Hi,

Thanks for your great work!

I'm not sure about one thing: Is Eigen thread-safe? I mean if I take care myself not to read and write on the same elements.

Can I use multiple threads to read elements in parallel in the same matrix ? And can I write elements in the same matrix if I take care to never edit the same element at the same time ?

I ask this as my code, that was stable, now crashes randomly after I introduced multi-threading, and I cannot find the reason for it now.

Thanks

Yes it is, in that sense.

Yes, just like reading from any plain buffer.

And can I write elements in the same matrix if I take care to never edit the same element at the same time ?

Yes, assuming you're not at the same time reading from a part you're overwriting in another thread, for the same reason, plain buffer.

I can't either

Thanks for this quick answer !
