Some disclosed embodiments are directed to computing systems having different accelerators such that a first set of accelerators has a greater memory capability than a second set accelerators, while the second set of accelerators has a greater processing capability than the first set of accelerators. A machine learning model having different dense layers and sparse layers is distributed on the different accelerators such that the dense layers are distributed on one or more accelerators selected from the first set of accelerators and the sparse layers are distributed on one or more accelerators in the second set of accelerators.
