TBB: a solution to thread oversubscription? #656
Comments
I thought https://github.com/devinamatthews/tblis supported TBB but I can't tell anymore. You might try that. |
Yes, TBLIS has TBB support and it is almost as performant as optimized OpenMP. The idea is to port this to BLIS at some point but there is no ETA yet. |

Hello, I'm looking to use BLIS but I have a concern about thread oversubscribing due to non-composability of OpenMP. I am developing a highly parallel program using TBB flow graphs where each thread may in turn use parallel BLIS operations. I'd like to request having a configure option to support TBB to solve the oversubscription problem.
