Re: [Flightgear-devel] mpserver02 & mpserver07
An interesting stat (from the perspective of maintaining the list of mpservers) would be the last time a node was seen alive. Then if a node is down for too long we could remove it from the list and recycle the host name. And if the node does come back at some point, we can add them back in and get them a new host name.

Re: [Flightgear-devel] mpserver02 & mpserver07
Hi Curt, The email quoted below i have sent to the admins of the fgms servers that are down on 5th april 2012 and have not heard anything. I think it's best if they are recycled and if not, updated to an already existing server in the same geographical area at your earliest convenience. I have not received a single reply (nor bounces). Instead of the 14 days i initially set as a response term, its now been a period of 2 months (perhaps should have contacted you earlier), imho long enough for anybody to respond what their plan is regarding the fgms instance they have been running. And in worst case, we can always setup a new one, or restore it. Kind Regards EViL QUOTE START - Hi Admins, :) [ notification if we/i don't receive a response within the next 14 days i will request an update of the subdomain mpserver to an active server ] My name is EViL / Rob Bloemers, some might know me from the IRC network. Other perhaps have seen me crash on multiple airports around the FG world :) This email is regarding the status of the fgms instance you are running. I noticed that for a few weeks now some of the nodes are down. http://mpmap01.flightgear.org/mpstatus/ If you would no longer like to run a FGMS instance on your server, please let us know so we can have the subdomains updated to point to an active server. Also if you do want to have fgms running but there is now a long downtime scheduled for whatever reason, please let us know. We will then request the subdomain to be updated as well, until your server is back up again. We'll be glad to restore it when the machine/service is running again. But since many of the launchers and i think fgms itself, come with a fixed hardcoded list of the multiplayer servers it's not ideal to have a few outages. Many of the pilots will not really understand why multiplayer functionality is not working, others will quickly switch to another server but in my opinion it's best if we can have all the servers responding. There have also been some updates on the FGMS code, so when you have time please update the server software too. There has been a big change in the layout of the network. Previously, older versions still replicated data between all other FGMS servers. The updated software uses mpserver01 as a main hub which replicates the traffic to the other servers. Another quick notification, and perhaps unknown to some, on the irc network we have a #fgms channel, we try to keep some communication going there regarding the FGMS network. It would be great if you could join the channel when you are online. It allows quick and direct communication between and among all fgms admins. Looking very much forward to your reply, Kindest Regards Rob Bloemers aka EViLSLuT Admin of IRC / MPServer12 - QUOTE END - Original Message - From: "Curtis Olson" To: "FlightGear developers discussions" Sent: Tuesday, June 19, 2012 10:14:31 PM Subject: [Flightgear-devel] mpserver02 & mpserver07 Hi, Can anyone tell me definitively (or close to definitively, or even speculatively) what the status of mpserver02.flightgear.org and mpserver07.flightgear.org are?

Re: [Flightgear-devel] Slow frame rates
Hi Mathias, Yes, my apologies. Should have at least acknowledged your reply.. ATM all the machines with the source files and data are off line and sitting on the shelf while I work on the cockpit. Hopefully, I can bring it all on line next month and power up the sim. Then will be able to extract the relevant source and data for the warping. Also want to confirm Stuart's comments related to running multiple machines. Even if the random stuff is "deterministic" across machines if you start with the same seed, I foresee a real need, perhaps even demand, for FlightGear to live in a multi-machine federated system. Just consider what Nvidia has accomplished with GPUs running as super computers.

The nice thing is that the ipc is hidden behind something that is also able to distribute this across multiple machines. A local network connect is mostly sufficient. But doing the same by an infniband connect is possible too. Experimenting with shared memory did not bring notable improovements over a system local network connect. At least not on linux... In any case I think this could be fast enough to do this stuff. Also this stuff is based on a standard that is probably enables us to be a little more connective in the end. At least this is a slight hope from me. John, by this way, I did send you some mails regarding the unwrapping, but did never get an answer - did you recieve them?
