14:11:07 <mackonstan> #info Maciek - summary of where we are with CSIT-2005 benchmarks:
14:14:16 <mackonstan> #info Summary:
14:14:17 <mackonstan> 1. Moving from 2005.0-3 to 2005.0-4 made the comparison clearer but further work is required  (-3 and -4 are CSIT environment versions).
14:14:17 <mackonstan> a. -3 to -4 change is reverted TRex 7to15-workers change, that has introduced different packet burst profile, and potentially also different packet flow sequencing on the wire.
14:14:17 <mackonstan> b. -3 was responsible for a large number of regressions with vhost and memif packet paths.
14:14:17 <mackonstan> 2. Inconclusive bisecting of identified 2005.0-4 vs 2001.0-2 progressions.
14:14:17 <mackonstan> a. Findings to-date are inconclusive from the VPP code point of view, indicating impact of further CSIT changes, in addition to TRex 7to15-workers change that has been already reverted.
14:14:18 <mackonstan> 3. In order to address point 2., we agreed to do following
14:14:18 <mackonstan> a. Separate out any CSIT changes by re-applying comparison methodology developed in CSIT-2001 cycle, and test vpp v20.01.0 in CSIT-2005-4 environment.
14:14:18 <mackonstan> b. Focus on bisecting identified 2005.0-4 vs 2001.0-2 regressions only.
14:14:19 <mackonstan> c. This approach is consistent with what has been done in CSIT-2001 to address skx and clx ucode induced CSIT environment change.
14:16:08 <mackonstan> #info Tibor to run 2001.0-4 set of tests (vpp v20.01.0 tested in CSIT-2005-4):
14:16:08 <mackonstan> ◦	4 runs on 2n-clx.
14:16:08 <mackonstan> ◦	1 run on 2n-skx, 3n-skx, 3n-hsw, 3n-tsh.

14:23:54 <mackonstan> #topic Releases CSIT-2001, CSIT-1908.2
14:23:58 <dwallacelf> #info Once the definition of "CSIT environment" is complete, the release schedule should include appropriate freeze dates on env changes so previous release testing can begin early in the release cycle.
14:24:04 <mackonstan> #info no updates
14:24:39 <mackonstan> #topic Physical Infrastructure
14:29:02 <mackonstan> #info Arm build servers - Juraj, Peter working directly with Vexxhost - latest status in Vexxhost ticket (2 servers still dead). Separate tickets for each. Need to coordinate with on-site presence in DC.
14:30:42 <mackonstan> #action Juraj, Peter, Maciek - propose a consolidated way-forward proposal to address all Arm servers down tickets (3 servers in total, 2 build, 1 thunderX).
14:31:25 <mackonstan> #topic Virtual Infrastructure, CI/CD
14:32:42 <dwallacelf> #info Dave running ping monitor scripts and updating Vexxhost ticket daily.  Will send out instructions for running scripts while I'm on PTO.
14:33:39 <mackonstan> #info Juraj - question of about adding new jobs, want to add Centos job, question to DaveW
14:34:57 <mackonstan> #info Juraj - all details in email from xxx, Juraj to confirm
14:35:17 <mackonstan> #topic Environment, Framework
14:35:27 <mackonstan> #topic Performance Tests
14:37:37 <mackonstan> #info Vratko - tests using DPDK plugin are failing, per VPP build all tests using DPDK plugin are either failing or passing
14:38:05 <mackonstan> #info Peter - saw some discussion on this topic, will investigate it
14:38:23 <jlinkes> Jieqiang wang
14:38:51 <mackonstan> #info re above `xxx` note, it is `Jieqiang wang`
14:40:07 <mackonstan> #info Maciek, Jan, Maros - work continues with NAT44-EI and -ED, using TRex ASTF and TRex STL with symmetric burst profiles
