Boost graph : Are add_edge and remove_edge thread safe?

Question

Are add_edge(src, dst, g) and remove_edge thread safe ? Can these operations be done concurrently with multi-threading parallelism ?

Thanks.

Answer 1

No.

Unless stated otherwise, no data structures/algorithms in the boost library are thread aware.

Also, these are generic free functions operating on the underlying graph type. So the thread-safety would depend on the underlying type.

In general, this makes add_edge and remove_edge thread neutral at best
