=== INtroduction ===<br />
<br />
The following milestone completion document applies to Subproject 1.1 – SMP Node Affinity subproject of the Single Metadata Server Performance Improvements within the OpenSFS Lustre Development contract SFS-DEV-001 signed 7/30/2011.<br />
<br />
Per the contract, Implementation milestone is described as follows: “This subproject splits the computing cores available on the Metadata Server (MDS) into a configurable number of compute partitions, and binds the Lustre RPC service threads to run within a specified compute partition. This allows the RPC threads to run more efficiently by keeping data structures in cache memory close to the CPU cores on which they are running, and avoids needles contention on the inter-CPU memory subsystem. SMP Node Affinity also allows individual RPC requests to stay local to a specific compute partition, improving overall efficiency throughout the protocol stack as the number of cores increases.”<br />
<br />
Per the contract, Implementation milestone is described as follows: “Contractor shall complete implementation and unit testing for the approved solution. Contractor shall regularly report feature development progress including progress metrics at project meetings and engineers shall share interim unit testing results as they are available. OpenSFS at its discretion may request a code review. Completion of the implementation phase shall occur when the agreed to solution has been completed up to and including unit testing and this functionality can be demonstrated on a test cluster. Code Reviews shall include:<br />
<br />
# Discussion led by Contractor engineer providing an overview of Lustre source code changes.<br />
# Review of any new unit test cases that were developed to test changes.<br />
<br />
== Location of Completed Solution ==<br />
<br />
The agreed solution has been completed and is recorded in the following patches:<br />

<br />
==== SMP Node Affinity does not require new functional tests as this project is a performance enhancement. ====<br />
<br />
During the course of development, two small changes were made to the existing tests.<br />
<br />
# Force enable multiple CPU partitions for autotest. By default, libcfs will create multiple CPU partition only for system with > 4 CPU cores. It is preferential to run test with multiple CPU partitions for all SMP machines. A patch was developed to always enable multiple CPU partitions on systems with multiple cores<br />
# Minor issue fixes. Now multiple CPU partitions are provided modifications to the tests were required to work around brittle interractions between autotest and the procfs subsystem.<br />
<br />
These changes are recorded as[[#change,3288|]]http://review.whamcloud.com/#change,3288<br />

A subsequent test on IB is included in Appendix 2 recorded at [https://maloo.whamcloud.com/test_sessions/2912130e-fd4f-11e1-b09c-52540035b04c https://maloo.whamcloud.com/test_sessions/2912130e-fd4f-11e1-b09c-52540035b04c]<br />
