Re: Project data locality performance penalty

Hey everyone,

Just wanted to follow up on this. I'm going back on-site to the ofice on Thursday and I'd love to be able to implement some change(s) that may make this faster.

I'm keen to get any suggestions from the community around keeping projects on central storage without sacrificing 80% of ...

Re: Project data locality performance penalty

Hi aoktar, thanks for your reply, and I'm sorry about the delay in mine.

The difference is about 5x between rendering with the project files on the NAS vs on the render master's local drive.

I have some excel files with the results of various tests, but basically when the data isn't local it's ...

Project data locality performance penalty

Hey aoktar and everyone,

We've been unsuccessfully trying to figure out how to eliminate a major performance penalty we're seeing with using Octane when storing/opening C4D projects from a NAS. Even with 10G networking to the workstations and flash-based storage in the NAS, we're seeing massive ...

Re: Network storage suggestions

Just a quick addition - I'm trying to work out how to use a standardized measurement to evaluate changes I make to the configuration. As As mentioned, I've isolated the performance to data locality (as opposed to render locality) - if a project lives on the NAS it takes much longer to transfer and ...

Network storage suggestions

Sorry, had posted this incorrectly in the wrong area of the forum :?

Hey all, need some help working through a significant bottleneck we've run into doing Octane renders with Cinema4d.

We have a 10gbe network - 10gbe to NAS, render masters, and render slave. NAS can push and pull at 300-400 mbps ...

Re: Network renders remarkably slow

We have 10GB networking to everything: workstation, NAS and slave. Obviously something is getting in the way, maybe my NAS read speed, because when copying the work files to a workstation, it's a little bit faster. Who has a lot of expereince making network rendering super fast? Assuming that ...

Re: 10-GPU SuperServer by SuperMicro

@glimpse I don't believe octanebench works with pascal cards. Recommendations?

Someone also said something about using TCC drivers to get around the windows limitations. Anyone have experience with those drivers and would they work in this scenario to help get all 10 cards running under Windows?

Network renders remarkably slow

Hey all,

We run a new powerful gpu server that basically only does Octane. It has 6x 980ti and 4x 1080s in it.

When we're doing our quarter res work, we do a lot of renders in succession quickly. We have discovered through trial and error that since v3, network rendering has become much slower for ...

Re: 10-GPU SuperServer by SuperMicro

No, there is no error message on launching the daemon run script, it just asks for login credentials every time. I can do some permissions checking. Thanks.

Re: 10-GPU SuperServer by SuperMicro

Hey all,

I thought Octane scales linearly with the number of GPUs? Why not build a couple of 4x systems and just use as slaves? I haven't tried it yet so anyone who has experiences should chime in.

I'm not the Octane user but I believe this has to do with rendering large jobs quickly; perhaps ...
