Re: [hugin-ptx] Re: Hardware: Cost efficient cluster for stitching?

have you seen this?
http://helmer.sfe.se/

its a couple of years old now, and I'd prob do it now something like the
2600. or i guess more of them with a cheaper chip. but that it a good cpu
for the price

the other option you can go is something like a 4p opteron system with
either 32 or 48 cores. if you get the base cpu they work out quite well
price/performance. though you would need a fast storage to feed it. and you
probably would want to make a bunch of virtual machines out of it.

I'm not sure which hugin would prefer but your work load is probably more
suited to more low end nodes.

here's a list cpu's value/performance

 and have you tried running muiltiple renders on your 6 core amd?

 my first thought is your transfer speed may become a bottleneck.

 my thought would be to get an intel 2600 enough ram to cover 8 jobs at
 once and an ssd that good at multitreaded read.

 though it may run faster to disable hyperthreading and just run 4 jobs at
 once.

 quite a lot of experience with Sun Grid Engine on very large/expensive

 What I am looking for is to build a cluster from many cheap boards and
 CPUs, that provides a better performance per Dollar.
 Not a fast PC on a budget.

 Something like 10 boards of 150 USD each that provide 6 times the
 performance, bust just cost twice.

 Is there really nobody whom runs a rendering farm?

that insight3d looks amazing.

I'm going to have a look at this.

  I would invite this guy to join us!!!
 

 Where can one join? The website only gived the mail address of the
 author.

 Also, did anybody get this to run? I managed to compile it on Linux
 after some tinkering, but only got a segfault after trying to match
 images.

 Cheers,
