Multithreading?

[elijah]

Is there any possibility of Gephi getting multiple processor support? I've got seven free processors and it's a real shame that I can devote 3 or 4GB to a graph but only a single processor. I know it's not easy, so I understand if the answer is no.

Also, tangentially, are there any thoughts regarding Gephi taking advantage of things like CUDA?

Hi, elijah

For now, Gephi does not improve performance with multiple processors for most of the features.
But if you need a parallel layout algorithm, you can try this http://gephi.org/2010/openord-new-layou ... hm-so-far/. To install go to tools->plugins menu and download it.

I've got OpenOrd and I'm happy with it for certain graphs but still prefer some of the other layouts for other graphs. I knew it was faster, but I didn't realize it supported multiple processors.

Gephi already takes advantage of multiple processors, but indeed could do better for layout. For instance, the visualization is in a separate thread, so it doesn't interfer with the layout. Filters, IO and other things are also executed in separated threads, as well as multiple layouts executing on diffrent workspaces.

The answer is definitely not 'no' But I see this a better fit for a Student Project than a core work.

I noticed that everything else seems to have its own thread, which is great and makes the whole package run very cleanly. I just get sad when I see my graph slowly chunk along and only 12% of my processors are being utilized. It's not a terribly big deal.
