	Variability should be communicated from the raw results through to the validation metrics.		Attendees: James, Jinshan, Doug, Richard, John.

			"Variability should be communicated from the raw results through to the validation metrics."

			"Schedule wasn't too bad: six weeks behind on demo, four weeks behind on Landing."

			"Good headlines for the project: 89KLOC removed."

			"Clean-up project was not overwhelming. One-or two regressions. Exposed problems in the test suite. Really need to figure out why they only become visible after time. go back and analyze why this issues aren't immediately."

			"Thought it went pretty well."

			"Spent time re-basing and avoiding collisions. Topic branches would be useful for something like this in the future."

			"CLIO work was separated well from the DNE2 and LFSCK3/4 work areas. This avoided costly collisions during landing"

			"Test matrix needed to be made available to assist communication, record configuration, and communicate data."

			"Using the OpenSFS wiki as the canonical project tool worked well. It allowed our work to be visible and avoided copying work between wikis."

-The goal of the CLIO Simplification Implementation contract is the implementation in the Lustre source code of the CLIO Simplification Design that resulted from [[Media:CLIOSimplificationDesign_HighLevelDesign.pdf|Project 2]] of [[Contract SFS-DEV-003]].
+The Lustre client implementation for the IO path (called CLIO) is responsible for issuing RPC commands for reading and writing data to the OSTs. CLIO was reconstructed in Lustre 2.0 for cross-platform portability. The CLIO implementation is too complex for the current usage, thus making the code hard to understand and maintain. This project implements the tasks described during work for OpenSFS contract 003 (see below). This work includes:
