Error with multiple threads #17

Closed GGGRY closed 6 years ago

GGGRY commented 6 years ago

Hello, When i tried to solve several eigen value problems in prallel, i met an error:

Arpack error in Aupp.
-> Maximum number of iterations taken.

Basically, i used "for" loop with openMP for parallelizing in multiple threads. I can't find any description about whether arpackpp is thread-safe or not.

All the best

Sadly it is not thread safe ( I think because arpack isn't ).

Thanks for your quick response. Well, i close this.

All the best
