[INFO] Successfully tested varregions
The new, larger regions enabled by varregions have been tested successfully on the grid overnight. These are possible following the upgrade to OpenSim 0.8 (release).
There is currently a 1024x1024 1280x1280 test region called Rheged at 2000, 2000, i.e. four five times bigger in x,y coordinates and thus a square area 16 25 times bigger than the default 256x256 regions inherited from Second Life™.
Larger regions take longer to load in the viewer. We tested a region at the maximum size of 8192x8192 (32*32=1024) but it crashed the simulator both times we tried it, perhaps because it consumed too much memory in start-up; however, 4096x4096 (16*16=256) worked successfully before we downsized it back to 1024x1024 (4*4=16), later increased to 1280x1280 (5*5=25) in order to be able to upload the Mars Var25 1280x1280 terrain.
Currently, such regions must be square and require the BulletSim physics engine, not the older Open Dynamics Engine (ODE). It is possible to load OAR archives from normal-sized regions by offsetting them to the correct location but it is not currently possible to do the same with terrain files.
Varregions were ported from code originally developed for the moribund or possibly defunct Aurora-Sim project, a fork of OpenSim whose web site has recently become unavailable at the time of writing: the code is still available on GitHub. Aurora-Sim has now been replaced by its own, more recent fork WhiteCore. A wide range of other features including underwater and centred gravity physics, safe scripting of C# and VB script, "Display Names" etc have not been ported to OpenSim.
[COMPLETE] Upgrade to OpenSim 0.8 (release)
The upgrade was performed successfully. All systems are working as normal, including groups, profiles and offline IMs (which used to be frequent casualties of upgrades in the past). BulletSim is now the default physics engine, replacing the Open Dynamics Engine used until OpenSim 0.7.x versions.
[COMPLETE] New web site
The web site has been migrated to the Joomla! content management system, which is more flexible and easier to manage.
Some small sections of PHP code have been migrated from the Wiredux platform, which appears to be essentially unmaintained, and are therefore available under the same licence as listed on their GForge site. All other content is unaffected.
[INFO] Ocean Grid is four years old
Ocean Grid is now four years old! Hooray! :-D
The grid was created on 16 March 2010.
However, the grid's home region, Annwfn, is the oldest region now on the grid, created on 21 October 2010 at 11:26:24 am. Of the others in the group of four home regions, Gododdin was created just under half a minute later at 11:26:53 am, Celyddon was created under four minutes later at 11:30:08 am, and Aeron was probably originally created at almost the same time, though the present region was re-created over 77 days later on 6 January 2011 at 11:50:07 am.
[IMPORTANT NOTICE TO ALL USERS] Domain name change
will shortly be changing have changed over to the new domain name oceangrid.net so the preferred URL will be is now http://oceangrid.net when this is completed with immediate effect. The old URL http://oceangrid.servehttp.com will work for a time no longer works. You will need to update the details in the grid list of your viewer in order to continue to connect to the grid after this time.
In addition, the IRC/XMPP server
will also be has been moved to http://eigion.net and the old URL http://eigion.servehttp.com will work for a time no longer works. You will need to update the details that you use to connect to the server in your IRC or XMPP client programme in order to continue to use it after this time.
