HPC systems are diverse. Programmers can’t afford to customize software from scratch for each case. We need frameworks that hide hardware behind high-level abstractions. Workflows are complex with graphs, databases, simulations, ML and more. A framework for each leads to a composability nightmare. HPC programmers need to join forces and drive a solution to this problem. In this BoF we start with graph analytics but with an eye to the wider scope of modern workflows. We bring together the GraphBLAS, SHAD, and other framework-communities to consider the frameworks we need to support the future of software in HPC.
