2020 SUG meeting week #49

Walsh County, October 2020 – blog post

The following notes were taken from the Tuesday, December 1st Simulator User Group (SUG) meeting.

Server Updates

  • On Monday, November 30th, the simulators on the SLS Main channel were all updated to version 552571, matching the RC channels.
  • Originally, it had been planned to follow this with a tight series of rolls over the next few days, with simulators updated in batches at roughly 16-hour intervals. However, at the time of writing this is on hold, as Rider Linden explained:
That plan, like so many others, is now up in the air. There are a couple of last minute snags that we ran into and so we’re evaluating what the best way to do these deploys is going to be and we do not yet have an answer. We will keep you all informed on the blog where things settle out.

This means that – again at the time of writing – the rolls listed on the grid status pages are TBD, and subject to update from LL.

No Change Window

Normally, December sees a limited number of deployments for the simulators, with a “no change” window coming into effect over the holiday period  (usually from just before the Christmas break to just after New Year’s day).

However this year, thanks to the migration work, this are apparently more fluid, and dates – if any – have yet to be announced.

SL Viewer

The Start of the week has seen no change to the current crop of official viewers, leaving them as follows:

  • Current release viewer version 6.4.11.551711, formerly Cachaça Maintenance RC viewer promoted on November 12 – No Change.
  • Release channel cohorts:
    • Custom Key Mappings project viewer, version 6.4.12.552100, November 12.
  • Project viewers:
    • Simple Cache project viewer, version 6.4.11.551403, issued on November 12.
    • Project Jelly project viewer (Jellydoll updates), version 6.4.11.551213, November 2.
    • Legacy Profiles viewer, version 6.4.11.550519, October 26.
    • Copy / Paste viewer, version 6.3.5.533365, December 9, 2019.
    • Project Muscadine (Animesh follow-on) project viewer, version 6.4.0.532999, November 22, 2019.
    • 360 Snapshot project viewer, version 6.2.4.529111, July 16, 2019.

In Brief

We know what’s going on but unfortunately it’s going to take a bit of time before we can have a fix. Some of the other work on getting to the cloud needs to get done first. It’s complicated by how inter-dependent our systems are.

2020 SUG meeting week #48: Uplift update

Time Remains, October 2020 – blog post

The following notes were taken from the Tuesday, November 24th Simulator User Group meeting.

Server Updates

Please also refer to the week’s server deployment thread.

  • On Tuesday November 24th,  RC channels were updated to simulator version 552571, comprising “some bug fixes and internal tweaks”. However, one fix should correct the inability to correctly set permissions (e.g. edit rights) for friends.
  • There is no planned SLS Main channel deployment for week #48.

Week #49

If all goes to plan at the Lab, week #49 (commencing Monday, November 30th) will see a daily series of rolling restarts across the grid. Due to start on Monday, this will be batches of regions being restarted, with the plan that restarts are staggered to avoid too much disruption, and if everything proceeds smoothly, each region should only be restarted once at some point in the week.

Commenting on the restarts, Maxidox Linden stated:

I think it will be something like at most 14-16 hours between rolls. Though as Rider says unless something changes we don’t plan to roll the same region in two successive rolls. And we’re going to do our best to avoid times with tons of people on-line if we can.

These deployments are liable to occur at 16-hour intervals.

Uplift Status

As per my blog post from week #48 (see: LL confirms Second Life regions now all on AWS), whilst all regions are now running on AWS services, the work in transitioning all of the Second Life back-end services is not complete, and LL are still “operating with one foot in either camp” – and this may be exacerbating the problems currently being experienced by some.

Another factor could be the different communications routes between viewers and servers following the move from operating out of the Lab’s co-lo facility in Arizona to the Amazon centre in Oregon. For some, this has definitely resulted in a noticeable increase in basic ping times to / from the servers, although for others, this has barely changed.

Commenting on the general state of play, Mazidox Linden observed:

We are not yet at what I would call “Final uplift performance” (that is to say, without any explicit attempts at tuning performance and behaviour of system communication). There is still plenty of stuff making that round trip over hundreds of miles to the data centre, slowing things down.

In this respect, some of the issues people are noticing at the moment may be down to the fact that LL haven’t as yet started fine tuning things, and are unlikely to do so until all services are running via AWS. As such, some of the problems people are noting might be down to this. In this respect, Oz Linden noted:

We’re much more focused right now on getting things other than the simulators uplifted and fixing anything that really breaks. Performance problems are a step down in priority until that’s done, but we won’t forget about them.

SL Viewer

The Start of the week has seen no change to the current crop of official viewers, leaving the as follows:

  • Current release viewer version 6.4.11.551711, formerly Cachaça Maintenance RC viewer promoted on November 12 – No change
  • Release channel cohorts:
    •  Custom Key Mappings project viewer, version 6.4.12.552100, November 12.
  • Project viewers:
    • Simple Cache project viewer, version 6.4.11.551403, issued on November 12.
    • Project Jelly project viewer (Jellydoll updates), version 6.4.11.551213, November 2.
    • Legacy Profiles viewer, version 6.4.11.550519, October 26.
    • Copy / Paste viewer, version 6.3.5.533365, December 9, 2019.
    • Project Muscadine (Animesh follow-on) project viewer, version 6.4.0.532999, November 22, 2019.
    • 360 Snapshot project viewer, version 6.2.4.529111, July 16, 2019.

In Brief

  • Group Chat: There has been an update to the Group chat servers which the Lab hopes will help alleviate the issues of the last couple of months. The hope is that as a result of this, things should be somewhat better, although it is acknowledged things are “not perfectly solid” as yet.
  • Map Tiles: there is a known issue with in-world Map tiles failing to update. At the time of writing, there was no ETA on when a fix will be implemented.
  • Teleports: people are still reporting teleport failures, although data collected by the Lab using additional logging apparently shows the overall level of teleport failures as being back to “normal” after the recent spike.
  • Textures: Slow texture loads: people are reporting slower than usual texture loading. When isn’t currently understood (given textures are among the data coming to users via the CDN, so not directly a part of the AWS transition). The speculation offered by Oz Linden is that where texture messaging is concerned, it may not be going as fast as LL like.
  • Scripts: there have also bee reports of some regions initially showing improved script performance, only to apparently drop back to “pre-uplift” levels of processing. Commenting on this, Maxidox Linden stated:
 If you’re seeing changes to scripts run the likely explanation is that there is contention for shared system resources beneath the simulator layer. That is something we had only mild control over before and have even less control over now..  That said, it’s on our radar. I can’t promise that even when someone gets time to look at it there will be anything we can *do*, but we are aware, and we’re not ignoring it. …
I mean, it is almost possible that we’re calculating that number wrong Lucia, because we have certainly changed the hardware the simulators are running on in ways that the people who made that statistic probably never imagined. I’m not going to swear that is or isn’t happening, but it will certainly be one of the many things we look at.

2020 CCUG meeting week #47 summary

Ruegen, October 2020 – blog post

The following notes were taken from my audio recording and chat log of the Content Creation User Group (CCUG) meeting held on Thursday, November 19th 2020 at 13:00 SLT. These meetings are chaired by Vir Linden, with dates available via the SL Public Calendar.

The venue for meetings is the Hippotropolis camp fire.

SL Viewer

At the time of writing, the current selection of official viewers (release, RC and projects) was as follows:

  • Current release viewer version 6.4.11.551711, formerly Cachaça Maintenance RC viewer promoted on November 12 – NEW.
  • Release channel cohorts:
    •  Custom Key Mappings project viewer, version 6.4.12.552100, November 12.
  • Project viewers:
    • Simple Cache project viewer, version 6.4.11.551403, issued on November 12.
    • Project Jelly project viewer (Jellydoll updates), version 6.4.11.551213, November 2.
    • Legacy Profiles viewer, version 6.4.11.550519, October 26.
    • Copy / Paste viewer, version 6.3.5.533365, December 9, 2019.
    • Project Muscadine (Animesh follow-on) project viewer, version 6.4.0.532999, November 22, 2019.
    • 360 Snapshot project viewer, version 6.2.4.529111, July 16, 2019.

General Viewer Notes

  • The Custom Key Mapping viewer is thought to be reaching a point where it can be promoted as the de facto release viewer.
  • A new Love Me Render (LMR) RC / project viewer is due to be issued. LMR-5 will include non-EEP bug fixes.
  • The Copy / Paste project viewer is on hold as a result of running into UI complications, and is currently awaiting further work by the viewer UI team, or possibly a decision to scrap the viewer entirely.

ARCTan / Jellydoll / Imposter Avatars

  • Vir has most recently looking at timers / frame rate variability.
  • As a reminder:
    • The current ARCTan work is focused on the viewer-side updates to avatar complexity calculations.
    • Work on providing in-world object rendering costs (LOD models, etc.) which might affect Land Impact will be handled as a later tranche of project work, after the avatar work.

Graphics

  • Work has commenced on separating out the rendering of viewer UI elements from scene rendering.
    • The reason for this is that the UI currently gets rendered on per frame basis, which is performance expensive on what is essentially a relatively static element of the viewer.
    • The aim is to revise the UI such that it is only re-drawn was needed, and it is hoped this will result in a performance gain in terms of viewer frame rates.
    • When this work is in a condition where it can be released, it will appear in its own project / RC viewer, and not as a part of the Love Me Render graphics-specific viewer pipeline.
  • No news on work for replacing OpenGL.

In Brief

  • There may be an issue with the viewer ignoring avatar custom joint positions if they do not have a weight associated with them. This appears true for .DAE files exports from Maya, and possibly with exports from Blender 1.7.9.a / 1.7.9.b (although Avastar may automatically compensate for unweighted custom joints by given them a default weighting). However, it is not clear if the issue lies with the modelling software or the mesh uploader, and its been requested that those experiencing these issues check the mesh upload data to see if anything is being pruned.

Date of Next Meeting

  • Thursday, December 3rd.

2020 SUG meeting week #47: uplift

Paradise on Sea, October 2020 – blog post

The following notes were taken from the Tuesday, November 17th Simulator User Group meeting.

Server Updates and Cloud Uplift

Please also refer to the week’s server deployment thread.

  • On Tuesday November 17th, the AWS RC channels were updated to simulator version 552183, which includes internal configuration changes, and the outcome of this deployment is being monitored.
  • On Wednesday, November 18th, the rest of the SLS Main channel may be migrated to running on AWS, with simulators on that channel also running sever update package 551942, which will mean all main grid (Agni) regions will be running via AWS. However, this is currently fluid – check the deployment thread for updates.
  • There may be a further deployment on Thursday, November 18th. Again, check the server deployment thread for updates.

Additional Notes

  • Due to  known issues with regions running on AWS, the Lab will continue to run Debug1 and Debug2 from their co-location facility,  for residents who need to to use for workarounds to these issues.
  • It is hoped that the configuration changes will help improve the recent TP failure and group chat  issues many have been experiencing – however, this is dependent on the above-noted monitoring of the simulator update.
