Crash when running multiple instances of BFF on a multi-threaded environment about boundary-first-flattening HOT 4 OPEN

Thanks @calvariomind! Unfortunately, the current version is not thread safe because of how it is linked with Cholmod. However, it is possible to make the Cholmod dependency thread safe. I've listed this issue as an enhancement :)

Thanks for the quick reply rohan :)
If I understand correctly, the limitation is on cholmod library, not on BFF. Can I do something on my side to resolve the problem without changing BFF code? Maybe linking with a different version of cholmod?
Thanks

I should correct myself - some of the BFF linear algebra code will have to be modified, starting with not declaring a global cholmod Common object but rather cholmod Common objects local to each thread. I'll have to put some more thought on how exactly to architect this within the BFF codebase. If you don't want to dig into cholmod, another option might be to replace the implementation of the BFF linear algebra wrappers (such as DenseMatrix, SparseMatrix, Cholesky) with another library such as Eigen.

Thanks again for your answers. I will continue using BFF as is, without multi-threading. It is fast enough for my current purposes. I will be watching for new versions, and reactivate the multi-threading in case you decide to make those changes.
Congratulations for a great library :)
