VRay and single 120 core pc?

[Morne]

Jip, quad socket with 4 X Intel XEON E7 4890 = 120 cores in one machine

Only $50K, I'll take 2 please

So the Dell with almost same specs (4 X Xeon 4880) came in at almost half the price of the HP

The question is: would one 12 nodes renderfarm as the fuchsundvogel one render as fast as one huge HP computer. If you count the Ghz, it's similar, but I think you have time loss with the 12nodes of the renderfarm.
can anyone confirm ?
the HP is around 50k, the 12nodes renderfarm around 6/7k

Tasks that are multi-threaded but not shared as LC will be slower.
Task single threaded will compute faster on the small desktop nodes as the clock speed is faster.
Network is one other factor.

I would rather go for a bunch 5820k with 32Gb of ram or maybe the 5960x if you need 64Gb.
You could build a node with a 5960x OC at 4.3 Ghtz with 64Gb of Ram for $1600.
You could have 30 of those for $50k.

Small nodes : 30x 12 core x 4.3Ghtz = 1032 Hgtz
Big node : 4x 15 core x 2.8 = 168 Hgtz
That's 6 times faster for the same $, sur you need to add the prince of a couple of licenses, but still...

if you go for 5820k with 32Gb of ram it's even more.

Unless you really need a huge amount of ram : 64Gb+ or do simulations like FFX, realflow, etc you don't want to go with high expensive nodes, specially for rendering.

1) What is the biggest machine we can use VRay on without having to do workarounds like this? 64 cores?

2) For the 120 core machine if we run more than one DR server on it, would each one need its own render node license?

Vlad,

I am planning to get 72 Threads for rendering (Maya vray)
If I use Linux is there still a restriction with core utilization or is this only a Windows problem at this stage?

Can Linux use beyond 64 Threads at 100% CPU utilization without some DR slave hacks??

thanks

Excerpt: Is should work.

Hey I got a 1024 core machine, is that going to be an issue?

[vlado]

hehe yeah, V-Ray currently has a hard limit of 256 cores.

Its a joke of course, but looking into the future )))
