The star browser doesn't seem capable of much, with a search for all stars within a mere 100 light-years taking twenty seconds on my excellent laptop. But would it be possible for a supercomputer to scan every single celestial body in Space Engine within a reasonable time frame? It would be great fun, perhaps useful for finding bugs, and most importantly would let us find the One True Largest Star (before size was capped).

This can be easily calculated. Take your scan time, divide on number of cores and Ghz, and you'll see the scanning performance. Then multiply on supercomputer specs... I had answered this several times on this forum and on the old one. Scanning the single galaxy would take millions of years even for supercomputer.

That's ridiculous... the Milky Way is only about thirty million times the scale of the star browser search, so it would take my laptop fifteen years. Against a supercomputer with millions of cores?

Keep in mind that whatever size you specify, SE currently won't scan more than 10.000 stars in one go, as you can note by keeping an eye on the counter. Milky Way is listed as having 270 billion ones as of the last version given to us beta testers.

That's just an ingame limitation. I imagine a serious attempt at scanning everything would proceed differently.

That's right. Your PC would overload and crash, if not outright melt
Come on dude, stop complaining about everything. If there is a mistake or limitation, it has a reason to be there.

Who's complaining? Going over 10k wouldn't be much use for most people.

For most people no but I'd love to have the option to go over that amount. It doesn't even have to be something in the GUI but perhaps something we could specify in a .cfg? I wonder if Space Engineer would consider this at some point? Computers are always getting more powerful so it would be a "nice to have" option for some of us who have Space Engine running on large multicore servers.

Actually it is a GUI limitation. SE generates a huge table, 10k lines is too large already.

Another limitation is how stars are get "scanned". Engine have to generate ALL stars within a specified radius. It is not a problem is radius is <50 ly, there are ~10k stars out there. But if you increase it twice, there will be 8x more stars. Increase it 4 times, and you will have 64 more stars (6.4 million). And so on. Star generator is not multi-threaded (unlike plantary system generation), generating all octree blocks containing those 6.4 million stars would take several minutes, during which SE will not respond. Users will complain that SE is hunging during star search. This is the main reason why I introduced the 10k stars limit. After star list is filled, SE starts to generate the planetary system for each one, and compare it with the planet/moon filter. This stage is multi-threaded, so engine is not hungs you can see a gradual update of the table (untick the "Filter" box in the lower left corner).

Other way to limit could be a search radius, but it may be different in different parts of the galaxy, depending on a local star density. And there is a filter by main system's star class, SE can filter out systems by this parameter prior to generation of planets. Use this if you want to search the Earth twins near G stars (I suppose in 90% cases users doing this in the star browser). This way you may increase the search radius and still be within 10k limit. But be patient, you computer may hung during generation of stars for several minutes.

That boggles the mind wow.

I just wanted to thank you SO much for this highly detailed explanation and possible workarounds. It means a lot that you took the time to post this. Onward and upward!

You own a server- wow.  I just did a new build with new components (the reason I was absent for so long), but I thought shelling out 2K for all the components was a splurge on my part, but didn't even dream of buying one of those servers.
