Re: [igraph] c stack problem

[Gary Weissman]

I am not an expert on threading, but was planning to use R-igraph in a parallel environment using Rmpi under OpenMPI.  Are there restrictions on this approach with igraph not being thread-safe?

Thank you for your work on igraph!

Best,

Gary

Hi Roberto,

The short answer is that igraph is not thread-safe, so you can only use
igraph from one thread at the same time.

The long answer was discussed last year in a discussion thread that starts
here (follow the thread for the answers):

However, you could probably speed up your code a bit by constructing the
edge list first and then adding the edges in one batch using igraph_add_edges.
