a feature in a release there will be other pages and assets on the wiki. Some of the information may not be current ... more historical. Latest presentations are current. The rest needs to be in an archive place. Some content may be out of date.

About once a year, the Lustre Engineering team gathers to discuss new features under development and testing efforts.

The Lustre team has prepared several design documents as part of the HPCS program. The DARPA High Productivity Computing Systems (HPCS) project is a program created to ensure that US Government agencies continue to have access to the advanced high-performance computing technologies needed to fulfill their missions. The program objectives include achieving extremely high IO performance and file system scale and reliability. Cray Inc. has partnered with Sun to use Lustre to achieve these goals.

In November 2009, the senior Lustre engineers met in conjunction with the SC'09 event in Portland, Oregon, to discuss designs for upcoming features and implementation status of current development projects.

The following presentations and design documents describe new Lustre features currently under development. They were made available as part of the the DARPA High Productivity Computing Systems (HPCS)project or presented at Supercomputing 2009 (SC'09).
