In collaboration with the HIEPACS and TADAAM Inria teams, we are strengthening the relations between the Chameleon linear algebra library from HIEPACS, our StarPU runtime scheduler, and the NewMadeleine high-performance communication library from TADAAM. More precisely, we have improved the interoperation between StarPU and NewMadeleine, to more carefully decide when NewMadeleine should proceed with communications. We have then introduced the notion of dynamic collective operations, which opportunistically introduce communication trees to balance the communication load.
