| Post subject: | Sparse linear constraints and parallelism |
Hi, I'm using minnlc with sparse linear constraints. Constraints are set with minnlcsetlc2. I'm experiencing that there is no performance increase with al::setglobalthreading(al::parallel) compared to al::setglobalthreading(al::serial). When I was using a dense constraint matrix, set with minnlcsetlc, the performance increase of iteration time was very noticeable. Can this be explained? |
